What's the meaning of this? I use base64 to access

OCR.space Free OCR API

HTTP Error <ClientResponse(https://api.ocr.space/parse/image) [403 Forbidden]>\n<CIMultiDictProxy('Cache-Control': 'no-cache', 'Pragma': 'no-cache', 'Content-Type': 'application/json; charset=utf-8', 'Expires': '-1', 'Server': 'Microsoft-IIS/10.0', 'X-AspNet-Version': '4.0.30319', 'X-Powered-By': 'ASP.NET', 'Date': 'Sun, 15 Jun 2025 05:43:04 GMT', 'Content-Length': '87')>\n

Is the request frequency too high? But it didn’t prompt

I tested the issue here, but can not recreate it.
=>If you test the connection with Postman, do you get the same result?

You probably know it, but just in case: Postman is a free Chrome app, see Free OCR API

If you see the problem even with Postman, a screenshot of the result could be helpful.
