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 'gregorian' field with the converted date formatted as YYYY-MM-DD (e.g. {"gregorian": "2026-10-21"})
Example use cases
Scheduling a meeting with Iranian partners
“Our Iranian counterpart sent us a meeting request for Jalali date 1404, month 4, day 10 — what day is that on the regular calendar?”
Processing Persian-dated legal documents
“I have a contract with a Jalali date of year 1402, month 12, day 25 — can you tell me the corresponding Gregorian date so I can enter it in our system?”
Converting a Persian birthday to Gregorian
“My friend told me their birthday is the 1st of Mordad 1380 in the Iranian calendar — what's that date in the Gregorian calendar? That's year 1380, month 5, day 1 in Jalali.”

Endpoint
GEThttps://farsi-tools.johnaio281.workers.dev/api/fa/jalali-to-gregorian?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically convert Persian (Jalali/Solar Hijri/Shamsi) calendar dates to Gregorian dates, particularly for applications serving Iranian users, processing Persian-dated documents, or integrating with Iranian business systems. It is ideal for pay-per-call usage patterns where you don't want to maintain a calendar library, and when operating in an x402/USDC micropayment environment.
