# **PriceHub**: Unified Python Package for Collecting OHLC Prices from Binance, Bybit, Coinbase, OKX, Kraken, KuCoin, and Bitget APIs into a DataFrame

It supports multiple markets, including spot and futures, and provides flexible timestamp inputs and a wide range of intervals.

Effective trading begins with thorough data analysis, visualization, and backtesting. This package simplifies access to such data, providing a unified solution for retrieving OHLC information across various broker APIs.

📚 **Full documentation:** [https://eslazarev.github.io/pricehub/](https://eslazarev.github.io/pricehub/)

## Quickstart

```bash
pip install pricehub
```

```python
from pricehub import get_ohlc

# One call, any exchange → a ready-to-use pandas DataFrame
df = get_ohlc("binance_spot", "BTCUSDT", "1d", "2024-10-01", "2024-10-05")
print(df)
```

Same call signature for every supported exchange and market — just change the broker:

```python
get_ohlc("bybit_linear",   "ETHUSDT",  "1h", "2024-10-01", "2024-10-02")
get_ohlc("okx_futures",    "BTC-USDT", "4h", "2024-10-01", "2024-10-02")
get_ohlc("kraken_spot",    "XBTUSDT",  "1d", "2024-10-01", "2024-10-05")
```

No API keys required for public market data. Large date ranges are paginated automatically.

## Why PriceHub?

Need OHLC candles from several crypto exchanges in Python? You *could* wire up each exchange SDK yourself, or wrangle a heavier general-purpose library. PriceHub does one thing well: **a single function that returns a clean `pandas.DataFrame` from any supported exchange.**

| | **PriceHub** | `ccxt` | single-exchange SDKs<br>(`python-binance`, …) |
|---|:---:|:---:|:---:|
| Unified interface across 7 exchanges | ✅ | ✅ | ❌ (one exchange each) |
| Returns a `pandas.DataFrame` directly | ✅ | ❌ (list of lists) | ❌ (raw JSON) |
| Pagination over large date ranges | ✅ (default) | ⚙️ (opt-in `paginate`) | ❌ (manual) |
| All raw fields from the official API | ✅ | ❌ (OHLCV only) | ✅ |
| No API keys for public data | ✅ | ✅ | ✅ |
| Lightweight dependencies | ✅ (4) | ❌ (more) | varies |
| Focused scope (OHLC only) | ✅ | ❌ (full trading) | ❌ (full trading) |

**Use PriceHub when** you need historical/recent OHLC data for backtesting, research, ML datasets, or dashboards — without per-exchange boilerplate.
**Reach for `ccxt`** when you need full trading functionality (placing orders, balances, websockets) across dozens of venues.

## Maintenance

PriceHub is actively maintained. Issues and pull requests are typically reviewed within one week.

- **Daily live checks**: A scheduled GitHub Actions workflow ([`providers-health.yml`](.github/workflows/providers-health.yml)) hits every supported exchange API once per day with a small sample request and verifies real data is returned. Current status is reflected in the **Providers Health** badge above.

- **Versioning**: [Semantic Versioning 2.0](https://semver.org/). Breaking changes will only land in major releases.
- **Python support**: All non-end-of-life Python versions (currently 3.8 through 3.13). End-of-life Python versions are dropped in the next minor release after they reach EOL.
- **Dependency policy**: Direct dependencies are kept minimal (`pandas`, `pydantic`, `arrow`, `requests`). New dependencies are added only when they enable a feature that cannot be reasonably implemented in-tree.
- **API stability**: The public surface (`get_ohlc`, broker identifiers, supported intervals) follows SemVer. Returned DataFrame column names mirror upstream exchange APIs and may change if an exchange renames fields — such changes are documented in release notes.
- **Reporting issues**: See [GitHub Issues](https://github.com/eslazarev/pricehub/issues). For security-sensitive reports, email `elazarev@gmail.com` directly.
