Installation

Prerequisites

• Python 3.14 or higher
• uv package manager

Setup

git clone https://github.com/vsharha/multi-ai-handler.git
cd multi-ai-handler
uv sync

Setup

1. Create a .env file

Create a .env file in your project root with your API keys:

ANTHROPIC_API_KEY=your_anthropic_api_key_here
GEMINI_API_KEY=your_gemini_api_key_here
OPENROUTER_API_KEY=your_openrouter_api_key_here

2. Import the library

from multi_ai_handler import (
    request_ai,
    request_anthropic,
    request_google,
    request_openai,
    request_openrouter,
    Providers
)

Usage

Text-only requests

from multi_ai_handler import request_anthropic

response = request_anthropic(
    system_prompt="You are a helpful assistant.",
    user_text="What is the capital of France?",
    model="claude-3-5-sonnet-20241022",
    temperature=0.7
)
print(response)

Image analysis

from multi_ai_handler import request_google

# Simply pass the file path
response = request_google(
    system_prompt="You are an image analysis expert.",
    user_text="Describe what you see in this image.",
    file="image.jpg",
    model="gemini-1.5-flash",
    temperature=0.0
)
print(response)

Document processing

from multi_ai_handler import request_anthropic

# Pass the PDF file path
response = request_anthropic(
    system_prompt="You are a document analysis assistant.",
    user_text="Summarize the key points from this document.",
    file="document.pdf",
    model="claude-3-5-sonnet-20241022",
    temperature=0.0
)
print(response)

File-only requests (no text)

from multi_ai_handler import request_google

# User text can be None when only analyzing a file
response = request_google(
    system_prompt="Extract all text and data from images.",
    file="chart.png",
    model="gemini-1.5-pro"
)
print(response)

Using pathlib.Path

from multi_ai_handler import request_anthropic
from pathlib import Path

response = request_anthropic(
    system_prompt="Analyze this document.",
    file=Path("documents/report.pdf"),
    model="claude-3-5-sonnet-20241022"
)
print(response)

Using pre-encoded data

from multi_ai_handler import request_google
import base64

# If you already have encoded data
with open("image.jpg", "rb") as f:
    encoded_data = base64.b64encode(f.read()).decode()

response = request_google(
    system_prompt="Describe this image.",
    file={"filename": "image.jpg", "encoded_data": encoded_data},
    model="gemini-1.5-flash"
)
print(response)

Unified interface with JSON output

The library provides a unified request_ai() function that automatically routes to the appropriate provider and supports JSON output parsing:

from multi_ai_handler import request_ai, Providers

# Basic usage with default provider (Google)
response = request_ai(
    system_prompt="You are a helpful assistant.",
    user_text="What is the capital of France?",
    temperature=0.7
)
print(response)

# Specify a provider and model
response = request_ai(
    system_prompt="You are a data extraction expert.",
    user_text="Extract key information from: John Doe, age 30, lives in NYC",
    provider=Providers.ANTHROPIC,
    model="claude-sonnet-4-5-20250929",
    temperature=0.0
)
print(response)

# Request JSON output - automatically parses response
data = request_ai(
    system_prompt="You are a JSON formatter. Return valid JSON only.",
    user_text="Convert to JSON: Name: Alice, Age: 25, City: London",
    provider="google",
    json_output=True
)
print(data)  # Returns parsed dict

JSON Output Parsing:

• When json_output=True, the function automatically extracts and parses JSON from the response
• Handles responses wrapped in markdown code blocks (json ... )
• Returns a Python dictionary
• Raises an exception if JSON parsing fails

API Reference

Common Parameters

All request functions share the following parameters:

• system_prompt (str, required): The system instruction for the AI model
• user_text (str, optional): The user's text input
• file (str | Path | dict, optional): File to process. Can be:
  • File path: "image.jpg" or Path("image.jpg") - automatically reads and encodes
  • Dict: {"filename": "image.jpg", "encoded_data": "base64..."} - for pre-encoded data
• model (str, required): The specific model to use
• temperature (float, optional): Controls randomness (0.0 = deterministic, 1.0 = creative). Default: 0.0

Note: Either user_text or file must be provided.

request_anthropic()

Makes a request to Anthropic's Claude API with streaming support.

def request_anthropic(
    system_prompt: str,
    user_text: str = None,
    file: str | Path | dict = None,
    model: str = None,
    temperature: float = 0.0
) -> str

Supported file types: Images (PNG, JPEG, GIF, WebP), Documents (PDF, DOCX, TXT, etc.)

request_google()

Makes a request to Google's Gemini API with token usage reporting.

def request_google(
    system_prompt: str,
    user_text: str = None,
    file: str | Path | dict = None,
    model: str = None,
    temperature: float = 0.0
) -> str

Supported file types: Images, videos, audio, documents

Note: Prints token usage (prompt, output, and total tokens) to console.

request_openai()

Makes a request to OpenAI's API.

def request_openai(
    system_prompt: str,
    user_text: str = None,
    file: str | Path | dict = None,
    model: str = None,
    temperature: float = 0.0,
    link: str = None
) -> str

Supported file types: Images (PNG, JPEG, GIF, WebP), PDFs (via file API)

Additional parameter:

• link (str, optional): Custom base URL for API endpoint

request_openrouter()

Makes a request through OpenRouter's unified API.

def request_openrouter(
    system_prompt: str,
    user_text: str = None,
    file: str | Path | dict = None,
    model: str = None,
    temperature: float = 0.0
) -> str

Uses OpenAI-compatible format. Requires OPENROUTER_API_KEY in environment.

request_ai() (Unified Interface)

Unified function that automatically routes to the appropriate provider with built-in JSON parsing support.

def request_ai(
    system_prompt: str,
    user_text: str = None,
    file: str | Path | dict = None,
    provider: str | Providers | None = None,
    model: str | None = None,
    temperature: float = 0.2,
    json_output: bool = False
) -> str | dict

Parameters:

• All common parameters (system_prompt, user_text, file, temperature)
• provider (str | Providers, optional): Provider to use. Defaults to Google Gemini
• model (str, optional): Model to use. Defaults to first supported model for the provider
• json_output (bool, optional): If True, parses and returns JSON as dict. Default: False

Returns:

• str if json_output=False
• dict if json_output=True

Supported Providers Enum:

• Providers.GOOGLE
• Providers.ANTHROPIC
• Providers.OPENAI
• Providers.OPENROUTER

Payload Generation

The library automatically formats payloads for each provider using specialized functions:

• generate_openai_payload(): Creates OpenAI-compatible content blocks
• generate_gemini_payload(): Creates Gemini-compatible parts
• generate_claude_payload(): Creates Claude-compatible content blocks

These functions handle:

• MIME type detection from filenames
• Base64 data URL formatting
• Provider-specific content structure
• Validation of required inputs

Error Handling

The library raises errors in the following cases:

• ValueError: Neither user_text nor file is provided
• ValueError: MIME type cannot be detected from filename
• FileNotFoundError: File path provided but file doesn't exist
• ValueError: Path provided is not a file (e.g., is a directory)
• Invalid API credentials

Example:

from multi_ai_handler import request_anthropic

try:
    response = request_anthropic(
        system_prompt="You are helpful.",
        file="document.pdf",
        model="claude-3-5-sonnet-20241022"
    )
except FileNotFoundError as e:
    print(f"File not found: {e}")
except ValueError as e:
    print(f"Error: {e}")

Best Practices

1. Use specific model names: Always specify the exact model version (e.g., claude-3-5-sonnet-20241022)
2. Handle errors: Wrap API calls in try-except blocks
3. Manage API keys securely: Never commit .env files to version control
4. Optimize temperature: Use lower values (0.0-0.3) for factual tasks, higher (0.7-1.0) for creative tasks
5. Monitor token usage: Check console output for Gemini token counts
