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.

Quality grade

How grading works

C 43.3 / 100

Availability 40.0 / 40

Endpoint responded (HTTP 200)

Payability 3.3 / 20

✗ Answers a real HTTP 402 challenge
✓ Publishes a /.well-known/x402 descriptor
✗ Payment address on record
✗ Settlement network declared
✗ Price declared

Demand 0.0 / 40

No payment address on record, so demand cannot be measured

Owner verified 0.0 / 3

Nobody has claimed this listing yet

Endpoint last checked 6 h ago. Availability and on-chain demand are both re-probed daily; the grade updates automatically on the next pass. This grade sets search order and leaderboards; the readiness score below is shown for reference only.

x402 readiness

D · 52/100

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 C, 43.3/100), which weighs availability, payability and on-chain demand. How the two differ

Valid payment requirements	0/10	No payment requirements on record.
Live 402 challenge	4/25	Endpoint answers, but we have not seen a 402 challenge (2677 ms); slow response -1.
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	16/16 probes succeeded over 30 days (100%).
Resource declaration	10/10	Declares 10 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: Slow (2677 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Payment evidence: x402_manifest — We read the seller's own /.well-known/x402 descriptor. Also: 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. Display only: search order uses the quality grade.
