Example use cases
Deduplicating Persian product listings
“I have two Farsi product descriptions and I want to know how similar they are so I can decide if they're duplicates — compare 'گوشی موبایل سامسونگ گلکسی A53' and 'سامسونگ گلکسی A53 موبایل'.”
Persian FAQ matching
“Check how similar this user's question in Farsi is to our FAQ entry — compare 'چگونه رمز عبور خود را تغییر دهم؟' with 'تغییر رمز عبور چگونه انجام میشود؟' so I know if it's a match.”
Persian plagiarism detection
“Compare these two Persian paragraphs for similarity and tell me how close they are — 'ایران کشوری با تاریخ و فرهنگ غنی است' versus 'ایران دارای فرهنگ و تاریخ بسیار غنی میباشد'.”
Technical details
Endpoint
POSThttps://irantools.johnaio281.workers.dev/api/iran/persian_similarity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare two Persian/Farsi text strings for similarity, especially within an Iranian-language context where Persian-aware normalization and script handling are important. Prefer this over generic string distance libraries when the text may contain Persian-specific characters, diacritics, or Unicode homoglyphs that need proper normalization before comparison.
Side effects
- Missing required field 'a' or 'b' returns a validation error
- Empty strings may return a default or zero similarity score
- Non-Persian (non-Farsi) input may still be processed but results may be less meaningful
- Payment failure (insufficient USDC balance) returns HTTP 402
- Extremely long strings may cause latency or be rejected
