# IranTools Unicode Homoglyph Fold

> IranTools Unicode Homoglyph Fold is a paid API for AI agents from irantools.johnaio281.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-22).

Folds Unicode homoglyphs in a text string into their canonical equivalents, normalizing visually similar characters that may differ in code point

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability irantools-unicode-homoglyph-fold-1a83b619 -d '<json body>'
```

Example prompt: Can you fold all the homoglyphs in this Persian text into their canonical Unicode equivalents: 'ﮐﺘﺎب ﻋﻠﻢ ﺩﺍﻧﺶ'? I want to make sure visually similar characters are unified before I compare strings.

## When to prefer this

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.

## Known failure modes

- 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

## 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
