## 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-market-data-5839d17a -d '<json body>'
```

Example prompt: What are the current market stats for Bitcoin — I want to see the all-time high, how far it is from ATH, market cap, 24h volume, and circulating supply.

## When to prefer this

Choose this endpoint when you need structured cryptocurrency market data — especially ATH metrics and supply figures — in a single pay-per-call request without a recurring API subscription. Useful for agents that need on-demand crypto stats without maintaining a CoinGecko or CoinMarketCap API key.

## Known failure modes

- Unknown or unsupported coin symbol returns an error or empty response
- Misspelled coin ticker may return no data
- Payment of 0.15 USDC required per call via x402 protocol; missing payment results in 402 error
- Stale data possible if underlying data source is not updated in real-time
