## 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-fe66c764
```

Example prompt: What's the current price of ETH, SOL, and USDC right now? Use DeFiLlama price data — I need the live valuations for those three tokens.

## When to prefer this

Choose this endpoint when you need real-time token price data from DeFiLlama without managing API keys, and you are operating in a crypto-native environment already using x402 micropayments on Base or Solana. Ideal for AI agents that need on-demand price lookups billed per-call in USDC.

## Known failure modes

- Invalid or unrecognized coin identifiers return empty or null data
- Payment failure (402) if USDC balance is insufficient on Base or Solana
- Rate limiting or gateway timeout if the DeFiLlama upstream is slow
- Malformed coin path parameter causes a 400 or routing error
- Unsupported chain prefix in coin identifier yields no result

## 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 current price data for the requested coin identifiers, sourced from DeFiLlama. The response includes price values keyed by coin identifier.
