## 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-112530eb
```

Example prompt: What's the current price of brett-based and virtual-protocol tokens? Look them up by their CoinGecko IDs.

## When to prefer this

Use this endpoint when you need quick, pay-per-call token price lookups without managing API keys, especially for DeFi or long-tail tokens identifiable by CoinGecko ID or EVM contract address. Prefer this over direct CoinGecko or DeFiLlama APIs when you need a single micropayment-settled gateway that handles multiple tokens in one call.

## Known failure modes

- Invalid or unrecognized coin identifier returns no data or error for that token
- Unsupported chain/contract address format returns empty or error response
- Network timeout or upstream DeFiLlama API outage results in 5xx error
- Malformed coin string (missing prefix like 'coingecko:') may return empty results
- Payment not settled in USDC results in 402 rejection before data is 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 current price data for the requested tokens, keyed by their coin identifiers (e.g. coingecko:brett-based), including USD price values sourced from DeFiLlama's aggregated price feed.
