## 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-bfd4a53e
```

Example prompt: What are the current USD prices for Bitcoin, Ethereum, and Solana right now?

## When to prefer this

Use this endpoint when you need current spot prices for one or more crypto tokens and can identify them by CoinGecko slug (e.g. coingecko:bitcoin) or by chain:contract format. Prefer this over on-chain oracles when you need a quick aggregated USD price without smart contract interaction. It supports batch lookups in a single call, making it efficient for multi-token price checks.

## Known failure modes

- Unknown or misspelled coin identifier returns no price for that token
- Invalid chain prefix causes lookup failure for contract-address-style identifiers
- Rate limiting or payment failure returns 402 or 429 error
- Empty coins path parameter returns error or empty response
- Network timeout if DefiLlama upstream is slow

## 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 JSON object containing current USD prices keyed by coin identifier (e.g. coingecko:bitcoin, coingecko:ethereum), with price values and likely timestamps from DefiLlama's aggregated price feed.
