## 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-82b22041
```

Example prompt: What are the current prices of XRP and Stellar? Look them up by their CoinGecko IDs: coingecko:xrp and coingecko:stellar.

## When to prefer this

Use this endpoint when you need real-time or near-real-time USD prices for one or more tokens identified by CoinGecko slug or EVM contract address, especially in a pay-per-call context without needing a persistent API key. Ideal for DeFi workflows, portfolio valuation, or any agent needing broad multi-token price coverage via DefiLlama's aggregated feed.

## Known failure modes

- Invalid or unrecognized coin identifier returns an error or missing entry
- Malformed path parameter (bad format) causes a 400 or 404 response
- DefiLlama data unavailable for obscure tokens results in null or missing price
- Payment failure (insufficient USDC balance) blocks the call at the x402 layer

## 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 with current USD prices for each requested coin identifier, keyed by the coin identifier string (e.g. coingecko:xrp → price in USD).
