Unstract Integration

Unstract is a no-code platform for building document extraction workflows powered by large language models. It allows teams to create APIs that automatically extract structured data from unstructured documents like invoices, contracts, and forms.

Unstract supports custom LLM providers for its extraction workflows, allowing you to connect LLM API as the AI backend.

Prerequisites

An LLM API account with an API key
Unstract installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in Unstract

Log in to your Unstract dashboard.
Navigate to the LLM Provider or Model Configuration settings.
Add a new provider and select "OpenAI Compatible".
Enter the following details:
- API Key: paste the key you copied from app.llmapi.ai/api-keys
- Base URL: https://api.llmapi.ai/v1
- Model: the model ID you wish to use (e.g., openai/gpt-4o)
Click "Save" to store the configuration.
Select LLM API as the provider when building your extraction workflows.

Test the Integration

Verify that Unstract can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

Different extraction tasks may benefit from different models. LLM API gives you the flexibility to choose the right model for each workflow.

Benefits of Using LLM API with Unstract

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
