How this service works
Reviewer quality lookup. Returns quality score and review history for a wallet address that has left ERC-8004 feedback.
Output
Returns a JSON object containing: whether the reviewer was found, the wallet address, a qualityTier string (e.g. 'unknown', 'bronze', 'silver', 'gold'), a numeric reviewerScore (null if no history), totalReviews count, uniqueAgentsReviewed count, and an array of recentReviews. If the address has no review history, found is false and most fields are zero or null.
Example use cases
Example prompt
“Can you check TrustLayer to see what quality score and review history the wallet 0x1234567890123456789012345678901234567890 has as an ERC-8004 reviewer — I want to know their quality tier and how many agents they've reviewed?”
Technical details
Endpoint
GEThttps://api.thetrustlayer.xyz/reviewer/:addressWhen to prefer
Use this endpoint when you need to assess the credibility or reputation of a specific wallet address as a reviewer in the ERC-8004 ecosystem, particularly before weighting their feedback in agent trust calculations. Prefer this over the full feedback forensics endpoint when you only need a quick quality tier and review count rather than deep Sybil detection or cross-chain identity resolution.
Side effects
- Address not found — returns found:false with zeroed metrics rather than an error
- Invalid address format — may return 400 or empty result if the address is not a valid 0x Ethereum address
- Network/RPC latency — on-chain indexing lag may mean very recent reviews are not yet reflected
- Rate limiting — low-cost endpoint but high-volume callers may be throttled
- Address with no ERC-8004 activity returns qualityTier:'unknown' and reviewerScore:null
