## 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 claw402-alpaca-latest-bars-x402-f1d23bd4
```

Example prompt: Get me the latest bar data for AAPL and TSLA from the Alpaca feed — I want the most recent OHLCV snapshot for both symbols.

## When to prefer this

Choose this endpoint when you need the latest single OHLCV bar for one or more stock or crypto symbols via Alpaca market data, and you want to pay per-call with USDC without registering for an API key — ideal for lightweight, wallet-based agent workflows that need current price snapshots.

## Known failure modes

- Invalid or unsupported symbol returns empty data array
- Missing required 'symbols' query parameter causes error
- Payment failure or insufficient USDC balance blocks the request
- Unsupported feed or currency enum value may cause rejection
- Market closed or no recent bar available may return empty results
