## 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-1a0426e7
```

Example prompt: What are the current prices of AAVE and Curve DAO Token? Look them up using coingecko:aave and coingecko:curve-dao-token.

## When to prefer this

Choose this endpoint when you need real-time token prices for one or more crypto assets identified by CoinGecko slugs or ERC-20 contract addresses, especially in DeFi contexts where DeFiLlama pricing data is preferred. Ideal for multi-token price lookups in a single call. Prefer over exchange-specific price APIs when you need broad DeFi token coverage including long-tail assets.

## Known failure modes

- Invalid or unrecognized coin identifier returns error or missing data
- Malformed contract address returns lookup failure
- Rate limiting or upstream DeFiLlama unavailability returns 5xx
- Too many coins in a single request may cause truncation or timeout
- Payment not settled in USDC causes 402 rejection

## 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:aave, coingecko:curve-dao-token or an Ethereum contract address).
