## 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-bitcoin-grid-stress-api-216e115b
```

Example prompt: Pull me the btc.grid-stress briefing from PreReason in markdown format so I can see the current Bitcoin epoch pace, difficulty adjustment forecast, and miner pressure signals for today.

## When to prefer this

Use this endpoint when you specifically need Bitcoin mining network health data — epoch progression, difficulty adjustment outlook, and miner financial stress — rather than general price or macro context. Prefer this over btc.miner-survival for grid/epoch timing focus, and over btc.pulse for mining-specific signals rather than mempool or fee data.

## Known failure modes

- Missing required 'briefing' query parameter returns a 400 validation error
- Invalid briefing ID enum value returns a 400 bad request
- Date outside the tier's allowed historical range returns a 403 or 402 payment required
- Payment not provided or invalid returns a 402 Payment Required (x402)
- Server-side data unavailability for the requested date returns a 503 or 404
- Invalid date format (not YYYY-MM-DD) returns a 400 error

## How this service works

PreReason delivers market context for financial agents. Bitcoin on-chain metrics, macro indicators, and reasoning context in one API call.

## Output

Returns a JSON or markdown document containing Bitcoin grid stress context: epoch pace, estimated difficulty adjustment percentage, miner production cost vs price pressure, and directional signals (bullish/bearish/neutral) with confidence scores and a generated_at timestamp.
