agent checkout x402_url handling and settlement verification procedure: Coinbase
Output
A structured JSON response containing a prose decision procedure brief (the 'brief' field) tailored to x402 URL handling and Coinbase settlement verification, along with metadata including the service slug, generation source (llm/reasoning/deterministic), model used, ISO-8601 generation timestamp, and payment confirmation details indicating whether the call was paid and settled.
Example use cases
Agent x402 checkout flow walkthrough
“My agent keeps hitting 402 responses during checkout — can you get me the full Coinbase decision procedure for handling x402 URLs so it knows exactly what to do next?”
Settlement confirmation after x402 payment
“After my agent pays via x402, how should it verify that the Coinbase settlement actually went through? Pull the procedure brief so I can wire it into the post-payment step.”
Building a safe autonomous payment loop
“I'm building an agent that autonomously processes x402 payments via Coinbase — fetch the decision procedure so I can make sure the checkout URL handling and settlement verification logic is correct before I deploy.”

Choose this endpoint when your agent needs a structured, LLM-generated decision procedure specifically for x402 payment URL handling and Coinbase settlement verification — not just raw protocol docs.

Side effects
- Missing or invalid 'method' or 'type' fields in input returns a 400-level validation error
- Payment not included or insufficient USDC causes a 402 response requiring the agent to pay before retrying
- Service temporarily unavailable returns a 5xx error
- LLM generation failure may return ok:false with an empty or absent 'brief' field
- Topic override parameter ignored silently if not a recognized slug
