## 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`):

## When to prefer this

Use this endpoint when you need aggregated, structured data on public company Bitcoin treasury holdings sourced from SEC filings, rather than raw on-chain data or generic crypto price feeds. Prefer this over general BTC market endpoints when the user's question is specifically about institutional or corporate BTC accumulation.

## Known failure modes

- Missing or invalid 'briefing' query parameter returns a 400 error
- Date outside allowed historical range for the user's tier returns an access error
- Invalid date format (not YYYY-MM-DD) returns a validation error
- Payment not processed (x402 protocol failure) returns a 402 Payment Required
- Upstream SEC or CoinGecko data unavailable may return stale or incomplete context

## How this service works

## Output

A structured briefing containing context text about corporate Bitcoin treasury holdings, metrics with signals and confidence scores, the briefing ID (btc.treasury), and a generated_at timestamp — available as JSON or token-optimized markdown.
