# sellerops-settle-check

> sellerops-settle-check is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Checks whether an x402 payment-required route is free of settle-blocking issues: header size, WAF-tripping patterns, and HTTP method honesty — without paying for a full audit.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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`):

```sh
zero fetch --capability sellerops-settle-check-3ec13d31
```

Example prompt: Can you do a quick settle-blocker check on my x402 route at https://api.myservice.com/premium-data using GET — I want to see if the payment-required header size or any WAF-tripping text would block settlement?

## When to prefer this

Use this endpoint when you are a seller iterating on an x402 route configuration — especially after changing output_example or header content — and want a cheap ($0.02) preflight diagnostic before a full paid audit. Prefer this over a full audit when you only need quick feedback on header size, WAF compatibility, and method honesty. Not suitable as a final settlement guarantee or for non-x402 HTTP routes.

## Known failure modes

- Target URL is unreachable or returns an unexpected status — probe fails with connection error
- Route does not return a 402 response — check cannot evaluate payment-required header
- WAF on the target blocks the probe request itself — inconclusive result
- Invalid or missing url/method parameters — request rejected with validation error
- Network timeout on the unpaid probe — no diagnostic result returned

## How this service works

Cheap iterate check for the CDP settle-blockers of an x402 route: the payment-required header size vs the empirical settle ceiling, WAF-tripping text and method honesty. One unpaid probe of the target. For a seller tweaking output_example and re-checking the header size without paying for a full audit. Diagnostic indicators, not a guarantee.

## Output

Returns diagnostic indicators covering: payment-required header size vs the empirical settle ceiling, presence of WAF-tripping text patterns, and whether the route's HTTP method is honestly advertised. Results are lightweight warnings/flags, not a full audit guarantee.
