## 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 verdictswarm-pre-trade-risk-gate-cc57c4ce -d '<json body>'
```

Example prompt: Before you swap into that token, run a VerdictSwarm risk check on Base contract address 0xAbCd...1234 and tell me the verdict and confidence score — use the fast level and include honeypot and LP lock signals.

## When to prefer this

Use VerdictSwarm when your agent needs a fast, structured, multi-signal token risk verdict with a clear pass/caution/fail label before executing any on-chain trade on Solana or Base. Prefer this over general on-chain data APIs when you need an opinionated, pre-classified verdict (not raw data) that combines honeypot detection, LP lock status, and mint authority checks into a single confidence-weighted decision, charged per-call at $0.01 USDC with x402.

## Known failure modes

- Invalid or unsupported chain value — only 'solana' and 'base' are accepted
- Token address not found on specified chain — returns error or low-confidence verdict
- Payment failure via x402 — call rejected if USDC balance is insufficient
- Stale data exceeding max_staleness_seconds — service may return error or refresh live
- High network latency causing timeout for live (non-cached) lookups
- Malformed contract address format triggering validation error

## How this service works

Call VerdictSwarm before your agent moves money. Get avoid, caution, or clear token-risk verdicts through API, ACP, MCP, or the web scanner.

## Output

A JSON object containing the verdict (avoid, caution, or clear), a numeric risk score (0-100), a confidence value (0-1), boolean signals for honeypot detection, LP lock status, and mint authority revocation, plus billing confirmation of $0.01 USDC charged via x402 and a flag indicating whether the result was served from cache.
