## 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 whatchuneed-token-search-1b6acbb0 -d '<json body>'
```

Example prompt: Search for cryptocurrency tokens matching 'solana' and tell me their market cap rank and symbol.

## When to prefer this

Use this endpoint when you need to quickly look up cryptocurrency tokens by name or symbol and retrieve their market cap rank, especially in a pay-per-call context via x402 protocol. Prefer this over broader market data APIs when you need lightweight token identification without full OHLCV or historical data.

## Known failure modes

- Empty results array if no tokens match the query string
- Missing or null market_cap_rank for tokens not ranked in top markets
- 400 or validation error if 'query' field is absent from the request body
- Payment failure (402) if x402 protocol payment is not correctly attached
- Ambiguous results when query matches many tokens (e.g. searching 'b')
