x402 readiness

A · 93/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here A, 73.0/100), which weighs availability, payability and on-chain demand. How the two differ

Valid payment requirements 10/10 Payment requirements carry a payee, a mainnet network and a price.
Live 402 challenge 25/25 Paid endpoint answers with an HTTP 402 challenge (146 ms).
x402 version n/a x402 version not observed yet.
Signed descriptor n/a No x402 standard defines a signed descriptor.
Uptime (30 days) 15/15 32/32 probes succeeded over 30 days (100%).
Resource declaration 10/10 Declares 17 paid resource(s).
Verified identity 5/10 Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control.
Freshness + modern flags 5/5 seen in a source within 7 days; declares x402.
Security declaration n/a Payment is the access control for an x402 resource.
Applicable criteria total 75 points, scaled to 100.
Responsiveness: Responsive (146 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).
Payment evidence: x402_challenge — We sent a request and got a live HTTP 402 challenge. Also: x402_manifest, bazaar_feed, catalog_listing. Qualifies the payment claim; adds no points.
Measured 2026-11-11.
Nine criteria, the same as the A2A readiness score, read from our daily probe of the paid endpoint, its payment requirements and 30-day probe history. Signed descriptor and security declaration are n/a for x402 (payment is the access control), as is an x402 version we have not observed; the remaining points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. It also feeds 15 points of the x402 quality grade.
