## 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-ai-defillama-token-price-lookup-df76aea4
```

Example prompt: What are the current prices for Ocean Protocol and SingularityNET? Use coingecko:ocean-protocol and coingecko:singularitynet as the coin identifiers.

## When to prefer this

Use this endpoint when you need fast, low-cost spot price lookups for one or more crypto tokens identifiable by coingecko slug or EVM contract address, especially when working within a Web3/x402 payment context. Prefer this over exchange-specific APIs when you need cross-chain token coverage via DefiLlama aggregation.

## Known failure modes

- Invalid coin identifier format returns empty or error response
- Unknown coingecko slug or contract address yields no price data
- Malformed comma-separated list may cause partial or failed lookups
- Network or upstream DefiLlama API unavailability returns 5xx error
- Payment not completed (x402) blocks access to the endpoint

## 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

A map of coin identifiers to their current USD prices, sourced from DefiLlama's price aggregation layer. Each entry keyed by the coin identifier (e.g. coingecko:bitcoin) with price value.
