## 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-api-3299f7db
```

Example prompt: What was the price of ETH over the past 30 days? Fetch me the historical price data — I don't have an API key, so use a pay-per-call source.

## When to prefer this

Choose this endpoint when you need historical cryptocurrency price data without wanting to manage API keys or subscriptions — ideal for agents operating autonomously with a USDC wallet on Base. Prefer this over CoinGecko or CryptoCompare direct APIs when you want keyless, pay-per-call access with normalized responses and multi-source fallback.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Unknown or unsupported token symbol/address — returns 404 or empty result
- Date range out of bounds or unavailable historical depth — returns partial or empty data
- Upstream data provider unavailable — may return 503 or fallback partial data
- Malformed query parameters — returns 400 Bad Request

## How this service works

Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.

## Output

A normalized array of historical price records for the requested token, including timestamps and price values (and potentially OHLCV fields), sourced from aggregated public market data providers with edge-cached delivery.
