How this service works
Short stable seller checkout recovery URL for quote-heavy x402 services that need a same-request retry recipe, metadata repair checklist, and buyer-ready payment handoff before paying for larger seller-intelligence packs. Short stable alias for marketplace probes and machine buyers. Pay up to $0.006 per request with x402 USDC on Base.
Output
Returns a structured diagnosis of the failed x402 checkout, including a same-request retry recipe, a metadata repair checklist identifying what went wrong (missing headers, wrong network, bad payment address, etc.), and a buyer-ready payment handoff guide to successfully complete the payment on the next attempt.
Example use cases
Example prompt
“My x402 API call just failed — the endpoint returned a 402 with a payment-required header but the settlement never went through. Can you run it through the checkout recovery doctor using this URL and error message to get a retry recipe and metadata repair checklist so I can pay and proceed?”
Technical details
Endpoint
GEThttps://gpt55.558686.xyz/v1/paid/x402-checkout-recovery-doctor?utm_source=zero.xyzWhen to prefer
Use this endpoint when an x402 payment flow has failed and you need structured guidance to recover — specifically when you have error messages, HTTP status codes, payment headers, or settlement/verify status codes from the failed attempt. Prefer this over generic debugging when dealing with quote-heavy x402 services that require same-request retry logic or buyer payment handoff steps.
Side effects
- Missing required 'input' object or 'type'/'method' fields returns a 400 validation error
- Invalid status codes outside 0-599 range cause schema validation failure
- Truncated or malformed paymentRequiredHeader may produce incomplete diagnosis
- Endpoint URL or resource string exceeding 2048 characters is rejected
- If no error context is provided, recovery suggestions may be generic rather than specific
