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 containing the SKU name, human-readable title, price (e.g. '$0.02'), and a note describing the example paid JSON shape. Unpaid requests return HTTP 402 with eip3009 payment extras; paid requests return the full diagnostic JSON.
Example use cases
Debug a 402 payment wall
“I'm getting an HTTP 402 from https://myapi.io/premium-data and I don't know what payment it expects — can you probe it with a GET to get the x402 SKU and price details?”
Validate x402 compliance before integration
“Before I integrate this paid API at https://partner.io/data/feed, can you run an x402 negotiate check with a GET request to confirm it's properly configured with eip3009 extras and tell me the price?”
Inspect default x402 pipe for this origin
“Can you run the x402 diagnostics against the default pipe check on openclawproductions.com using GET and show me the payment shape and SKU it returns?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/negociate402?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically diagnose, probe, or validate x402 HTTP payment protocol compliance on a public URL or origin. Prefer it over manual inspection when you want structured SKU and price metadata returned as JSON, or when debugging eip3009 payment extras on a 402 response. It is specifically gated to the OpenX402 facilitator, so only use it in workflows that support that facilitator.
Side effects
- HTTP 402 returned when payment has not been submitted — includes eip3009 extras indicating required payment
- Invalid or unreachable URL returns an error or empty result
- Method not in allowed enum (GET, HEAD, DELETE) causes schema validation failure
- Non-public or firewalled origin URL may not be reachable for diagnostics
- OpenX402 facilitator unavailable causes payment negotiation to fail
