Hello!
Thank you very much for your hard work—it is highly appreciated.
I am using your product via the API and have the following question:
There is a type of image where text recognition works very well in the Opera/Chrome browser extension. However, recognition through the API is quite poor. Could you please let me know what I might be doing wrong?
In general, if the text is simple, it is recognized well, but more complex texts are recognized poorly, even though the browser extension handles them correctly.
I am attaching links to the images and code:
# --- OCR Function (Your Working Code) ---
def ocr_space_file(filename, overlay=False, api_key='11111111111111111', language='eng'):
""" OCR.space API request with a local file.
:param filename: Your file path & name.
:param overlay: Is OCR.space overlay required in your response.
Defaults to False.
:param api_key: OCR.space API key.
Defaults to 'helloworld'.
:param language: Language code to be used in OCR.
Defaults to 'eng'.
:return: Result in JSON format.
"""
payload = {
'isOverlayRequired': overlay,
'apikey': api_key,
'language': language,
}
try:
with open(filename, 'rb') as f:
r = requests.post(
'https://api.ocr.space/parse/image',
files={'file': f},
data=payload,
proxies=None # Disable proxies for OCR
)
# Check response status
if r.status_code != 200:
print(f"Error: Unable to connect to OCR.space API. Status code: {r.status_code}")
return None
# Parse JSON response
result = r.json()
return result
except requests.exceptions.RequestException as e:
print(f"Error while making a request to OCR.space API: {e}")
return None
except ValueError as e:
print(f"Error parsing JSON response: {e}")
print(r.text) # Output response for debugging
return None
# --- Function to Save Text to File ---
def save_text_to_file(text, file_path):
"""Saves text to a file."""
with open(file_path, 'w', encoding='utf-8') as f:
f.write(text)
What am I doing wrong? 
Hi,
Your screenshot is from Copyfish. This extension uses scale=true and ocrengine=2 as the default settings.
So two suggestions for your API call:
(1) Use scale = true
'scale': "true",
(2) And maybe also use OcrEngine 2:
'ocrengine': "2",
These parameters worked for me.
payload = {
'isOverlayRequired': overlay,
'apikey': api_key,
'language': language,
'scale': "true",
'ocrengine': "2"
}
Thanks it worked for me, now it recognizes more complex texts. Good luck to you.

Hi! Could you please tell me if your API has stopped working? My OCR text recognition via API has not been working since yesterday.
Check the error code

PS C:\Users\abushaev>
The free OCR API was overloaded this morning. Sorry about that. The issue has been fixed now.
The PRO/PRO PDF endpoints were not affected, as they run on different servers.

Everything is working now. Thank you! Where can I learn more about the paid version? I only use text recognition from images, exactly five images per day. I just need it to work smoothly without any overloads.
