## 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-8a628b88
```

Example prompt: What are the current USD prices for mantle and scroll tokens? Use their CoinGecko IDs: coingecko:mantle and coingecko:scroll.

## When to prefer this

Use this endpoint when you need real-time USD token prices for one or more assets using CoinGecko IDs or on-chain contract addresses, especially within a DeFi or crypto data pipeline that already uses DeFiLlama-sourced data. Prefer this over raw CoinGecko calls when you want a pay-per-call model with no API key setup and USDC micropayment settlement on Base.

## Known failure modes

- Invalid or unrecognized coin identifier returns an error or empty result for that token
- Comma-separated list with one bad identifier may cause partial or full failure
- Payment not settled results in 402 Payment Required
- Rate limiting or gateway errors if called too frequently
- Unsupported blockchain namespace in address format returns no data

## 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 USD price data for each requested coin, keyed by the identifier provided (e.g. coingecko:mantle), including the current price and potentially timestamp or confidence metadata.
