+# API Reference
+
+This section contains the complete API documentation for mt5cli.
+
+## Modules
+
+The mt5cli package consists of the following modules:
+
+### [CLI](cli.md)
+
+Command-line interface module providing typer-based commands for exporting MetaTrader 5 data to CSV, JSON, Parquet, and SQLite3 formats.
+
+## Architecture Overview
+
+The package follows a simple architecture built on top of pdmt5:
+
+1. **CLI Layer** (`cli.py`): Typer application with subcommands for each data type, custom Click parameter types for datetime/timeframe/tick flags parsing, and format detection/export utilities.
+2. **Data Layer** (via `pdmt5`): Uses `Mt5DataClient` and `Mt5Config` from the pdmt5 package for all MetaTrader 5 data access.
+
+## Usage Guidelines
+
+All modules follow these conventions:
+
+- **Type Safety**: All functions include comprehensive type hints
+- **Error Handling**: User-friendly error messages via typer
+- **Documentation**: Google-style docstrings with examples
+- **Validation**: Custom Click parameter types for input validation
+
+## Quick Start
+
+```bash
+# Export account information to CSV
+mt5cli -o account.csv account-info
+
+# Export EURUSD H1 rates to Parquet
+mt5cli -o rates.parquet rates-from --symbol EURUSD --timeframe H1 \
+  --date-from 2024-01-01 --count 1000
+
+# Export ticks to JSON
+mt5cli -o ticks.json ticks-from --symbol EURUSD \
+  --date-from 2024-01-01 --count 500 --flags ALL
+
+# Export to SQLite3 with custom table name
+mt5cli -o data.db --table symbols symbols --group "*USD*"
+```
+
+## Python API
+
+```python
+from mt5cli import detect_format, export_dataframe
+import pandas as pd
+
+# Detect output format from file extension
+fmt = detect_format(Path("output.parquet"))  # Returns "parquet"
+
+# Export a DataFrame
+df = pd.DataFrame({"symbol": ["EURUSD"], "bid": [1.1234]})
+export_dataframe(df, Path("output.csv"), "csv")
+```
+
