## 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-defi-token-price-lookup-303bd6c1
```

Example prompt: What are the current prices for the Movement and Sonic tokens right now? Use their CoinGecko IDs — coingecko:movement and coingecko:sonic-3.

## When to prefer this

Use this endpoint when you need real-time or near-real-time token prices for CoinGecko-listed coins or on-chain ERC-20 tokens, especially in a pay-per-call context without requiring API keys. Prefer this over raw DefiLlama API calls when you need a simple, paid-access price lookup integrated into an x402 payment flow on Base.

## Known failure modes

- Unknown or misspelled coin identifier returns empty or null price entry
- Invalid format for coin identifier returns an error
- Network or upstream DefiLlama feed unavailability causes timeout or 5xx
- Payment not included or insufficient USDC results in 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

A JSON object mapping each requested coin identifier to its current price (and possibly additional metadata like timestamp or confidence), sourced from DefiLlama's price aggregation feeds.
