## 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-defillama-token-price-lookup-46dc5482
```

Example prompt: What are the current prices for PEPE and Dogecoin? Look them up using their CoinGecko IDs coingecko:pepe and coingecko:dogecoin.

## When to prefer this

Choose this endpoint when you need real-time token prices for CoinGecko-listed coins or EVM on-chain tokens via contract address, especially in a DeFi or crypto-native context. It supports batch lookups (comma-separated) and both CoinGecko slugs and raw contract addresses, making it versatile for portfolio tools, trading bots, or DeFi dashboards.

## Known failure modes

- Invalid or unrecognized coin identifier returns error or missing entry
- Coin not indexed by DeFiLlama returns null or empty price
- Malformed coin identifier format (missing chain prefix) causes lookup failure
- Rate limiting or payment failure ($0.001 USDC per call) returns 402 error
- Network timeout for high-volume comma-separated coin lists

## 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 prices keyed by coin identifier (e.g. coingecko:pepe, coingecko:dogecoin), sourced from DeFiLlama's price aggregation service.
