47620 — x402 Solana Payment Gateway + Pay-per-call Data API

https://47620.xyz/mcp/trust/%7Btarget%7D

● healthy ai

Non-custodial x402 payment gateway on Solana (1% on-chain fee) plus a pay-per-call Solana data API for agents: token price, account balances, tx lookup, trending DEX pairs, network health. No signup, no API key — pay USDC per call.

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

B+ 69.9 / 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 13.5 / 35

38 distinct payers, 1197 USDC transfers in the last 30 days; the wallet is shared by 5 listings, so each is credited 1/5; discounted because most transfers come from few payers

Performance 7.4 / 10

Last probe answered in 671 ms (full marks at 200 ms or less)

Readiness 14.0 / 15

Agent readiness 94/100

Owner verified 0.0 / 5

x402 readiness

A · 94/100

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 B+, 69.9/100), 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 (671 ms).
x402 version	10/10	Speaks x402 v2.
Signed descriptor	n/a	No x402 standard defines a signed descriptor.
Uptime (30 days)	14.53/15	31/32 probes succeeded over 30 days (97%).
Resource declaration	10/10	Declares 191 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 85 points, scaled to 100.

Responsiveness: Responsive (671 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, 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.
