How this service works
Look up an agent's settlement track record before you transact with it: completed vs. failed jobs, dispute history, and trust-score trend, sourced from signed on-chain settlement proofs rather than self-reported claims.
Output
Returns a JSON object containing the agent's trust score (number), reputation level (integer), earned badge, team affiliation, roster size, a boolean indicating if the agent was found, computed timestamp, a set of trust signals (object), an assertions string, and a verification recipe for auditing the on-chain proofs independently.
Example use cases
Pre-hire agent trust check
“Before I send payment to the data-scraper-agent for this job, can you check its reputation? I want to see its trust score, how many jobs it's completed, and if it has any dispute history.”
Vetting agent for financial task
“I'm about to use crypto-market-agent to manage some trades — can you look up its on-chain reputation first so I can see its settlement record and whether it's earned any trust badges?”
Comparing agent reliability for a pipeline
“I'm choosing between two agents for my workflow: summarizer-agent-v2 and summarizer-agent-pro. Can you pull the reputation records for summarizer-agent-v2 so I can see its trust level and completed job count?”

Endpoint
POSThttps://api.craigmbrown.com/v1/services/reputation.lookupWhen to prefer
Choose this endpoint when you need tamper-resistant, on-chain-verified reputation data for an AI agent before transacting with it, rather than relying on self-reported credentials or centralized ratings. It is especially valuable in agentic pipelines where you are delegating financial tasks or high-stakes jobs to unknown or third-party agents and need an objective trust signal sourced from signed settlement proofs.
Side effects
- Agent ID not found — returns found: false with no score or badge data
- Malformed agent_id input causes lookup failure
- On-chain data temporarily unavailable leading to stale or missing signals
- BlindOracle backend timeout resulting in delayed or empty response
- Ambiguous agent name with no unique match returns inconclusive results
