Code change review

Endpoint

https://apiacre.com/v1/developer/code-change-review

Send 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.

Agent one-call path

Optional third-party AgentCash can inspect this route and handle the x402 retry. Its fetch command may automatically pay, so this example caps the call at exactly $0.05 USDC. Copying the command does not pay; review the local wallet and request before running it.
