Example use cases
Normalize scraped Iranian news text
“I've scraped some Persian news articles and the text has mixed Arabic and Persian characters all jumbled together — can you normalize this text so it's consistently Persian: 'اين خبر مهم است و بايد خواند'?”
Prepare Farsi content for search indexing
“Before I index these Persian product descriptions into my search engine, I need them normalized so searches work properly. Can you normalize this Farsi text: 'قيمت كالا ٢٠٠٠ تومان است'?”
Clean Persian user input for database storage
“A user submitted this Persian comment but it looks like it has inconsistent characters and encoding issues — please normalize it before I store it: 'دوستان عزيز، سلام و خوش آمديد به سايت ما'”

Endpoint
POSThttps://irantools.johnaio281.workers.dev/api/iran/persian_normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to standardize Persian/Farsi text that may contain mixed Arabic and Persian Unicode code points, inconsistent character encodings, or typography issues before NLP processing, search indexing, or database storage. It is especially useful for text scraped from Iranian websites where character inconsistencies are common. Prefer this over generic Unicode normalization (NFC/NFD) when the text is specifically Persian and requires Iranian typography conventions.

- Empty or missing 'text' field returns a 400 validation error
