## 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 lastlook-data-crypto-historical-daily-closing-prices-8842b201
```

Example prompt: Can you pull the daily closing prices for Bitcoin over the last 365 days so I can see the full year's price history?

## When to prefer this

Use this endpoint when you need historical daily closing price series for a specific top-20 cryptocurrency over a fixed window of 30, 90, or 365 days. Prefer it over spot-price endpoints when trend analysis, backtesting, or charting is needed. Best when CoinGecko-sourced data is acceptable and only end-of-day granularity is required.

## Known failure modes

- Unsupported coin symbol returns an error — only BTC, ETH, SOL, BNB, XRP, USDT, USDC, ADA, AVAX, DOGE, DOT, MATIC, LINK, LTC, ATOM, UNI, SUI, APT, NEAR, PEPE are valid
- Invalid days value returns an error — only '30', '90', or '365' are accepted
- Missing required query parameters (coin or days) results in a bad request error
- CoinGecko upstream outage may cause data unavailability
- Payment failure (x402) if insufficient USDC balance provided
