# Guidelinely Python Client

[![Python 3.9+](https://img.shields.io/badge/python-3.9+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

Python client library for the [Guidelinely API](https://guidelines.1681248.com/docs) - an environmental guideline calculation and search API.

Calculate context-dependent environmental guideline values for chemical parameters (Aluminum, Copper, Lead, etc.) in various media (water, soil, sediment) based on environmental conditions (pH, hardness, temperature, etc.).

This Python client mirrors the functionality of the [R client](https://github.com/mpdavison/envguidelines).

## Features


- ✅ **Metadata Queries**: List parameters, search, explore media types and sources
- ✅ **Single Calculations**: Calculate guidelines for individual parameters
- ✅ **Batch Calculations**: Efficiently calculate multiple parameters (up to 50)
- ✅ **Context-Aware**: Support for pH, hardness, temperature, and other environmental factors
- ✅ **Unit Conversion**: Optional target unit specification
- ✅ **Type Safety**: Full Pydantic model support for request/response validation
- ✅ **Comprehensive Tests**: Mock-based test suite with responses library

## Installation

```bash
# Clone the repository
git clone https://github.com/mpdavison/guidelinely-python.git
cd guidelinely-python

# Install in development mode
pip install -e .

# Or install with dev dependencies
pip install -e ".[dev]"
```

## Quick Start

```python
from guidelinely import calculate_guidelines

# Calculate aluminum guidelines in surface water
result = calculate_guidelines(
    parameter="Aluminum",
    media="surface_water",
    context={
        "pH": "7.0 1",           # pH 7.0 (dimensionless)
        "hardness": "100 mg/L"   # Water hardness as CaCO3
    }
)

print(f"Found {result.total_count} guidelines")
for guideline in result.results:
    print(f"{guideline.parameter}: {guideline.value} ({guideline.source})")
```

## API Key

Calculation endpoints optionally accept an API key. Set it as an environment variable:

```bash
export GUIDELINELY_API_KEY="your_api_key_here"
```

Metadata endpoints (list parameters, search, etc.) work without authentication.

## Usage Examples

### Basic Metadata Queries

```python
from guidelinely import (
    health_check,
    list_parameters,
    search_parameters,
    list_media,
    list_sources,
    get_stats,
)

# Check API health
status = health_check()

# List all chemical parameters
params = list_parameters()
print(f"Available parameters: {len(params)}")

# Search for ammonia-related parameters
ammonia = search_parameters("ammon")
print(ammonia)  # ['Ammonia', 'Ammonium', ...]

# Get available media types
media = list_media()
# {'surface_water': 'Surface Water', 'soil': 'Soil', ...}

# View guideline sources
sources = list_sources()

# Database statistics
stats = get_stats()
```

### Single Parameter Calculation

```python
from guidelinely import calculate_guidelines
import os

os.environ["GUIDELINELY_API_KEY"] = "your_key"

result = calculate_guidelines(
    parameter="Copper",
    media="surface_water",
    context={
        "pH": "7.5 1",
        "hardness": "150 mg/L",
        "temperature": "15 °C",
        "chloride": "75 mg/L"
    },
    target_unit="μg/L"  # Optional unit conversion
)

# Filter results
chronic_aquatic = [
    g for g in result.results
    if g.receptor == "Aquatic Life" and g.exposure_duration == "chronic"
]
```

### Batch Calculations

```python
from guidelinely import calculate_batch

# Calculate multiple parameters at once (more efficient)
result = calculate_batch(
    parameters=["Aluminum", "Copper", "Lead", "Zinc", "Cadmium"],
    media="surface_water",
    context={
        "pH": "7.5 1",
        "hardness": "150 mg/L",
        "temperature": "15 °C"
    }
)

print(f"Total: {result.total_count} guidelines")

# With per-parameter unit conversion
result = calculate_batch(
    parameters=[
        "Aluminum",
        {"name": "Copper", "target_unit": "μg/L"},
        {"name": "Lead", "target_unit": "mg/L"}
    ],
    media="surface_water",
    context={"pH": "7.0 1", "hardness": "100 mg/L"}
)
```

### Soil Calculations

```python
result = calculate_guidelines(
    parameter="Lead",
    media="soil",
    context={
        "pH": "6.5 1",
        "organic_matter": "3.5 %",
        "cation_exchange_capacity": "15 meq/100g"
    }
)
```

## Environmental Context Parameters

All context parameters **must be strings with units** (Pint format):

### Water (surface_water, groundwater)
```python
context = {
    "pH": "7.0 1",           # Dimensionless - use "1" as unit
    "hardness": "100 mg/L",  # mg/L as CaCO3
    "temperature": "20 °C",
    "chloride": "50 mg/L"
}
```

### Soil
```python
context = {
    "pH": "6.5 1",
    "organic_matter": "3.5 %",
    "cation_exchange_capacity": "15 meq/100g"
}
```

### Sediment
```python
context = {
    "pH": "7.0 1",
    "organic_matter": "2.5 %",
    "grain_size": "0.5 mm"
}
```

## Data Models

The library uses Pydantic for type-safe data handling:

```python
from guidelinely.models import GuidelineResponse, CalculationResponse

# All API responses are strongly typed
result: CalculationResponse = calculate_guidelines(...)

# Access typed fields
for guideline in result.results:
    guideline.parameter  # str
    guideline.value      # str (PostgreSQL unitrange format)
    guideline.lower      # Optional[float]
    guideline.upper      # Optional[float]
    guideline.unit       # str
    guideline.is_calculated  # bool
```

## Guideline Value Format

Guidelines use PostgreSQL `unitrange` format:
- `[10 μg/L,100 μg/L]` - Range from 10 to 100 μg/L
- `(,87.0 μg/L]` - Upper limit only (≤87.0 μg/L)
- `[5.0 mg/L,)` - Lower limit only (≥5.0 mg/L)

Parsed into `lower`, `upper`, and `unit` fields.
