## 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 blockrun-ai-token-price-lookup-defillama-eb3b32be
```

Example prompt: What's the current price of Dogecoin and Ethereum? Use their CoinGecko IDs — coingecko:dogecoin and coingecko:ethereum.

## When to prefer this

Choose this endpoint when you need real-time token prices for one or more cryptocurrencies using either CoinGecko slugs or on-chain contract addresses. It is especially useful for DeFi workflows where ERC-20 or multi-chain token prices are needed by contract address, which many simpler price APIs do not support. Prefer this over exchange-specific price feeds when you need broad multi-chain coverage backed by DefiLlama aggregation.

## Known failure modes

- Invalid or unrecognized coin identifier returns an error or empty result
- Network/upstream DefiLlama API unavailability causes timeout or 5xx error
- Malformed coin identifier format (missing chain prefix) may return no data
- Very new or illiquid tokens may not have price data available

## How this service works

Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.

## Output

Returns a price data object keyed by coin identifier (e.g. 'coingecko:dogecoin'), containing the current USD price and likely a timestamp or confidence metadata as provided by DefiLlama's price feed.
