SYNTHORA Agent Capability Attestation
Verification importedimported from the x402 Bazaar, not submitted by the operator · own this service? claim it
Paid API that evaluates an AI agent's declared capabilities against supplied sample outputs using multiple LLMs, returning a 0-100 reliability score, a trust tier and a per-capability verdict in an Ed25519-signed response.
Pay from $0.001 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.

Attributed pro-quota: this payout address is shared, so volume and buyers are the operator-level figure divided by the services sharing it. A declared convention, not an individually observed measure, and still a conservative undercount.
Top buyer share is a concentration signal, not part of the ranking score.

RECENT CHECKS
OVER TIME
All charts share the 90d window selected here. Every series is also served as JSON at /api/v1/services/synthora-agent-capability-attestation/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.
Shared payout address (64 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 65 services sharing it: a declared convention, not an individually observed measure.
