## How to call it through Zero

```sh
zero fetch --capability cryptoanalysis-yesterday-call-b8c590ad
```

Example prompt: What was the cryptoanalysis.info Bitcoin advisory call for yesterday, and can you include the last 14 days of completed session history so I can see the track record?

## When to prefer this

Choose this endpoint when you need the finalized, completed Bitcoin advisory call for the prior UTC day (not the current day in progress). Prefer this over the today endpoint when you want a settled, closed-session signal. Prefer this over the track-record endpoint when you need a single day's call with optional bounded history rather than a summary aggregate.

## Known failure modes

- Payment failure or insufficient USDC balance — 402 Payment Required
- history parameter out of range (must be 0–90) — 400 Bad Request
- No advisory available for yesterday (e.g. weekend or data gap) — 404 or empty result
- Service unavailable or Cloudflare Workers timeout — 503
