Integrate graph2table in your application

Automate your data extraction workflows and build powerful custom tools with our simple and robust API.

Our API provides direct access to our state-of-the-art AI plot digitization engine. By integrating it, you can programmatically send graph images and receive structured JSON data in return, perfect for research pipelines, data analysis applications, and automated reporting systems.

API keys

Create and manage your API keys from the API keys page in your account. Each key is shown once at creation, so copy it somewhere safe.

Python example

Every request costs 10 credits. You can optionally send custom_instructions for per-upload guidance.

import requests

# Load an example graph image
image_url = 'https://graph2table.com/static/img/line_chart_example.png'
image_file = requests.get(image_url, stream=True).content

# Prepare the request
api_url = 'https://graph2table.com/api/v1/convert'
files = {'file': ('example.png', image_file, 'image/png')}
data = {
    'custom_instructions': 'Extract only the red data series',  # optional
}
headers = {'Authorization': 'Bearer YOUR_API_KEY'}

# Complete the request
api_response = requests.post(api_url, headers=headers, files=files, data=data, timeout=180)

Errors

Requests that fail return a JSON body of the form {"error": "..."} alongside the status code below.

If the AI cannot read the uploaded image (for example it is not a graph, or the plot is too unclear to extract), the request also returns 422 with a message explaining what went wrong, so you can surface it to your users.
