## 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`):

```

Example prompt: What are the current USD prices for Bitcoin Cash and Litecoin? Use the DeFiLlama price endpoint with coingecko:bitcoin-cash and coingecko:litecoin.

## When to prefer this

Choose this endpoint when you need real-time USD prices for one or more tokens identified by CoinGecko slug or ERC-20 contract address, especially when you want DeFiLlama's aggregated price feed. Particularly useful for DeFi-native workflows where contract-address-based lookup is needed alongside standard CoinGecko IDs, and when pay-per-call (no API key) access via x402/USDC is preferred.

## Known failure modes

- Invalid or unrecognized coin identifier returns an error or empty price entry
- Malformed contract address causes a 400 bad request
- Too many coins in a single comma-separated list may hit size limits
- Token not indexed by DeFiLlama returns null or missing price
- Payment of 0.001 USDC not settled causes 402 Payment Required

## 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 for each requested token, keyed by their coin identifier (e.g. coingecko:bitcoin-cash). Each entry includes the token's price in USD and relevant metadata such as timestamp.
