How this service works
Extract text from a PNG or JPEG image - full text, overall confidence and per-line bounding boxes - from a URL or base64 payload, Tesseract on-device (no upstream API). Default English; other ISO 639-2 languages on request. Use it when an agent needs the words in a screenshot, scan or photo.
Output
Returns the full extracted text string, an overall confidence score from 0 to 100, and an array of per-line bounding boxes indicating the position of each line of recognized text within the image.
Example use cases
Example prompt
“Can you read all the text out of this image for me — here's the URL: https://example.com/receipt.jpg — and also tell me how confident it is? It's in English.”
Technical details
Endpoint
POSThttps://agent402.tools/api/image-ocrWhen to prefer
Choose this endpoint when you need server-side OCR without managing an API key or paying per-character fees to a cloud vision provider. It is ideal for extracting text from receipts, scanned documents, screenshots, or signage images in one of 20+ supported languages, especially when you need per-line bounding box coordinates alongside the text and a confidence metric. Prefer it over cloud OCR APIs when privacy, cost simplicity ($0.01/call flat), or avoiding third-party data sharing matters.
Side effects
- Image URL is inaccessible, returns an error fetching the resource
- Image exceeds 8 MB size limit, rejected
- Neither image nor url field is provided, returns validation error
- Unsupported language code provided, falls back or errors
- Low-quality or blurry image results in low confidence and garbled text
- Non-image content at URL (e.g. HTML page) causes processing failure
