## 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 x402-gateway-production-up-railway-app-c24ec8be -d '<json body>'
```

Example prompt: Can you get me the current DEX-derived prices and OHLC data for these tokens: ETH, BTC, UNI, AAVE, and LINK?

## When to prefer this

Use this endpoint when you need real-time, DEX-sourced token prices (not centralized exchange prices) with OHLC candlestick data, especially for DeFi tokens or long-tail assets that may not be listed on CEXs. Ideal for batch lookups of up to 200 tokens in a single call. Prefer this over CEX price feeds when DEX liquidity data or on-chain pricing is specifically required.

## Known failure modes

- Request exceeds 200 tokens — returns error indicating batch size limit
- Invalid or unrecognized token address/symbol — returns null or error for that token
- DEX liquidity data unavailable for obscure tokens — may return empty or stale data
- Payment not processed (x402 payment required) — returns 402 Payment Required
- Network timeout from DEX data aggregation — returns 503 or timeout error
