## 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 prereason-market-context-api-full-bitcoin-briefing-5e363f1d
```

Example prompt: Can you pull the full Bitcoin briefing from PreReason — the btc.full one — for today in JSON format? I want to see on-chain, macro, energy, and cross-asset data all in one shot.

## When to prefer this

Choose this endpoint when you need the broadest possible Bitcoin market context in a single API call — covering on-chain, macro, energy, and cross-asset data simultaneously. Prefer it over narrower briefings (btc.on-chain, macro.snapshot, btc.energy) when you want a holistic view without making multiple requests. Best for comprehensive market analysis, daily briefings, or when building dashboards that require the full context picture.

## Known failure modes

- Invalid briefing ID returns 400 bad request
- Date outside tier access range returns 403 or 402 payment required
- Payment not provided or invalid returns 402
- Invalid date format (not YYYY-MM-DD) returns 400
- Data unavailable for requested historical date returns 404 or empty result
- Network timeout returns 5xx
