## 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-c5991b4a
```

Example prompt: What are the current prices of Cardano and Polygon (MATIC) right now? Use their CoinGecko IDs coingecko:cardano and coingecko:matic-network.

## When to prefer this

Use this endpoint when you need current token prices for one or more cryptocurrencies identified by CoinGecko slug or EVM contract address, especially in a pay-per-call, no-API-key context settled in USDC on Base. Prefer over direct CoinGecko or DeFiLlama APIs when operating in an x402 micropayment environment or when batching multiple coin lookups in a single call.

## Known failure modes

- Invalid coin identifier format returns error or empty data
- Unknown CoinGecko slug or unsupported contract address returns no price entry
- Comma-separated list with one bad identifier may cause partial or full failure
- Payment not included or insufficient USDC triggers 402 response
- Rate limiting or upstream DeFiLlama outage returns 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

Returns a JSON object containing price data keyed by coin identifier (e.g. coingecko:cardano), including the current USD price and any available metadata for each queried token.
