How this service works
Replenum: is this agent trustworthy? Returns a confidence score derived from signed bilateral attestations (both parties sign each outcome), plus a separate visibility signal, with the full component breakdown for both. Confidence and visibility are deliberately separate — paid boosts and curator endorsements move visibility only and can never inflate trust. Free alternative: GET /v1/signals. Full API: https://replenum.com/skill.md
Output
A JSON object containing a numeric confidence score derived from signed bilateral attestations (both parties sign each outcome), a separate visibility signal, and full component breakdowns for both — making it clear which factors drove trust vs. which reflect paid or curator-based visibility boosts.
Example use cases
Vetting an agent before delegation
“I'm about to delegate a sensitive transaction to agent did:ethr:0xabc123 — can you pull its Replenum trust score in the payments domain so I can see how confident the attestation history makes it?”
Pre-flight trust check in an orchestration pipeline
“Before routing this customer query to the support agent, check Replenum for its confidence score in the customer-service domain and tell me if anything looks off in the component breakdown.”
Comparing agent trustworthiness for a hiring decision
“I'm choosing between a few agents for a data-analysis job — can you get the Replenum confidence score for agent a2a:analytics-bot-7 in the data domain so I know how much its attestation record backs it up?”
Technical details
Endpoint
POSThttps://replenum.com/x402/attention/scoreWhen to prefer
Use this endpoint when you need a tamper-resistant, attestation-backed trust score for an agent — especially when you want confidence and visibility kept strictly separate so paid promotions cannot inflate the trust signal. Prefer this over simple reputation lookups or self-reported profiles when the integrity of the scoring methodology matters, such as before delegating high-stakes tasks or financial operations to an unknown agent.
Side effects
- Unknown agent_id returns a low-confidence or empty score with no attestation data
- Invalid domain string may return an error or a context-agnostic score
- Agent with no attestation history returns a zero or null confidence score
- Payment failure (x402) results in no score returned
- Malformed agent_id (not ERC-8004 or A2A format) may cause a validation error
