How this service works

Reputation intelligence for the autonomous agent economy. Trust scores, Sybil detection, and cross-chain identity for 130,000+ ERC-8004 agents across 20 chains. Powered by x402 micropayments.

Output

A JSON object containing the agent's name, chain-qualified agentId, overall trustScore (0-100), and three component scores: scoreProfile (identity/profile depth), scoreFeedback (quality of received feedback), and scoreLegitimacy (Sybil-resistance and legitimacy signals).

Example use cases

Example prompt

“What's the trust score for Base agent base:1378? I want to know if it's safe to hire before delegating a task to it — give me the full breakdown including profile, feedback, and legitimacy scores.”

Technical details

Endpoint

GEThttps://api.thetrustlayer.xyz/score/%7BagentId%7D

When to prefer

Use this endpoint when you need a quick, single-agent trust score summary with component breakdown before initiating agent-to-agent interactions, hiring an agent, or delegating tasks. Prefer this over the full profile or forensics endpoints when you only need the numeric trust signal and don't need full feedback history, time-series data, or Sybil forensics detail.

Side effects

Agent ID not found on specified chain — returns 404 or empty result
Malformed agentId format (missing chain prefix) — returns 400 validation error
Unsupported chain identifier — returns error indicating chain not indexed
Payment failure via x402 micropayment — returns 402 Payment Required
Rate limiting or quota exceeded — returns 429
Agent exists but has insufficient data for scoring — may return null or zero scores
