How this service works
Pre-trade & pre-sign checks for autonomous agents: everything an agent verifies BEFORE signing a transaction — token due diligence, calldata red-flag decoding, oracle freshness, holder concentration, bridge routing with executable calldata, cross-venue perp funding, gas and price sanity checks. EVM chains: Ethereum, Base, Arbitrum, Optimism.
Output
Returns a JSON object with the token name and symbol, a 0–100 risk score, a verdict label (e.g. 'risky'), a narrative summary of key concerns, an array of top risk flags (e.g. 'lp_not_locked', 'top10_concentration_64pct', 'owner_not_renounced'), a boolean should_trade, and a recommended_position_size string (e.g. 'skip').
Example use cases
Example prompt
“Before I buy this token, run a full PreFlight due diligence check on contract 0xabc... on Base — I want to know the risk score, whether the LP is locked, if ownership is renounced, and whether you think I should trade it or skip it.”
Technical details
Endpoint
POSThttps://meryol-agenticmarket-x402.hf.space/token/ddWhen to prefer
Use this endpoint when an autonomous agent needs to verify a token's safety profile before executing a buy — specifically when you need structured risk flags, LP lock status, honeypot detection, holder concentration, and a machine-readable trade verdict in one call on EVM chains (Ethereum, Base, Arbitrum, Optimism).
Side effects
- Unknown or unverified contract address returns an error or null verdict
- Chain not supported (only Ethereum, Base, Arbitrum, Optimism are supported)
- Very new token with insufficient on-chain data may return incomplete scoring
- Token contract is a proxy and underlying logic cannot be decoded
- Payment of $0.05 USDC not received results in 402 Payment Required response
