- Line 62: Extend the test named “API Route dedicated credentials require the
canonical inference URL” to assert that resolveRouteCredentialValue returns
undefined for the plaintext URL http://global.api-route.com/v1, preserving the
HTTPS-only credential boundary.
- Around line 50-52: Add model precedence assertions around
getProviderPresetUiMetadata for api-route: verify API_ROUTE_MODEL takes
precedence over OPENAI_MODEL, and verify OPENAI_MODEL is selected when
API_ROUTE_MODEL is absent. Keep the existing default-metadata coverage
unchanged.

In `@src/integrations/gateways/api-route.ts`:
- Around line 3-4: Update NON_CHAT_MODEL_PATTERN and the mapApiRouteModel
discovery filtering to exclude media model IDs with gpt-image-, sora-, and veo-
prefixes. Add regression coverage confirming these IDs are omitted while
supported chat models remain discoverable.
- Around line 67-109: The curated fallback model entries in the API-Route model
catalog are stale and expose IDs that may not be supported; refresh these
entries from the current API-Route pricing catalog, or remove the non-default
entries so they are only available after authenticated discovery succeeds.
Update the model catalog definition containing the entries for claude-haiku-4-5,
gpt-4o-mini, gemini-2.5-pro, deepseek-chat, and qwen-max while preserving the
hybrid picker’s default behavior.

I found issues that need to be addressed before this is ready.

Merge readiness

• GitHub reports MERGEABLE, but BLOCKED / CHANGES_REQUESTED at 5530cd5. CodeRabbit is the only current-head check/status returned; its success does not establish build/test CI coverage. Resolve the review requests and obtain the required checks before merge.
• Synchronize with current main (d16318a). It is one unrelated xAI OAuth fix beyond this PR's merge base (e2b021d); there is no confirmed conflict or release-metadata drift.
• The CodeRabbit request to exercise the noncanonical request is not implemented in client.test.ts:939-954: it constructs the client without sending a request. Add the requested header assertion. Fresh noncanonical requests do withhold authorization; this is a missing regression assertion, not evidence of a leak in that scenario.
• Correct the PR summary's six-model curated list: this head retains only claude-sonnet-4-6. Removing the unsupported fallback entries, adding the media filters, and adding the metadata precedence/HTTP tests address those earlier requests.

Findings

Remediation scope: this is an additive gateway integration. Reuse the existing OpenAI-compatible transport, profile storage, startup flow and settings filters. Prefer adapting API Route's new descriptor/auth/env code to those contracts. Where needed, add only API Route entries to existing registration lists. The affected paths below describe behaviors to verify, not a requirement to edit every named function. No new profile system, persistence schema, routing abstraction, or repairs for other gateways are requested.

[P1] Make the new API Route configuration honor existing profile behavior

Descriptor contract: api-route.ts:89-94

Stated contract: #2212 requests “Support saved provider profiles and environment-based configuration”; the new test says “API Route preset uses the existing generic profile path”. Existing profile tests also require clearing managed provider environment when switching.

Root cause: the new API Route descriptor and env-handling choices do not fit the existing profile credential/model contract. A saved API Route profile puts its entered key only in OPENAI_API_KEY; dedicatedCredentialsOnly then rejects it with API Route auth is required. Set API_ROUTE_API_KEY. An ambient dedicated key instead wins over the selected profile's saved key. Its ambient model similarly wins over the saved model. Switching to an Anthropic profile leaves both dedicated variables behind, and the client selects API Route again.

Attribution: PR-activated. The same existing generic profile targeting the canonical URL authenticates at both merge base and current main; this head recognizes the endpoint as dedicated-only and rejects its saved key. The new env-intent resolver also makes previously inert uncleared variables select API Route.

The following existing paths expose the mismatch. A correction to the new gateway must work across them; they are not a prescribed file-edit checklist:

Author fix: make API Route use the existing profile credential/model contract. Prefer correcting the new descriptor and API Route-specific auth/env handling; add minimal API Route registrations only where the existing contract requires them. A saved profile must authenticate with its selected key/model, work after restart, and stop controlling requests when switched away. Preserve credential ownership and the canonical endpoint boundary. Verify those outcomes with saved-only and competing-ambient-state regressions. The table does not require a new dedicated persistence path or edits to every helper; the exact mechanism is open, and the shared profile/transport framework should remain intact.

[P1] Include the new routing variables in the host-managed settings boundary

New route selector: routeMetadata.ts:1091-1098

Stated contract: the existing managedEnv.test.ts test “preserves the complete host-managed Command Code route against settings env” requires OpenClaude configuration to preserve host-owned routing when CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST is set.

Root cause: isProviderManagedEnvVar recognizes neither API_ROUTE_API_KEY nor API_ROUTE_MODEL. Both pass through withoutHostManagedProviderVars. With the host selecting Anthropic and OpenClaude’s own global config.env supplying an API Route key, applyConfigEnvironmentVariables changes the route to API Route despite the host flag. The model variable can likewise override a host-selected API Route model.

Attribution: PR-activated. The same OpenClaude global-config merge stays on Anthropic at merge base and current main; the new key-only selector activates it on this head. This does not depend on Claude Code’s .claude directory or its removed settings source.

In this PR: hasApiRouteEnvOnlyProviderIntent introduces the key-based selector; getAllowedApiRouteConfigModel and client defaults consume the model; descriptor/preset metadata publishes both inputs. Both trusted-source/pretrust and post-trust settings merges depend on the existing host filter.

Author fix: register both new names with the existing host-managed classifier and test the host boundary through both settings-merge entrypoints. Keep settings trust policy and old provider behavior unchanged; do not broaden this into repairing unrelated providers' allowlists.

[P2] Preserve API Route env-only intent before applying a legacy startup profile

Env-only registration: routeMetadata.ts:1168-1170

Stated contract: the new README row offers API_ROUTE_API_KEY setup. The existing startup suite explicitly tests that env-only provider selection takes precedence over a saved profile (buildStartupEnvFromProfile preserves Concentrate env-only setup over a saved profile).

Root cause: the new resolver recognizes API Route, but the separate hasConcreteProviderSelection guard in providerProfile.ts omits its key. With API_ROUTE_API_KEY exported and a valid legacy OpenAI profile saved, the real startup wrapper successfully applies that profile, setting OPENAI_BASE_URL=https://api.openai.com/v1. The conflicting URL then prevents API Route's new client defaults from running. A valid default-gateway credential can produce the same override. A fresh setup with no valid fallback does not reproduce this successful overwrite.

Attribution: PR-introduced integration omission: API Route env-only selection is new, and its earlier startup guard does not recognize it.

In this PR: the new route-intent function, client defaults, model/default logic and direct client/validation tests depend on this entrypoint. The plural-profile guard already calls the generic env-only resolver; the legacy/fallback guard does not.

Author fix: honor API Route's new env-only selection in the existing startup guard and add an actual applyStartupEnvFromProfile regression with a valid saved fallback. Cover dedicated model and descriptor-default selection. Preserve explicit conflicting endpoints/provider flags and other providers' precedence.

[P2] Admit both API Route setup variables through --provider-env-file

New setup example: .env.example:219-223

Stated contract: README:162 directs users to “export them explicitly or run openclaude --provider-env-file .env for provider/setup variables.”

Root cause: the new dedicated variables are missing from envFile.ts's ALLOWED_ENV_FILE_KEYS. Loading either API_ROUTE_API_KEY=... or API_ROUTE_MODEL=... throws Unsupported variable ... in --provider-env-file. The CLI exits before applying --provider, so adding --provider api-route cannot recover this setup path.

Attribution: PR-introduced integration omission. The PR publishes these new provider inputs without admitting them through the existing documented loader.

In this PR: .env.example adds the dedicated key, README and website list dedicated key/model setup, and descriptor/generated preset metadata declares both. Check both fields together; the generic OPENAI_MODEL example does not eliminate support for API_ROUTE_MODEL.

Author fix: add both names to the existing explicit setup allowlist and test the real loader, preserving existing-value precedence and atomic rejection of unsupported variables. Keep the parser and security restrictions intact; do not replace the allowlist with a broad prefix.

[P2] Isolate the new provider-flag tests' dedicated environment state

New suite: providerFlag.test.ts:1852-1865

Stated contract: the new test “sets API Route OpenAI-compatible defaults and mirrors API_ROUTE_API_KEY” asserts the descriptor default, using the suite's existing environment reset/restore convention.

Root cause: the new cases mutate API_ROUTE_API_KEY and API_ROUTE_MODEL, but neither appears in ENV_KEYS or RESET_KEYS. The default test fails when run alone with API_ROUTE_MODEL already set: expected claude-sonnet-4-6, received the inherited model. Filtered runs can also leave their dedicated state behind. The final switch cases happen to clean it during a full-file run.

Attribution: PR-introduced test isolation failure. These new mutations/assertions do not exist at merge base or current main.

In this PR: both variables need the flag suite's save/reset/restore lifecycle. The changed client, model and validation suites already register both and were checked.

Author fix: include both names in this suite's existing isolation lists; verify the complete suite and a filtered default test with a seeded API_ROUTE_MODEL. Do not change production model precedence or the shared test framework to make the assertion pass.

Configuration and validation scope

The new fields cross these surfaces; corrections should preserve their existing constraints:

Malformed catalog records, invalid URLs, credential placeholders and failed discovery use the existing mapping, validation and cache fallback paths. No new HTTP parser or framework is needed for these fixes. Keep README, .env.example and website setup claims aligned while implementing the accepted feature.

Validation: 480 focused tests and 661 broader provider/profile/discovery tests passed; 43 env-file/managed-settings tests passed. Root and website typechecks, generated integration consistency and the PR security scan passed. An additional CLI grouping had 91 passes and one built-CLI startup timeout reproduced on merge base. Live authenticated API Route requests were not tested. No duplicate API Route PR was identified; the gateway direction matches #2212.

I found issues that need to be addressed before this is ready.

Remediation scope (read first)

This PR is an additive provider integration. The expected fix is to register api-route on the same existing hooks the other OpenAI-compatible dedicated gateways already use—not to redesign profiles, routing, validation, or the OpenAI shim.

Do:

• Add api-route to existing guard unions / early-return exceptions (same shape as apismart/concentrate/llmtr/commandcode).
• In code this PR already added or touched (applyApiRouteEnvOnlyDefaults, api-route applyProviderFlag branch), mirror the one-line patterns siblings use (pool cleanup, usableProviderModelEnvValue).
• Add api-route rows to existing test suites by copying the apismart/concentrate withhold cases.

Do not:

• Refactor buildLaunchEnv, shared profile persistence, openaiShim, or validation targeting.
• Change canonical URL policy, credential schema, or unrelated gateways’ behavior.
• Introduce a new API Route–specific framework, persistence path, or routing layer.

If a fix would require editing unchanged core helpers beyond adding api-route to an existing list or || branch, stop and ask— that is out of scope for this PR.

Merge readiness

• [P1] Clear stale CHANGES_REQUESTED and re-review on current head (226808df)
  GitHub still shows reviewDecision: CHANGES_REQUESTED from the prior review at 5530cd5, while CodeRabbit approved 226808df. Earlier integration findings on this head look addressed; this review adds registration omissions for api-route on existing proxy-boundary hooks. Supersede the old request after verifying the new head.

• [P2] Confirm required CI beyond CodeRabbit for fork PRs
  gh pr checks currently reports only CodeRabbit success. Local validation passed (typecheck, focused tests, integrations:check, security:pr-scan); upstream merge policy may still expect pr-checks.

• Branch is mergeable and even with main (d16318a); no rebase drift.

Findings

[P1] Register API Route on the existing noncanonical proxy credential hooks

Attribution: PR-introduced omission (new route id), not a critique of the shared framework.

Stated contract: Existing tests already require keyless proxy relaunch to withhold ambient credentials—for example openai launch withholds ambient ApiSmart credentials from a keyless proxy profile on restart (and Concentrate / LLMTR / Command Code siblings). buildLaunchEnv comments describe the same rule.

Root cause: This PR wired api-route through routing/validation/client defaults but did not add api-route to the existing registration sites where apismart/concentrate/llmtr/commandcode already participate. No new mechanism is required—only the missing enum members.

What fails: Keyless api-route proxy relaunch can still leave ambient OPENAI_API_KEY / OPENAI_API_KEYS on a user-controlled proxy URL (repro on head; apismart same shape clears them). The env-only helper this PR added (applyApiRouteEnvOnlyDefaults) should apply the same pool cleanup peers get in launch guard when the base is noncanonical—still a local edit in that new function, not a shim change.

In this PR (registration + tests only):

Unchanged on main: Do not rewrite the guard logic—only extend the lists. Do not “fix” other providers.

Author fix: One focused commit: register api-route on all four rows above. Mechanism is prescribed only as “same as apismart/concentrate”; implementation stays copy-and-adapt.

Out of scope: openaiShim, validation framework, canonical policy, profile storage schema, unrelated routes.

[P2] Match the existing flag model one-liner in the api-route branch you already added

Attribution: PR-introduced (new case/branch in applyProviderFlag).

Stated contract: ApiSmart/Concentrate already assign models via usableProviderModelEnvValue in their flag branches; this PR added an api-route branch without that single call.

Root cause: Raw API_ROUTE_MODEL → OPENAI_MODEL copy in the new api-route flag block only.

What fails: Placeholder/whitespace model env pollution after --provider api-route (low severity; env/key placeholders are already tested).

Required correction: In the existing api-route flag block, use usableProviderModelEnvValue the same way as Concentrate/ApiSmart; add one providerFlag.test.ts case. No changes to model.ts precedence or global validation.

Author fix: One helper call + one test in files this PR already modified.

Out of scope: Model resolution redesign, new validation kinds, editing sibling providers.

Notes

Prior review integration work on this head (profile generic-key contract, host-managed vars, env-file allowlist, env-only startup precedence, client noncanonical request test) looks complete. Remaining work is parity registration for a new provider id on hooks that already exist—appropriate scope for a gateway PR.

Remediation scope (read first)

This PR is an additive gateway integration. Register api-route on the same existing hooks ApiSmart/Concentrate/LLMTR/Command Code already use in providerProfiles.ts, routeMetadata.ts, and the small mirrored-key list in requestExecutor.ts. Do not redesign profiles, the OpenAI shim, or canonical URL policy.

Findings

[P1] Register API Route on the existing plural-profile / startup hooks (ApiSmart parity)

Attribution: PR-introduced. This PR adds the api-route preset, providerProfiles.test.ts coverage, and proxy withhold tests on providerProfile.ts, but src/utils/providerProfiles.ts has zero api-route references while ApiSmart/Concentrate/LLMTR/Command Code stamp route identity, withhold retargeted credentials, and default canonical base URLs in the same functions.

Stated contract:

• retargeted ApiSmart profile withholds its dedicated credential expects CLAUDE_CODE_PROVIDER_ROUTE_ID to be 'apismart' after apply.
• retargeted ApiSmart profiles keep route identity but persist without their dedicated credential expects persisted CLAUDE_CODE_PROVIDER_ROUTE_ID: 'apismart'.
• openai launch withholds ambient API Route credentials from a keyless proxy profile on restart depends on route identity during relaunch (today’s tests hand-set CLAUDE_CODE_PROVIDER_ROUTE_ID in the persisted blob).
• README API Route row documents https://global.api-route.com/v1 (saved profiles with empty baseUrl must not leave OPENAI_BASE_URL blank — ApiSmart already backfills in normalizedProfileBaseUrl).

Root cause: New gateway id without the sibling registration rows in providerProfiles.ts. Proxy relaunch without a stamped route id skips isNoncanonicalApiRouteLaunch withholding and leaves ambient OPENAI_API_KEYS (verified: without CLAUDE_CODE_PROVIDER_ROUTE_ID pool survives; with 'api-route' it is cleared). Profile apply for retargeted/keyless api-route leaves CLAUDE_CODE_PROVIDER_ROUTE_ID unset (ApiSmart sets 'apismart').

In this PR (close together):

Unchanged on main: Do not rewrite profile storage or buildLaunchEnv logic — only extend lists/branches. providerProfile.ts proxy withhold hooks added in this PR are fine; this finding is the plural-profile layer.

Author fix: Add api-route rows mirroring ApiSmart/Concentrate in providerProfiles.ts (helper + stamp + withhold + default base URL + discovery skip). Copy the apismart proxy persistence/relaunch tests for api-route without manually injecting CLAUDE_CODE_PROVIDER_ROUTE_ID in fixtures. One commit closing every row above.

Out of scope: Changing dedicatedCredentialsOnly, removing OPENAI_API_KEYS fallback, or refactoring openaiShim.

[P2] Honor the existing CLAUDE_CODE_USE_OPENAI=0 env-only opt-out for API Route

Attribution: PR-introduced (hasApiRouteEnvOnlyProviderIntent).

Stated contract: routeMetadata.test.ts — resolveActiveRouteIdFromEnv({ CLAUDE_CODE_USE_OPENAI: '0', CONCENTRATE_API_KEY: … }) must not be 'concentrate'.

Root cause: hasApiRouteEnvOnlyProviderIntent omits Concentrate’s CLAUDE_CODE_USE_OPENAI guard. With API_ROUTE_API_KEY set and CLAUDE_CODE_USE_OPENAI=0, resolveActiveRouteIdFromEnv still returns 'api-route', so env-only setup can force the OpenAI shim despite an explicit OpenAI opt-out.

In this PR: routeMetadata.ts intent helper; add the negative case beside the Concentrate test in routeMetadata.test.ts.

Author fix: Add the same CLAUDE_CODE_USE_OPENAI clause Concentrate uses; extend routeMetadata.test.ts with the api-route analogue.

Out of scope: Changing global OpenAI opt-out semantics for other routes.

[P2] Add API Route to the mirrored dedicated-key list in requestExecutor.ts

Attribution: PR-introduced (new mirror path for API_ROUTE_API_KEY).

Stated contract: openAIApiKeyIsCopiedProviderKey already lists APISMART_API_KEY, CONCENTRATE_API_KEY, LLMTR_API_KEY, etc., so mirrored OPENAI_API_KEY values are classified consistently when dedicated env vars match.

Root cause: API_ROUTE_API_KEY is missing from that array while providerFlag.ts / client.ts mirror it into OPENAI_API_KEY on canonical selection.

In this PR: src/services/api/openaiShim/requestExecutor.ts (~317–337) only.

Author fix: Append requestProcessEnv.API_ROUTE_API_KEY to the same list; add a focused test if an existing copied-key test file covers siblings.

Out of scope: Reworking shim credential selection.

Notes

• Focused validation on head: integrations:check, root typecheck, and 802/803 tests in the API Route–related files (one providerProfile.test.ts case failed here only due to sandbox EACCES writing ~/.openclaude, not product logic).
• Prior Greptile/CodeRabbit/jatmn items on model precedence, env-file allowlist, host-managed vars, env-only startup precedence, and providerProfile.ts proxy registration appear addressed on e610e8e4; remaining gap is providerProfiles.ts sibling registration plus the small guards above.
