How this service works

Find useful work. Build a life from it. Every job shows the place, the task, the proof, and the pay before you begin. Start today and grow toward mastery.

Output

Returns a JSON object containing: a list of changes applied (e.g. field type corrections from string to object for x402), an install note describing where to serve the fixed spec, a list of remaining todos, the origin URL, and a product identifier string.

Example use cases

Fix API spec for x402 compliance

“My API at https://myservice.com/openapi.json has x402 listed as a plain string in the protocols field — can you patch it to use the proper x402 object format so it works with payment infrastructure?”

Prepare new API for monetization

“I just built an API at https://devapi.example.com and want to add x402 payment support — can you analyze the spec and tell me what changes to apply to my openapi.json to make it x402-ready?”

Diagnose x402 spec errors before launch

“Before I launch my API at https://api.myproject.io, can you check whether my OpenAPI spec has any x402 protocol field issues and give me the exact fixes to apply?”

Technical details

Endpoint

POSThttps://vealth.net/.well-known/vealth/x402-fix

When to prefer

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.

Side effects

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
