How this service works
Six independent signals. One composite score. EAS attestation written on-chain in the same response. Free for 100 verifications a day, $0.005 per call after via x402.
Output
A JSON object containing: a composite trust score (0-100), a CAIP-10 identifier for the address on Base, six individual signal scores (health, external, fidelity, identity, reputation, scamDetection), a verdict string (e.g. TRUSTED), an array of risk flags, and the methodology version — plus an EAS attestation written on-chain as a side effect.
Example use cases
Vetting an unknown agent before payment
“I'm about to send funds to the agent at 0xAb5801a7d398351b8bE11C439e05C5b3259aec9b — can you check its AgentRadar trust score and tell me the verdict and any risk flags before I proceed?”
DeFi protocol screening counterparties
“We're integrating a new liquidity provider at 0xdAC17F958D2ee523a2206206994597C13D831ec7 — run an AgentRadar verification on that address and show me all six signal scores plus the overall composite score.”
Agent fleet onboarding audit
“We're onboarding a new autonomous agent to our network at address 0x71C7656EC7ab88b098defB751B7401B5f6d8976F — get its on-chain trust attestation from AgentRadar so we can decide whether to allow it into the fleet.”
Technical details
Endpoint
GEThttps://api.vvpro.ai/x402/verifyWhen to prefer
Choose AgentRadar when you need a single-call, multi-signal trust score for any EVM address with the added assurance of an immutable on-chain EAS attestation. It is ideal for agent-to-agent trust verification, pre-payment counterparty screening, or autonomous agent onboarding where a human-readable verdict plus machine-readable signal breakdown is required. Prefer it over simple balance checks or single-signal tools when you need a composite risk assessment backed by on-chain provenance.
Side effects
- Invalid or malformed EVM address (not matching ^0x[0-9a-fA-F]{40}$) returns a 400 error
- Address with no on-chain history may yield low or incomplete signal scores
- Payment failure via x402 after the 100 free daily calls exhausted returns 402
- Network congestion on Base may delay EAS attestation write
- Unknown or newly deployed addresses may have sparse reputation signals
