## 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-defillama-token-price-lookup-92852be1
```

Example prompt: What are the current prices of Ethereum and Solana? Look them up using their CoinGecko IDs — coingecko:ethereum and coingecko:solana.

## When to prefer this

Use this endpoint when you need current token prices for one or more crypto assets identified by CoinGecko slug or on-chain contract address, without requiring an API key — especially in pay-per-call agent workflows settled in USDC on Base. Ideal when querying DeFi tokens not always available on centralized exchange APIs.

## Known failure modes

- Invalid or unrecognized coin identifier returns an error or missing entry in the response
- Malformed coin format (missing chain prefix) may return no price data
- Network or upstream DeFiLlama outage results in a 5xx error
- Payment failure (insufficient USDC balance) results in a 402 response and no data returned

## 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 (e.g. 'coingecko:ethereum') to its current USD price, sourced from the DeFiLlama price feed. Supports multiple coins returned in a single response.
