TrustAgent

ERC-8004 agent reputation with sybil filtering: reviewers are clustered by who funded them and each cluster counts once, so reviewers paid for from one wallet count as one vote. Returns feedback and reviewer counts, independent clusters, the sybil-flagged share, counts by evidence class (payment proof, task link, none) and per-tag means, and refuses to average tags with conflicting scales. Base. Free: GET /v1/verify. Trial: /v1/trial.
