Create a schema for code-quality telemetry
$0.05 USDC maxCalculate deterministic code metrics, then infer a JSON Schema that consumers can use for build reports, dashboards, or regression history.
Inspect the 2-step recipeCode metrics
Measure caller-supplied source code with Python AST analysis or a deterministic lexical fallback, including per-function complexity, a SHA-256 fingerprint, density ratios, syntax status, and actionable maintainability signals without retaining or forwarding the code.

Endpoint
https://apiacre.com/v1/developer/code-metricsSend the JSON body below. An unpaid request returns HTTP 402 with a PAYMENT-REQUIRED header; an x402-compatible buyer signs the requirement and retries with PAYMENT-SIGNATURE.
Pay $0.025 USDC and run in your browserOfficial Coinbase agent path
Coinbase Agentic Wallet can satisfy this x402 request in one command. Running it may pay automatically, so --max-amount is fixed to $0.025 USDC in atomic units. Copying the command does not install, authenticate, sign, or pay; review the request and use a separate low-value wallet before running it.

}Complete recipes using this API
These buyer-controlled recipes connect this service to compatible API Acre results. Every step has its own exact price and requires separate authorization.
Generate and statically review OpenAPI tests
$0.125 USDC maxGenerate deterministic pytest smoke tests from a caller-supplied OpenAPI 3 document, then measure the generated Python source before retaining or running it. The workflow validates syntax and static quality signals; it does not execute tests or contact the target API.

These optional follow-ups use this result in a larger workflow. Each call shows a fresh x402 challenge and requires separate buyer authorization.
