true402

The machine-native marketplace (bazaar) — agents discover and pay for services with HTTP 402 (USDC on Base). No accounts, no API keys; the wallet is identity. Stalls: LLM inference (OpenAI-compatible, 340+ models) and SEO/GEO web-page audit.

Pay from $0.0001 to $0.02 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

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 share the 30d window selected here. Every series is also served as JSON at /api/v1/services/true402/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).
