This guide walks you through making your first document processing request. By the end, you’ll have sent a document and received structured data back.

​
What you need

  1. A Matil account — sign up here
  2. An API key
  3. A deployment ID
Don’t have these yet? Follow the steps below.

​
Get your API key

1

Open the dashboard

Log in to the Matil Dashboard and go to Settings > API Keys.
2

Create a new key

Click Create New Key. Give it a name that helps you identify its purpose (e.g., “Development” or “Production”).
3

Copy the key

Copy your API key immediately — it won’t be shown again.
Store your API key in an environment variable. Never hardcode it in your source code or commit it to version control.

​
Find your deployment ID

Go to Deployments in the dashboard. Select the deployment you want to use and copy its ID. A deployment ID is a UUID like: 01234567-89ab-cdef-0123-456789abcdef
If you don’t have a deployment yet, create one in the dashboard first. A deployment defines what data you want to extract and from which type of document.

​
Make your first request

Send a document to your deployment: 
curl -X POST "https://api.matil.ai/v3/deployments/{your-deployment-id}" \
  -H "x-api-key: your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "documents": [
      {
        "type": "url",
        "url": "https://example.com/invoice.pdf"
      }
    ]
  }'

​
Understand the response

A successful response looks like this: 
{
  "entry_id": "01934b1a-89ab-7def-0123-456789abcdef",
  "resource_type": "structure",
  "resource_id": "01934b1a-1234-7abc-0000-111122223333",

  "data": {
    "invoice_number": "INV-2024-001",

    "total": 150.00
  },
  "errors": null,
  "status": "completed",
  "time_ms": 2340,
  "price": 0.05
}
