How this service works
Is this counterparty safe to pay? Screens the address against the OFAC sanctions list, reads its ERC-8004 reputation with coordinated feedback filtered out, and returns an explainable 0-100 trust score with a proceed / hold / block recommendation. Reports insufficient_data rather than guessing when the evidence is not there.
Output
A JSON object containing: trustScore (0-100, higher = safer, null if unevaluable), riskBand (minimal/low/moderate/elevated/severe/unknown), recommendation (proceed/proceed_with_caution/hold/block/insufficient_data), confidence (0-1), flags (array of {code, severity, title, detail}), components (per-rule scoring breakdown), and overrides (hard caps applied after weighting with reasons).
Example use cases
Pre-payment agent safety check
“I'm about to pay an AI agent at address 0xA1B2C3D4E5F6...7890 on Base — can you verify it through TrustAgent and tell me the trust score and recommendation before I approve anything?”
DeFi contract risk screening
“Before my user interacts with this DeFi protocol at 0xDeF1...C0de on Base, run it through TrustAgent as a defi_protocol type and tell me the risk band, any flags, and whether it's safe to proceed.”
Unknown wallet risk assessment
“Someone just sent a payment request from 0x9999...AAAA and I don't recognise it — can you check that address on TrustAgent as an unregistered_address type and give me the full breakdown including flags and confidence?”
Technical details
Endpoint
GEThttps://trust-agent.io/v1/verify/quickWhen to prefer
Use TrustAgent Quick Verify when an agent needs a fast, opinionated safety judgment (proceed/block/hold) for a Base chain address before executing a payment or interaction. It is purpose-built for ERC-8004 agent-to-agent payment safety, DeFi contract screening, and pre-transaction risk gating — prefer it over generic blockchain analytics tools when you need a structured recommendation with per-rule scoring components and hard override caps rather than raw on-chain data.
Side effects
- Address not found or not indexed on Base — returns insufficient_data recommendation with null trustScore
- Chain other than 'base' specified — request refused rather than answered from wrong chain
- Malformed or non-EVM address input — likely 400 validation error
- Insufficient on-chain evidence to evaluate — confidence near 0, recommendation is insufficient_data (not risky)
- Payment failure for x402 micropayment — endpoint returns 402 before evaluation occurs
