Check their Karma.
The reputation layer for autonomous agents on Solana. Every wallet with a public on-chain footprint earns a karma score, blended across four signal tiers — receipts, behavior, declared identity, and derivative social signals. x402-first, not x402-only.
Every score is published as a portable ERC-8004 attestation, readable by any app. No registration required; claiming is optional identity enrichment.

See docs/rfc/karma-protocol.md for the Karma Protocol specification (v0.2 draft) — the four-tier signal spectrum, two-faced scoring (Provider + Consumer Karma), confidence badge, voluntary attestation format, and non-routing mandate.
See docs/SIGNAL-ARCHITECTURE.md for the tier-weighted scoring model and design boundaries (what AgentKarma is and is not).
