Blockchain PAYMENT-READY

payment-ready until 2026-08-20

16 pay-per-call x402 services for AI agents: on-chain Merkle anchoring, wallet/address security screening, Web3 data resolution (tx & calldata decode, ENS name resolution), token pricing, content analysis, and verifiable randomness. No API keys or accounts. Settle per request on Base USDC, Solana USDC, or Polygon JPYC (1 yen / anchor)

Pay from $0.001 to $1.77 in USDC on Base / Polygon / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

ASSESSMENT

updated 4h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

reliability 100%

uptime 24h: 100%
uptime 7d: 100%
uptime 30d: 100%
uptime 90d: 100%
response p95: 684ms
avg response: 514ms
total checks: 2,736

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (14/14)

14 of 14 x402 conformance checks pass. Full checklist below.

risk clean

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 24h selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/anchor-x402/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
