## How to call it through Zero

```sh
zero fetch --capability blockrun-ai-token-price-lookup-5cb4a80a
```

Example prompt: What are the current prices of Aerodrome Finance, Brett, and Nomad tokens right now? Use CoinGecko identifiers like coingecko:aerodrome-finance, coingecko:brett, and coingecko:nomad.

## When to prefer this

Choose this endpoint when you need real-time token prices using CoinGecko slugs or on-chain contract addresses, especially for DeFi tokens not easily found on centralized exchanges. It's ideal for batch multi-token price lookups in a single call and integrates DeFiLlama's broad cross-chain coverage at a very low per-call cost ($0.002 USDC).

## Known failure modes

- Unknown or misspelled coin identifier returns no data or an error for that token
- Invalid format for contract address causes lookup failure
- Comma-separated list with unsupported coin platforms may return partial results
- Network or upstream DeFiLlama API downtime results in a 5xx error
- Rate limiting or payment failure (x402) blocks the request

## 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

A JSON object mapping each requested coin identifier to its current USD price, returned for all coins supplied in the path parameter as a comma-separated list.
