API features
Image text extraction
Upload an image and extract recognized text lines plus combined text for document intake and automation workflows.
Unlimited OCR usage
Run OCR whenever your workflow needs it under one annual subscription, without per-call charges or a sales-led setup.
Searchable archive support
Store recognized text alongside images so receipts, scans, screenshots, and forms become searchable.
Document intake automation
Route extracted text into approval workflows, ticketing systems, databases, and downstream AI processing.
Batch-friendly API design
Call the endpoint repeatedly from backend jobs when processing incoming image files or historical document queues.
Standalone OCR interface
Subscribe to the OCR API independently when the workflow only needs image-to-text output.

Image OCR
Read text from an image using a multipart file upload.
Input and coverage: JPEG, PNG, WebP, TIFF, or BMP input, maximum 10 MiB. Recognition quality depends on resolution, contrast, and layout.
Example request
Download the public sample image first. Replace YOUR_APPKEY with your own key before sending the API request.

}Frequently asked questions
Common questions about request limits, trials, renewal, and cancellation.
What does the 5 requests per second limit mean?
It is a request-rate limit, not a concurrency allowance. Keep your request rate at or below 5 per second. If the service returns a rate-limit response, reduce the frequency and retry with backoff.
Is total paid usage limited?
There is no total request cap during an active paid subscription and no usage-based overage charge.
How does the free trial work?
Each account can receive a limited trial key. Requests are shared across APIs in the same category. Check Trial Keys for the exact allowance and remaining requests.
How do renewal and cancellation work?
The plan renews annually until canceled. Manage or cancel the renewal from Dashboard → Orders & Billing. Access continues through the paid period after cancellation. See the Terms of Service for the current refund policy. If the billing portal is unavailable, contact support.
