How this service works
Persian and Iranian utilities for AI agents, plus general text/Unicode tooling. Jalali (Solar Hijri) calendar conversion, Iranian national ID / SHEBA / bank card / postal code / economic code validation, province and city lookup, official public holidays, Persian text normalization, keyword extraction, sentence splitting, similarity, HTML stripping, RTL fixing, Unicode homoglyph folding, script detection, NFC/NFD normalization, grapheme counting, date description, business-day counting, slugify, FNV-1a hashing, Shannon entropy, format and encoding detection, byte sizes. Pay per call in USDC on Base via x402 - no signup, no API key, no KYC. The same tools are also exposed as MCP tools at /mcp.
Output
Returns an object containing the homoglyph-folded version of the input text, where visually similar Unicode characters have been replaced with their canonical equivalents, enabling reliable string comparison and deduplication
Example use cases
Deduplicating user search queries
“I'm getting duplicate search hits because users are typing the same Persian word with different-looking but equivalent Unicode characters — can you fold the homoglyphs in 'كتاب' and 'کتاب' so I can compare them as the same string?”
Preventing homoglyph spoofing in usernames
“Someone registered a username that looks identical to an existing one but uses lookalike Unicode characters — can you run homoglyph folding on the string 'аdmin' to see if it maps to a canonical form I should block?”
Normalizing RTL text before indexing
“Before I index this Arabic-script content in my search engine, I need to fold any homoglyphs so documents with visually identical words aren't treated as different — please canonicalize this text: 'دانشگاه تهران'”
Technical details
Endpoint
POSThttps://irantools.johnaio281.workers.dev/api/iran/homoglyph_fold?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to normalize Unicode text that may contain visually indistinguishable but code-point-distinct characters — especially in Persian, Arabic, or mixed-script contexts — before string matching, indexing, deduplication, or security checks. Prefer it over simple NFC/NFD normalization when the concern is lookalike characters across scripts rather than just canonical decomposition.
Side effects
- Missing 'text' field returns a validation error
- Empty string input may return the input unchanged
- Extremely long strings may hit payload size limits
- Non-UTF-8 encoded input may cause unexpected behavior
- Payment failure via x402 if USDC balance is insufficient
