nsgoods Agent Trust & Screening Oracle

AI PAYMENT-READY

payment-ready until 2026-08-20

nsgoods, the verifiable trust layer for AI agents. Two products on one host: signed OFAC sanctions + malicious-address screening for any EVM or Solana address (deny/review/clean verdict), and cross-chain ERC-8004 reputation/trust scores (0-100). Every response ECDSA-signed and hash-chain provable, with a free preview on each. Part of a 6-oracle suite (aggregated manifest at https://x402.nsgoods.org/.well-known/x402).

Pay from $0.005 per request in USDC on Base, 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: 99.8%
uptime 30d: 100%
uptime 90d: 100%
response p95: 533ms
avg response: 542ms
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/nsgoods-agent-trust-oracle/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.
