Demand 13.7 / 35
8 distinct payers, 236 USDC transfers in the last 30 days; discounted because most transfers come from few payers

x402 readiness

B · 88/100

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 A, 71.8/100), 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 (226 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 10/10 Declares 4 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 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 75 points, scaled to 100.
Responsiveness: Responsive (226 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, 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.

Where it loses the most points, and how to win them back

  • Verified identity −5 — Claim the listing and prove control of its domain.
    Now: Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control.
  • Freshness + modern flags −4 — Keep the listing current in the registry or source it comes from.
    Now: not seen in a source for over 30 days; declares x402.

POST https://api.forum-labs.com/v1/trust/score $0.0050 / call

Endpoint trust/QoS score for an x402 endpoint BEFORE you pay it. Given an endpoint url (and optional method), returns a mechanical reliability score (0-100) and verdict (reliable/mixed/unreliable/unrated) from longitudinal probe history: availability, latency percentiles, payment-terms stability, an

POST https://api.forum-labs.com/v1/trust/report $0.0200 / call

Deep endpoint trust/QoS report for an x402 endpoint. Everything the trust score returns PLUS history detail: the full payment-terms drift log (including custody/payTo changes), the discovery/listing timeline across directories, the paid-delivery sample log, and a summarized counts-by-outcome breakdo

POST https://api.forum-labs.com/v1/safety/screen $0.0100 / call

Pre-trade token safety screen. Given a token mint/address (and chain), returns a creator-reputation verdict (safe/caution/danger/unknown) and a 0-100 score (higher = safer) derived from the deployer's on-chain launch-abandonment track record — BEFORE an agent trades the token. Honest `unknown` when

Deep pre-trade token safety screen. Everything the basic screen returns PLUS the deployer-cluster serial-abandonment evidence block: prior launches and abandonment counts/rates at BOTH the wallet AND the funding-graph cluster level, the cluster id, scan coverage, and qualifier notes — the reason to
