## 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-market-history-88a6424d
```

Example prompt: Pull the last 90 days of market history for BTC from CRYPTYX — I need the daily open, high, low, close, and volume data.

## When to prefer this

Use this endpoint when you need structured historical OHLCV price data for a specific cryptocurrency over a defined time window (up to 365 days). It is well-suited for backtesting, charting, trend analysis, or generating price summaries. Prefer this over real-time ticker endpoints when historical patterns rather than current prices are needed.

## Known failure modes

- Invalid or unsupported asset symbol returns an error or empty dataset
- days parameter exceeds 365 — API likely rejects or caps the request
- Missing required parameters (asset or days) result in a 400-level error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Rate limiting or service downtime may return 429 or 5xx errors

## How this service works

Daily OHLCV bars for one asset over 1-1825 days — open, high, low, close, USD volume. UTC-1 anchor day. The grounded spot tape behind every CRYPTYX factor score and signal. Coverage: pass any asset in the CRYPTYX 200+ tracked universe (BTC, ETH, SOL, top-cap + long-tail).

## Output

An array of daily records for the requested asset, each containing date, open, high, low, close prices, and trading volume. For example, a BTC record might show date '2026-04-25', open 67000, high 68500, low 66500, close 68000, volume 1200000000.
