## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability freysa-intelligence-pre-trade-check-440e7f04
```

Example prompt: Before I swap 500 USDC for this token at address 0xabc123 on Base, run a pre-trade security check and tell me whether it's safe to proceed — give me the risk decision, confidence level, and overall risk score.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
