## 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 vealth-x402-fix-openapi-patcher-201ecbc3 -d '<json body>'
```

Example prompt: Can you fix the x402 protocol fields in my OpenAPI spec at https://myapi.example.com/openapi.json so it uses the correct object format instead of plain strings?

## When to prefer this

Choose this endpoint when you need to automatically detect and repair x402 payment protocol field format errors in an existing OpenAPI spec — specifically when the protocols field incorrectly declares x402 as a plain string rather than a structured object. Prefer this over manual spec editing when you want a deterministic, programmatic diff of required changes.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint may return an error or empty todos list
- URL does not point to a valid OpenAPI spec — changes_applied may be empty or misleading
- x402 fields already correct — returns empty changes_applied with no-op result
- Malformed JSON at the target URL — may fail to parse and return an error
- Payment not settled — x402 $1 USDC payment required before response is returned
