Invoice OCR API Pricing and Cost per Scan

What Drives OCR Cost

OCR pricing differs by whether failed requests are billed, whether credits expire, minimum monthly commitments, and the price per document type. Those terms matter more than the headline rate.

How StructOCR Prices It

Each successful invoice request costs 3 credits. Credits are prepaid from $5, never expire, and are only deducted for successful (200 OK) responses. See the full pricing page and start with 200 free credits.

Where This Fits

• Pilot: 200 free credits cover a realistic test on your own images before you pay anything.
• Steady volume: Larger packages lower the cost per credit, and unused credits carry over indefinitely.
• Enterprise: Contact sales for custom volume pricing and support terms.

Track Cost in Your Code

Each successful response consumes a fixed number of credits, so cost per document is predictable.

Prerequisite: Python 3.9+, `pip install requests`, and a STRUCTOCR_API_KEY

import base64
import os
import requests

with open("invoice.jpg", "rb") as image_file:
    image = base64.b64encode(image_file.read()).decode("ascii")

response = requests.post(
    "https://api.structocr.com/v1/invoice",
    headers={"x-api-key": os.environ["STRUCTOCR_API_KEY"]},
    json={"img": image},
    timeout=30,
)
response.raise_for_status()
data = response.json()["data"]
print("invoice_number:", data.get("invoice_number"))
print("date:", data.get("date"))
print("due_date:", data.get("due_date"))
print("currency:", data.get("currency"))

Billable Response

Only a successful response like this consumes credits. Field values are illustrative.

{
  "success": true,
  "data": {
    "invoice_number": "…",
    "date": "…",
    "due_date": "…",
    "currency": "…"
  }
}
