What this API does not read
2026-01-14 · Captchas
reCAPTCHA, hCaptcha, audio prompts, and Devanagari digits are outside the three engines.
Three models ship with the service: text (ocr), arithmetic (math), and Hindi number words (hindi_math). They look at a still image. They do not drive a browser.
Audio captchas are not accepted. There is no audio field. A picture of a speaker icon is not the sound.
Devanagari digits ० through ९ are not read. Hindi captchas that work here write the first operand as a word, such as पच्चीस, and the second as Western digits.
A full-page screenshot is a poor input. It is large, it trips the pixel limit, and the characters are a small part of the frame. Send the captcha image alone.
