## 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

```

Example prompt: Can you pull the OHLC price history for ETH over the last 7 days so I can see how the highs and lows trended?

## When to prefer this

Choose this endpoint when you need verifiable, on-chain-sourced OHLC price history for crypto assets without requiring an API key or account setup, and when you're comfortable with pay-per-call micropayment billing in USDC via x402. It is especially useful for DeFi-native workflows where data provenance from real AMM pool state matters, or when integrating into autonomous agent pipelines that need deterministic historical price data.

## Known failure modes

- Invalid or unrecognized token/asset identifier returns an error or empty result
- Missing or malformed serviceId field causes request rejection
- Requested time range has no on-chain data available
- x402 payment failure or insufficient USDC balance blocks the call
- Malformed JSON request body returns a parse error
- Network or node unavailability results in a timeout
