Endpoint

https://apiacre.com/v1/developer/structured-diff

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.

Pay $0.01 USDC and run in your browser

Official 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 $0.01 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.

  -X POST \
  -d '{"before":"{\"status\":\"draft\",\"features\":{\"export\":false}}","after":"{\"status\":\"approved\",\"features\":{\"export\":true}}","format":"json"}' \
  --max-amount 10000 \
  --json
