gemini-api-toolkit 0.2.0

A robust, lightweight Python wrapper for the Google Gemini API.

Gemini API Toolkit

Python wrapper for the Google Gemini API (using the official google-genai SDK).

Comparison: Manually vs. Toolkit

The following example demonstrates a complex multimodal workflow: Processing images and a PDF to generate a structured insurance claim decision using the gemini-3-pro-preview model.

Raw SDK (Manual Implementation):

import time
import mimetypes
import pathlib
from google import genai
from google.genai import types
from pydantic import BaseModel, Field

# 1. Define Structure
class ClaimDecision(BaseModel):
    decision: str = Field(description="Approved or Denied")
    estimated_cost: float
    reasoning: str
    requires_human_review: bool

# 2. Setup Client
client = genai.Client(http_options={'api_version': 'v1alpha'})

# 3. Handle Inputs
media_files = ["front_bumper.jpg", "side_panel.jpg", "police_report.pdf"]
parts = []

for path_str in media_files:
    path = pathlib.Path(path_str)
    mime_type, _ = mimetypes.guess_type(path)
    
    if mime_type == "application/pdf":
        print(f"Uploading {path}...")
        with open(path, "rb") as f:
            # Upload
            uploaded_file = client.files.upload(file=f, config={'mime_type': mime_type})
        
        while True:
            file_meta = client.files.get(name=uploaded_file.name)
            if file_meta.state.name == "ACTIVE":
                print("File Active.")
                break
            elif file_meta.state.name == "FAILED":
                raise Exception("File upload failed")
            time.sleep(2)
            
        parts.append(types.Part(
            file_data=types.FileData(file_uri=uploaded_file.uri, mime_type=mime_type),
            media_resolution={"level": "media_resolution_high"} # PDF spec from docs
        ))
    else:
        # Inline Image
        parts.append(types.Part(
            inline_data=types.Blob(
                data=path.read_bytes(), 
                mime_type=mime_type
            ),
            media_resolution={"level": "media_resolution_high"} # Image spec from docs
        ))

# 4. Add Prompt
parts.append(types.Part(text="Analyze these images and the report to determine if the insurance claim should be approved."))

# 5. Configure Gemini 3 Specifics
generate_config = types.GenerateContentConfig(
    temperature=1.0, # Recommended default for Gem 3
    response_mime_type="application/json",
    response_schema=ClaimDecision,
    thinking_config=types.ThinkingConfig(
        thinking_level="HIGH",
        include_thoughts=True
    )
)

# 6. Generate
print("Generating...")
response = client.models.generate_content(
    model="gemini-3-pro-preview",
    contents=[types.Content(parts=parts)],
    config=generate_config
)

# 7. Parse Result
if response.parsed:
    print(response.parsed)
else:
    print(response.text)

With Gemini API Toolkit:

from pydantic import BaseModel, Field
from gemini_kit import prompt_gemini_3

# 1. Define Structure
class ClaimDecision(BaseModel):
    decision: str = Field(description="Approved or Denied")
    estimated_cost: float
    reasoning: str
    requires_human_review: bool

# 2. Define Inputs
media = ["front_bumper.jpg", "side_panel.jpg", "police_report.pdf"]
prompt_text = "Analyze these images and the report to determine if the insurance claim should be approved."

# 3. Call the Function
result, tokens = prompt_gemini_3(
    model="gemini-3-pro-preview",
    prompt=prompt_text,
    media_attachments=media,
    response_schema=ClaimDecision,
    media_resolution="high", 
)

print(result)

Installation

Using Pip:

pip install gemini-api-toolkit

From Source:

git clone https://github.com/Danielnara24/gemini-api-toolkit.git
cd gemini-api-toolkit
pip install -e .

Usage

1. Basic Text & Google Search

from gemini_kit import prompt_gemini

prompt = "What are the latest specs of the Steam Deck OLED vs the ROG Ally X?"

response, tokens = prompt_gemini(
    model="gemini-2.5-flash",
    prompt=prompt,
    google_search=True,  # Enables Search Tool
    thinking=True        # Enables Thinking
)

print(response)

2. Mixed Media (Video, PDF, Images)

Pass local file paths or YouTube URLs. The kit handles upload/inline logic automatically.

from gemini_kit import prompt_gemini

files = ["./downloads/tutorial.mp4", "./documents/specification.pdf"]

response, tokens = prompt_gemini(
    model="gemini-2.5-pro",
    prompt="Compare the specifications in the PDF with the device shown in the video.",
    media_attachments=files
)

print(response)

3. Gemini 3: Search + Code + JSON

from pydantic import BaseModel
from gemini_kit import prompt_gemini_3

class CryptoRatio(BaseModel):
    btc_price: float
    eth_price: float
    ratio: float
    summary: str

response_obj, tokens = prompt_gemini_3(
    prompt="Find current BTC and ETH prices and calculate the ETH/BTC ratio.",
    response_schema=CryptoRatio, 
    google_search=True,
    code_execution=True,
    thinking_level="high"
)

print(f"Ratio: {response_obj.ratio} | Summary: {response_obj.summary}")

4. Cleanup

Free up server storage space (deletes files uploaded via Files API).

from gemini_kit import delete_all_uploads

delete_all_uploads()

Arguments

• model: The name of the Gemini model to use (e.g., "gemini-2.5-flash", "gemini-3-pro-preview").
• prompt: The text instruction sent to the model.
• response_schema: Pydantic model or Enum class to enforce structured JSON output.
• media_attachments: List of file paths (images, videos, PDFs) or YouTube URLs to analyze.
• upload_threshold_mb: Files larger than this (in MB) are uploaded via Files API; smaller are sent inline.
• thinking_level: Controls reasoning depth for Gemini 3 ("low" or "high").
• thinking: Boolean to enable/disable the thinking process for Gemini 2.5.
• media_resolution: Sets token usage/quality for inputs ("low", "medium", "high") for Gemini 3.
• temperature: Controls output randomness (0.0 to 2.0).
• google_search: Boolean to enable Grounding with Google Search.
• code_execution: Boolean to enable the Python code interpreter tool.
• url_context: Boolean to enable the model to read/process content from URLs in the prompt.
• max_retries: Number of times to retry the API call if it fails. 0 by default
