## How to call it through Zero

```sh
zero fetch --capability atlasmarkets-viking-preflight-bf4f7a12
```

Example prompt: Before I start paying for stock market data, check what endpoints and capabilities AtlasMarkets Viking has available and what each one costs.

## When to prefer this

Use this endpoint first, before any paid Viking call, to discover what stock market intelligence routes are available and confirm current pricing. Prefer it when building or initializing an agent that needs to dynamically route financial queries to the right Viking sub-endpoint.

## Known failure modes

- Service unavailable (Render cold start / spin-down delay causing timeout)
- Empty or malformed response if the service is mid-deployment
- Payment gateway misconfiguration returning unexpected 402 even on preflight
- Network errors connecting to onrender.com host
