## 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 x402-fiasignals-com-dc6e1cc0
```

Example prompt: Before I swap, run a safety batch check on these 3 Base token contracts — 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, 0x4200000000000000000000000000000000000006, 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — and tell me which ones are safe, risky, or blocked, with their scores and any honeypot or rugpull warnings.

## When to prefer this

Use this endpoint when an AI trading agent, swap router, or bot needs to pre-screen one to five Base or EVM token contracts for safety before executing a trade. Ideal when you need aggregated verdicts combining GoPlus and DexScreener evidence in a single paid call rather than querying multiple free data sources separately. Best for agentic A2A commerce flows that require fast, actionable safe/risky/blocked decisions with scoring and warnings at the point of swap.

## Known failure modes

- Payment not received — 402 response returned if USDC microtransaction not completed
- Invalid or malformed token address returns an error verdict for that token
- More than 5 addresses provided causes request rejection
- Unsupported chain identifier returns an error
- Downstream GoPlus or DexScreener data unavailable causes partial error results
- Network timeout on slow contract lookups

## How this service works

Batch Base token safety, honeypot, rug-check and swap-preflight verdicts for up to 5 EVM contracts before a buyer agent signs or routes a swap. Returns PROCEED/CAUTION/REJECT actions, safety scores, evidence, warnings, aggregate counts, and a non-breaking 0.50 USDC bundled-risk-pack payable tier. Free single-token preview: /token-safety/free. Search keywords: rug check, honeypot check, token risk, swap preflight, rug pull, scam token, and is this token safe.

## Output

Returns a results array with one entry per token, each containing a verdict (safe/risky/blocked/error), a 0-100 safety score, confidence level, list of warnings and reasons, recommended action, raw_checks from GoPlus and DexScreener, and an aggregate summary object with counts of safe/risky/blocked/error tokens across the batch.
