x402 readiness

D · 41/100

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 D, 20.2/100), 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 0/25 Endpoint did not answer.
x402 version 10/10 Speaks x402 v2.
Signed descriptor n/a No x402 standard defines a signed descriptor.
Uptime (30 days) 0/15 0/28 probes succeeded over 30 days (0%).
Resource declaration 10/10 Declares 67 paid resource(s).
Verified identity 0/10 No /.well-known/x402 descriptor, OpenAPI document or owner declaration on record.
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 85 points, scaled to 100.
Payment evidence: catalog_listing — A third-party catalog says it accepts payment. Qualifies the payment claim; adds no points.
Measured 2026-11-12.
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. Display only: search order uses the quality grade.
