## 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 santyvv-data-historical-token-price-by-contract-ec66c39e
```

Example prompt: What was the price of the WETH token (contract 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) on Ethereum at Unix timestamp 1700000000?

## When to prefer this

Use this endpoint when you need the price of a specific ERC-20 token at an exact past moment in time identified by Unix timestamp and contract address — ideal for transaction audits, historical portfolio valuations, P&L calculations, and tax reporting where point-in-time accuracy is critical. Prefer this over live-price endpoints when the moment of interest is in the past.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unix timestamp out of supported historical range returns no data
- Unsupported chain or network returns an error
- Token contract with no price feed history at that timestamp returns null or error
- Missing required query parameters returns a 400-level validation error

## How this service works
