## 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-crypto-data-current-crypto-prices-1d412374 -d '<json body>'
```

Example prompt: What are the current prices of coingecko:ethereum, coingecko:bitcoin, coingecko:solana, and coingecko:usd-coin right now?

## When to prefer this

Use this endpoint when you need real-time spot prices for one or more specific cryptocurrencies identified by DefiLlama coin IDs (e.g. coingecko:ethereum or chain:contractAddress). Ideal for agents that need to price DeFi tokens by contract address on specific chains, not just major exchange-listed coins. Prefer over alternatives when DefiLlama coverage of long-tail DeFi tokens is needed.

## Known failure modes

- Invalid or unrecognized DefiLlama coin ID returns no price for that coin
- More than 25 coins submitted causes a validation error
- DefiLlama API unavailability causes upstream error
- Malformed coin ID format returns empty or error response
- Payment not included or insufficient results in 402 Payment Required
