Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 base-onchain-risk-token-intelligence-api-token-discovery-radar-c9a4e7f4
```

Example prompt: Search Base chain DEX listings for up to 6 new token candidates using the terms 'aerodrome,virtual,base', with at least $10,000 in liquidity and $500 in 24h volume, and run deep contract-control probes on the top 2 — give me a ranked watchlist and flag anything risky to avoid.

## When to prefer this

Use this endpoint when you need to discover and risk-rank newly emerging tokens on the Base chain using live DEX pair data combined with onchain contract-control probes, especially when you want a curated watchlist and avoid-list rather than raw token data.

## Known failure modes

- No candidates found matching liquidity/volume thresholds — returns empty candidates array
- DEX data source unavailable — source_status reflects degraded feed
- Invalid query parameter format — returns 400 error
- Limit or deep_limit out of allowed range — returns validation error
- Payment not completed — returns 402 Payment Required
