feat(gateway): add API Route hybrid gateway - #2225
DennyHo0917 wants to merge 2 commits into
Conversation
Add API Route as a descriptor-first OpenAI-compatible aggregating gateway with hybrid catalog discovery, dedicated API_ROUTE_API_KEY credentials, and route boundary protections.
📝 WalkthroughWalkthroughChangesAPI Route is added as an OpenAI-compatible gateway. The integration includes model discovery, dedicated credentials, canonical URL checks, provider metadata, model selection, validation, tests, and setup documentation. API Route gateway
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~45 minutes Change: Feature Suggested reviewers: Merge Risk: 🟡 Moderate · up to The new gateway lacks a regression test proving that a noncanonical endpoint receives no authorization header, and its provider tests can inherit API Route settings across cases. Add the focused request assertion and environment cleanup before merging. 🚥 Pre-merge checks | ✅ 5 | ❌ 2❌ Failed checks (2 warnings)
✅ Passed checks (5 passed)
Full details: Risk Surface DisclosedExplanation The PR touches authentication, provider routing, outbound model discovery, startup probing, and background refresh. The description discloses credential-boundary risk, but it does not explicitly assess the full risk surface or state whether a blocker exists. The existing review comment identifies a credential-leakage test gap, and the final noncanonical API Route test still checks only environment state without sending a request or asserting that the Authorization header is absent. Therefore, blocker status remains unresolved. Resolution Add an explicit risk and blocker assessment covering authentication, credential withholding, outbound discovery, startup probing, and background refresh. Resolve the credential-boundary review item by issuing a noncanonical request in the test and asserting that the Authorization header is absent, then state whether any remaining issue blocks merge.

Greptile SummaryThis PR adds API Route as a descriptor-first, OpenAI-compatible aggregating gateway with curated and dynamically discovered models, dedicated credential handling, route-boundary protections, generated integration metadata, tests, and user-facing documentation.
Confidence Score: 4/5The PR is not yet safe to merge because its documented env-only model configuration does not control the model used by runtime requests. API Route can be activated with its dedicated key, but no corresponding env-only defaults handler copies Files Needing Attention: src/integrations/gateways/api-route.ts, src/integrations/gateways/api-route.test.ts
|
| Filename | Overview |
|---|---|
| src/integrations/gateways/api-route.ts | Defines the gateway, curated catalog, discovery mapper, and preset, but advertises an env-only model variable that runtime request resolution does not consume. |
| src/integrations/routeMetadata.ts | Adds API Route intent detection, canonical URL checks, route resolution, and dedicated credential withholding. |
| src/integrations/gateways/api-route.test.ts | Covers descriptor metadata, credential boundaries, discovery mapping, and route detection, but not env-only runtime model selection. |
| src/integrations/providerUiMetadata.ts | Recognizes the dedicated API Route credential and correctly resolves preset UI metadata. |
| web/src/data/providers.ts | Adds API Route to the website’s provider catalog. |

When API Route is activated through API_ROUTE_API_KEY without a saved provider profile, this preset advertises API_ROUTE_MODEL, but the runtime env-only path has no API Route defaults handler and model selection reads only OPENAI_MODEL. As a result, API_ROUTE_MODEL and the declared claude-sonnet-4-6 default are ignored, so requests may use an unrelated OPENAI_MODEL value or fall back to gpt-4o.

- 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.

Exercise the noncanonical request before asserting the credential boundary.
The test leaves API_ROUTE_API_KEY in process.env and checks only that OPENAI_API_KEY is undefined. createOpenAIShimClient can hydrate compatibility credentials, and executeOpenAIRequest resolves route credentials while building headers. Construction alone does not prove that the request omits Authorization. Invoke client.messages.create for claude-sonnet-4-6, capture the fetch headers, and assert that authorization is absent.
