## 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-01ad6aac
```

Example prompt: What's the current price of Bitcoin and WETH? Use coingecko:bitcoin and ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2.

## When to prefer this

Use this endpoint when you need real-time token prices for one or more assets identified by CoinGecko IDs or Ethereum contract addresses, especially within a DeFi or on-chain analytics workflow, and you want DeFiLlama's aggregated pricing without a separate API key.

## Known failure modes

- Invalid coin identifier format returns empty or error response
- Unknown token ID returns no price data
- Network or gateway timeout
- Malformed comma-separated list results in partial or failed lookup
- Payment of 0.001 USDC not settled causes 402 rejection

## 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 map of coin identifiers to their current USD prices as sourced from DeFiLlama, covering both CoinGecko-listed tokens and on-chain ERC-20 contracts.
