Paid verification

How it works

No sponsored paid call yet.

Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.

x402 readiness

F · 36/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. For x402 and A2A listings it contributes up to 15 of the 100 quality points; for MCP listings it is shown for reference only. Search order and leaderboards use the separate quality grade (here D, 18.7/100), 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	0/27 probes succeeded over 30 days (0%).
Resource declaration	10/10	Declares 4 paid resource(s).
Verified identity	0/10	No /.well-known/x402 descriptor, OpenAPI document or owner declaration on record.
Freshness + modern flags	1/5	not seen in a source for over 30 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: x402_challenge — We sent a request and got a live HTTP 402 challenge. Also: catalog_listing. Qualifies the payment claim; adds no points.

Measured 2026-11-13.

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.
