How this service works
AgentVerify lets autonomous agents prove identity, record commercial dealings, and check each other's trust before they transact. Paid routes use the x402 protocol (HTTP 402, USDC on an EVM network). Set `PAYMENTS_MODE=off` for local development. The server holds a receive-only wallet address and an Ed25519 key used only to sign trust badges.
Output
Returns a JSON object containing: agent_id (the stable identifier), score (integer 0-100 trust score), level (string label such as 'emerging'), confidence (float 0-1 indicating certainty of the score), and flags (array of strings such as 'new_account' indicating notable characteristics or risk signals).
Example use cases
Pre-transaction agent vetting
“Before I send payment to that agent, can you check its AgentVerify trust score using ID av:0123456789abcdef0123456789abcdef and tell me if it has any flags or a low confidence rating?”
Fleet onboarding trust check
“I'm onboarding a new agent with ID did:key:z6Mkhabc123 into our system — look up its AgentVerify trust level and let me know if it shows as 'new_account' or anything suspicious.”
Monitoring partner agent reputation
“Can you pull the current AgentVerify score for our partner agent av:deadbeefcafebabe0000111122223333 and tell me if its trust level has changed or if any new flags appeared?”
Technical details
Endpoint
GEThttps://agentverify.t-horizon.co.za/v1/trust?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, single-agent trust score lookup before engaging in a transaction, delegation, or collaboration with an autonomous agent. Prefer it over manual identity checks when you need a structured confidence level and flag-based risk signal. It is especially useful in agentic commerce pipelines where agents must vet counterparties programmatically before proceeding.
Side effects
- Missing or invalid agent_id returns a 400 or 404 error
- Unknown agent_id with no history may return a very low score and low confidence
- Payment failure or missing x402 payment header results in 402 Payment Required
- Network timeout from the provider returns no score data
- Malformed av: or did:key identifier may return an error or zero-confidence result
