## 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-3a7233a1
```

Example prompt: What are the current prices of Solana and Avalanche? Look them up using their CoinGecko IDs coingecko:solana and coingecko:avalanche-2.

## When to prefer this

Use this endpoint when you need current crypto token prices for one or more assets identified by CoinGecko slugs or on-chain ERC-20/EVM contract addresses, especially when integrating DefiLlama's broad DeFi coverage. Prefer this over exchange-specific APIs when you need cross-chain token prices or prices for long-tail DeFi tokens not listed on major CEXs.

## Known failure modes

- Invalid or unrecognized coin identifier returns no price data or error
- Unsupported chain prefix causes lookup failure
- Rate limiting or payment failure returns 402 or 429
- Malformed comma-separated list may result in partial or empty results
- Token not tracked by DefiLlama returns missing price entry

## 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 with current USD prices keyed by the coin identifiers provided (e.g. CoinGecko slugs or contract addresses), sourced from DefiLlama's price aggregation feed.
