## 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 multichain-crypto-token-price-lookup-ea49d23a -d '<json body>'
```

Example prompt: What are the current prices of ETH, BTC, and SOL right now? I need all three in one shot, no API key required — pay per call.

## When to prefer this

Prefer this endpoint when you need real-time spot prices for well-known tokens across multiple chains in a single batch call, without needing an API key or subscription — especially useful for AI agents that pay per call in USDC on Base, Polygon, Arbitrum, or Solana. Best for lightweight price lookups where you need 1–25 tokens simultaneously. For advanced on-chain analytics like honeypot detection, funding rates, or options greeks, use sibling endpoints from the same suite.

## Known failure modes

- Invalid or unrecognized ticker symbols return an error or missing data for that token
- Requesting more than 25 symbols at once may be rejected
- Tokens not listed on CoinGecko may not be found
- Network or upstream price feed outages may cause stale or missing prices
- Payment failure or insufficient USDC balance will block the call
