 `blockrun_rpc` POSTs a standard JSON-RPC 2.0 body to `/v1/rpc/{network}`. Flat **$0.0040 per call** ($0.002 base + the $0.002 transaction fee). A JSON-RPC **batch array charges per element but pays the flat fee only once** — $0.002 × n + $0.002, so a batch of 3 costs $0.0080 where three separate calls cost $0.0120. Batch whenever you can. Settlement in USDC via x402. Responses are cached briefly server-side for identical read calls (`X-Cache: HIT` is free of upstream latency but still billed).
