## 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 amanchain-price-history-ohlc-7f827cb9 -d '<json body>'
```

Example prompt: Pull the OHLC price history for the AMAN token on AmanChain so I can see how its price has moved over the past 30 days.

## When to prefer this

Choose this endpoint when you need deterministic, node-verified OHLC price history sourced directly from AmanChain on-chain state without requiring an API key or account — ideal for agents that need trustless, auditable price candle data for DeFi tokens traded on AmanChain DEXes, paid per call via x402 USDC microtransaction.

## Known failure modes

- Invalid or unknown token identifier returns an error or empty dataset
- Insufficient USDC balance for x402 payment causes call to fail with payment error
- Malformed JSON body or missing serviceId field returns a validation error
- Node unavailability or consensus lag may delay or fail the response
- Requesting time ranges with no available data returns empty or partial results
