Paid verification

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

A 81.2 / 100

Availability 20.0 / 20

Endpoint responded (HTTP 200)

Payability 15.0 / 15

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

Demand 24.0 / 35

258 distinct payers, 800 USDC transfers in the last 30 days; the wallet is shared by 2 listings, so each is credited 1/2

Performance 10.0 / 10

Last probe answered in 125 ms (full marks at 200 ms or less)

Readiness 12.2 / 15

Agent readiness 81/100

Owner verified 0.0 / 5

x402 readiness

B · 81/100

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 A, 81.2/100), 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	20/25	Endpoint reachable; its 402 challenge was seen earlier (125 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	8/10	8 paid resources; 8 sampled lack a description.
Verified identity	5/10	Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control.
Freshness + modern flags	3/5	seen within 30 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 (125 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. 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. It also feeds 15 points of the x402 quality grade.

What we measured

Over the last 30 days we probed this API 32 times on 30 days; it answered 32 (100%). Median response 135 ms, 95th percentile 328 ms.

On-chain, 258 distinct wallets paid its payment address 800 times in the last 30 days.

Among the 10,130 reachable x402 APIs in our snapshot of 2026-11-13 01:12 UTC, it is faster than 84% and higher on readiness than 58%.
