How this service works
Persian (Farsi) and Iranian utility API for AI agents. Text normalization, transliteration, Jalali (Solar Hijri) calendar conversion, Persian digits and number-to-words, Iranian national ID / Sheba (IBAN) / mobile / landline / postal code / bank card (Luhn PAN) / company ID / economic code validators, Iranian provinces and cities, official Jalali holidays, Rial-Toman conversion. Also a FIXED-PRICE deliverable SKU: Persian/Arabic data cleanup at $0.90, $9 or $25 flat per file (not per call) - upload a CSV, TSV or text file and get it back normalized, with an optional Latin transliteration column. Pay per request in USDC on Base via x402 - no signup, no API key, no KYC.
Output
A JSON object containing a single 'similarity' field with a numeric score (likely 0–1) indicating how similar the two input Farsi strings are, where 1 represents identical or maximum similarity.
Example use cases
Deduplicating Persian content entries
“I have two Farsi product descriptions — 'کفش ورزشی مردانه' and 'کفش مردانه ورزشی' — can you check how similar they are so I can tell if they're duplicates?”
Fuzzy matching Persian user inputs
“A user typed 'تهران' and another typed 'طهران' — how similar are those two Farsi strings? I need a score to decide if they mean the same city.”
Evaluating Persian translation quality
“I translated the same sentence into Farsi twice using different methods: 'من به مدرسه میروم' and 'من به مدرسه رفتم' — how similar are these two Persian strings?”

Endpoint
GEThttps://farsi-tools.johnaio281.workers.dev/api/fa/similarity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare two Persian (Farsi) strings specifically, especially in a pay-per-call context without needing a subscription. Ideal for lightweight, single-pair comparisons of Persian text where a dedicated Farsi-aware similarity metric is preferred over generic multilingual embeddings.
Side effects
- Missing required query parameters 'a' or 'b' returns an error
- Non-Persian or empty strings may return low or unexpected similarity scores
- Payment failure via x402 protocol returns 402 Payment Required
- Very long strings may cause latency or truncation issues
