## 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 tokenguard-screener-d8729aef -d '<json body>'
```

Example prompt: Screen the top DeFi tokens on Ethereum for me — I want to see which ones pass safety checks, have decent liquidity, and look healthy on-chain so I can decide which are worth investing in.

## When to prefer this

Choose this endpoint when you need to screen multiple crypto tokens simultaneously for safety and DeFi analytics, particularly for ERC-20 tokens on Base or Ethereum. Prefer it over single-token lookup endpoints when you need comparative risk ranking across a token set, or when you need a combined view of safety, market, and on-chain data in one call. Best suited for pre-investment due diligence, portfolio hygiene checks, and automated DeFi agent workflows that require micropayment-native access via x402.

## Known failure modes

- Empty response body if no tokens match the screening criteria
- Invalid or unrecognized token addresses return error or empty results
- Network/chain not supported returns an error
- Payment failure via x402 micropayment protocol blocks the request
- Rate limiting or quota exhaustion on the Hugging Face Space host
- Stale or delayed on-chain data if the indexer is behind

## How this service works

screener data for AI agents.

## Output

Returns a JSON object containing screened token results including safety scores, market metrics (price, volume, liquidity), on-chain analytics (holder distribution, contract risk flags), and DeFi-specific data points that help evaluate token quality and risk.
