> CRYPTYX Thesis Journal — Daily Asset Conviction History is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Returns a day-by-day history of an asset's composite score, macro regime, signal count, and dominant factor class to track how conviction has evolved over time.

## 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-daily-asset-conviction-history-2305676c
```

Example prompt: Pull the CRYPTYX thesis journal for BTC over the last 60 days — I want to see the daily composite score, macro regime label, and signal count for each day so I can study how conviction built up before the recent move.

## When to prefer this

Use this endpoint when you need to study how an asset's conviction, regime, and signal activity evolved day by day over a historical window — particularly useful for pre-trade analysis, backtesting narratives, or understanding what signals preceded a major price move. Prefer this over the current regime endpoint when historical context matters, not just the current state.

## Known failure modes

- Missing or invalid symbol returns an error indicating the asset is not found or not covered in the ~200-asset universe
- Lookback days value out of acceptable range may return an empty array or validation error
- No data available for requested date range returns an empty entries array
- Service unavailable or payment not processed returns a 402 or 5xx error
- Symbol provided in wrong format (e.g. lowercase when uppercase required) may return no results

## How this service works

CRYPTYX | institutional-grade crypto intelligence: 150+ signals, 440+ metrics, 200+ assets. | Per-day composite conviction trajectory for one asset across a 7-90 day window. Reads metrics.composite for the score timeline and LEFT JOINs analytics.asset_thesis_daily for optional one-liner overlay (direction + one_liner + generated_at). Returns ok, symbol, days, points[] with {d, composite, direction, one_liner, generated_at}, thesis_count, and a note flagging when the thesis populate job has not yet written rows. Score timeline is always complete; narrative overlay is honest about gaps. Use to track conviction evolution before a major move.

## Output

A JSON array of daily entries, each containing the date, composite conviction score, macro regime label (e.g. 'expansion'), and the number of atomic signals that fired on that day — covering up to the requested lookback window.
