## 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 cryptyx-thesis-journal-d5f1fb3d
```

Example prompt: Pull the CRYPTYX thesis journal for BTC over the last 30 days — I want to see the daily thesis scores, what regime it was in each day, and how many signals fired.

## When to prefer this

Use this endpoint when you need a time-series view of how an asset's thesis score and market regime have evolved day by day, including signal activity counts. Ideal for backtesting context, narrative building around market cycles, or monitoring how an asset's intelligence score has trended over a configurable lookback window.

## Known failure modes

- Missing required 'symbol' parameter returns validation error
- Unknown or unsupported asset symbol returns empty or 404 response
- Excessively large 'days' lookback may return partial data or timeout
- Payment not fulfilled via x402 returns 402 Payment Required
- Invalid data types for parameters return 400 Bad Request

## How this service works

Per-day composite conviction trajectory for one asset over 7-90 days. Score timeline always complete; optional narrative one-liner overlay from the daily thesis job. Track conviction evolution before a major move. Coverage: pass any asset in the CRYPTYX 200+ tracked universe (BTC, ETH, SOL, top-cap + long-tail).

## Output

An array of daily journal entries, each containing the date, a thesis score (0–1 float), a market regime label (e.g. 'expansion'), and the count of signals that fired that day for the requested asset.
