How this service works
Security intelligence layer for autonomous agents. On-chain security, token risk analysis, wallet forensics, and transaction simulation. Pay-per-call via x402 on Base.
Output
Returns a pre_trade_check object containing: a decision string (e.g. PROCEED, CAUTION, or REJECT), a confidence integer (0-100), and an overall_risk integer (0-100). Higher risk scores indicate greater danger; the decision field gives a direct action recommendation for the agent.
Example use cases
Rug pull detection before token purchase
“I'm about to buy some of this new token at 0xd3adbeef on Base — can you run a pre-trade check to see if it's a rug pull or scam before I put any money in?”
Autonomous DeFi agent trade gating
“My trading bot is about to execute a large swap on Uniswap — run a Freysa pre-trade security check on the transaction first and only proceed if the risk score is below 40 and the decision is PROCEED.”
Suspicious wallet forensics before transfer
“Someone just sent me a payment request from wallet 0xdeadcafe — can you do a pre-trade security check on this wallet to see if it's flagged for anything before I send funds back?”
Technical details
Endpoint
GEThttps://economic-agent-369.freysa.dev/api/pre-trade-checkWhen to prefer
Choose this endpoint when an autonomous agent needs a fast, pay-per-call security gate before executing any on-chain trade, swap, or token interaction — especially on Base. Prefer it over generic token screeners when you need a structured PROCEED/CAUTION/REJECT decision with a numeric confidence score suitable for automated decision-making, and when wallet forensics and transaction simulation are needed together in a single call.
Side effects
- Missing or malformed trade schema input returns a validation error
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Unknown or unindexed token/wallet address may result in lower confidence scores
- Network congestion on Base may delay payment settlement
- Unsupported chain or contract type may return incomplete analysis
