How this service works
Should you approve this contract? Everything in quick, plus static analysis of the bytecode: privileged functions (mint, pause, blacklist, arbitrary withdrawal), proxy and upgradeability detection, dangerous opcodes, DeFi protocol classification and source-verification status.
Output
Returns a JSON object with: trustScore (0-100, higher is safer, null if no rules could evaluate), riskBand (minimal | low | moderate | elevated | severe | unknown), recommendation (proceed | proceed_with_caution | hold | block | insufficient_data), confidence (0-1), per-rule scoring components, hard-cap overrides with reasons, contract bytecode analysis (opcodes, proxy kind, privileged functions, protocol class, safetyScore), and address-specific flags.
Example use cases
Pre-payment contract safety gate
“My agent is about to send USDC to 0xAbCd...1234 on Base — can you run a deep trust check on that address and tell me the risk band and whether to proceed or block the payment?”
DeFi protocol due diligence
“I'm thinking of depositing into a DeFi protocol at 0x9876...FEDC on Base. Can you analyze it as a defi_protocol and give me a trust score plus any flags I should know about?”
Agent-to-agent payment vetting
“Before I whitelist this agent wallet 0xDEAD...BEEF on Base for recurring payments, can you do a deep verify and tell me the confidence level and recommendation?”
Technical details
Endpoint
GEThttps://trust-agent.io/v1/verify/deepWhen to prefer
Choose this endpoint when an AI agent needs to make a go/no-go payment decision about a Base-chain contract, DeFi protocol, or agent wallet before executing a transaction. It is purpose-built for ERC-8004 payment safety gating and returns a structured recommendation (proceed/block) rather than raw on-chain data, making it ideal for autonomous agent workflows where a binary or banded safety signal is needed without manual review.
Side effects
- Address not on Base chain — any chain other than 'base' is refused rather than answered from a different chain
- Address not found or undeployed — returns recommendation: insufficient_data with null trustScore
- Insufficient on-chain evidence — confidence near zero, recommendation: insufficient_data (treat as unknown, not risky)
- Invalid address format — likely 400 error
- Rate or payment failure — 402 Payment Required if x402 payment not completed
