## 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-3c28934a
```

Example prompt: What's the current price of Wrapped Bitcoin and Coinbase Wrapped BTC? Use their coingecko IDs — coingecko:wrapped-bitcoin and coingecko:coinbase-wrapped-btc.

## When to prefer this

Use this endpoint when you need current token prices for one or more coins identified by CoinGecko slug or EVM contract address, especially in a DeFi or crypto-native context. Prefer over raw CoinGecko or CoinMarketCap APIs when you want a pay-per-call model with no persistent API key and USDC micropayment settlement on Base.

## Known failure modes

- Invalid or unrecognized coin identifier returns empty or null price entry
- Malformed coin identifier format causes 400-level error
- Network or upstream DeFiLlama outage returns 5xx
- Exceeding rate limits or payment failure may return 402 or 429
- Comma-separated list with whitespace may fail parsing

## 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 current USD prices for each requested coin identifier, keyed by the identifier string (e.g. coingecko:bitcoin → price in USD). May include additional metadata depending on the DeFiLlama response structure.
