## 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 stablecrypto-dev-77293345 -d '<json body>'
```

Example prompt: Can you pull the historical price data for ETH and WBTC from Alchemy for the past 90 days so I can see how they trended?

## When to prefer this

Use this endpoint when you need historical price data specifically for tokens supported by Alchemy, such as ETH and major ERC-20s, and want time-series pricing rather than current spot prices. Prefer this over DeFiLlama endpoints if you want Alchemy's curated asset coverage.

## Known failure modes

- Token not supported by Alchemy returns an error or empty result
- Invalid date range causes a 400 bad request
- Unsupported network or asset symbol returns no data
- Malformed request body causes parsing error
- Service outage or upstream Alchemy API failure returns 5xx

## How this service works
