How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object with the SKU identifier ('facdiscovery'), a human-readable title, the price per call, and discovery match metadata for the queried payTo address or resource URL as indexed by the OpenX402 facilitator.
Example use cases
Diagnose wallet discovery coverage
“How many times has my payTo address 0xAbC123... shown up in the OpenX402 facilitator discovery index? I want to know if the facilitator is picking me up correctly.”
Audit resource URL discoverability
“Can you check the facdiscovery endpoint and tell me how many matches exist for my resource URL https://myapi.example.com/api/data in the OpenX402 facilitator?”
Debug missing x402 payments
“I think the OpenX402 facilitator isn't routing payments to my endpoint. Can you run a facilitator discovery lookup for both my payTo address 0xDef456... and my resource URL https://myapi.example.com/premium to see if either is being matched?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/facdiscovery?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to inspect or audit facilitator discovery data within the OpenX402 ecosystem — for example, when debugging why a wallet address or resource URL is not being matched or paid through the x402 protocol. This is narrowly scoped to OpenX402 facilitator diagnostics and is not a general-purpose x402 payment or settlement tool.
Side effects
- HTTP 402 returned if payment header (EIP-3009) is missing or invalid — includes payment details needed to settle
- Invalid or malformed payTo address returns empty match count or validation error
- Unknown resource_url returns zero matches without error
- Unsupported HTTP method (e.g. POST) returns 405
- Facilitator base URL override pointing to non-OpenX402 server may return unexpected results
