## 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

```

Example prompt: What are the current prices of Immutable X and Blur — can you look them up using their CoinGecko IDs coingecko:immutable-x and coingecko:blur?

## When to prefer this

Choose this endpoint when you need real-time USD prices for one or more crypto tokens and can identify them by CoinGecko slug or EVM contract address. It supports batch lookups via comma-separated lists and is backed by DefiLlama's broad token coverage. Prefer over exchange-specific APIs when you need cross-chain coverage or DeFi-native tokens not listed on centralized exchanges.

## Known failure modes

- Invalid or unrecognized coin identifier returns empty or error data
- Rate limiting or payment failure returns 402 Payment Required
- Comma-separated list malformed returns 400 Bad Request
- Token not indexed by DefiLlama returns null or missing price entry
- Network or upstream DefiLlama outage causes 502/503 response

## 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 containing current USD price data for each requested coin identifier, keyed by the coin slug or contract address provided in the request path.
