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: `valid` (boolean indicating if the number is a valid Iranian landline), `normalized` (standardized 11-digit format starting with 0), `areaCode` (e.g. '021' for Tehran), and `city` (the Persian/Farsi city name associated with the area code, e.g. 'تهران').

Example use cases

User registration form phone validation

“A new user entered '02112345678' as their phone number on our Iranian e-commerce site — can you confirm it's a valid landline number and which city it's from?”

Customer data cleanup for Iranian contacts

“I have this Iranian phone number '04433221100' in my database — validate it and tell me if it's a real landline and what area code and city it maps to.”

Fraud detection on Iranian phone submissions

“Someone submitted the phone number '09121234567' as a landline for an Iranian address — validate it as a landline and tell me if it checks out or looks suspicious.”

When to prefer

Choose this endpoint when you need to validate Iranian landline phone numbers specifically — it provides richer output than a simple format check by also returning the normalized form, area code, and associated Iranian city. Prefer it over generic phone validators when working with Persian-language or Iran-focused applications where city identification matters.

Side effects

Missing or empty `value` query parameter returns an error
Non-landline numbers (e.g. mobile numbers starting with 09) may return valid:false
Malformed or non-Iranian numbers return valid:false
Numbers with unsupported area codes may not resolve a city even if structurally valid
Payment failure via x402 results in 402 response before validation occurs
