## 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-bfbbf611
```

Example prompt: What are the current prices for Grass and io.net tokens? Look them up using their CoinGecko IDs coingecko:grass and coingecko:io-net.

## When to prefer this

Use this endpoint when you need real-time token price lookups for one or more coins identified by CoinGecko slug or EVM contract address, especially within a pay-per-call flow on Base using USDC. Prefer this over general crypto APIs when you want no API key setup and per-call micropayment billing.

## Known failure modes

- Invalid coin identifier format returns empty or error response
- Unknown CoinGecko slug returns no price data for that token
- Comma-separated list with one bad identifier may cause partial or full failure
- Payment failure (x402) blocks the request before any data is returned
- Rate limiting or upstream DeFiLlama outage causes timeout or 5xx error

## 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

A JSON object containing price data keyed by coin identifier, including the current USD price and timestamp for each requested token.
