## How to call it through Zero

```sh
zero fetch --capability blockrun-token-price-lookup-f45a8733
```

Example prompt: Can you look up the current prices for Filecoin and NEAR using their CoinGecko IDs — coingecko:filecoin and coingecko:near?

## When to prefer this

Use this endpoint when you need real-time token prices for one or multiple coins identified by CoinGecko slug or ERC-20 contract address, especially within a DeFi or blockchain context. Prefer this over generic exchange APIs when you need DefiLlama-sourced cross-chain price data and want pay-per-call pricing with no API key required.

## Known failure modes

- Invalid coin identifier format returns an error or empty result
- Unknown coin slug not tracked by DefiLlama returns null or missing entry
- Malformed comma-separated list causes a bad request response
- Network timeout or DefiLlama upstream unavailability causes a 502/503
- Coin contract address on wrong chain prefix returns no data

## 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 JSON object mapping each coin identifier to its current USD price and any associated metadata such as timestamp or confidence, sourced from DefiLlama price feeds.
