## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

zero fetch --capability xrpl-settlement-verification-for-agent-payments-via-x402-facilitator-1ca14b28
```

Example prompt: Give me a blunt decision procedure for verifying XRPL settlement on an x402 facilitator payment — I need the inputs to check, confirmation thresholds, and what failure modes to handle if the transaction doesn't clear.

## When to prefer this

Choose this endpoint when an agent needs a structured, actionable decision procedure for verifying XRPL settlements in x402 payment flows and free documentation does not provide a deterministic verification schema with failure modes. Best for agents that must make autonomous payment acceptance decisions on XRPL without human review.

## Known failure modes

- Payment not made or insufficient balance results in HTTP 402 with no procedure returned
- Invalid or missing required 'input' object causes schema validation error
- LLM generation failure may return ok:false in the result object
- Topic override may produce off-scope or low-quality procedure if unrelated to XRPL/x402
- Rate limiting or upstream model unavailability could cause timeout or error response
