INPUT — request schema

property	type	description	req?
text	string	Max 10000 chars.	required

OUTPUT — response shape

field	type	description
text	string	Original input string that was scanned for homoglyphs and invisible characters.
text_length	number	Character count of the input string.
homoglyph_findings	array	Array of detected lookalike characters with position, script (Cyrillic/Greek/etc), and ASCII equivalent.
homoglyph_count	number	Total number of homoglyph characters found in the input.
invisible_findings	array	Array of zero-width, invisible, or RTL-override characters detected, with positions and codepoints.
invisible_count	number	Total number of invisible or zero-width characters found.
block_counts	object	Map of Unicode block names to character counts (e.g. Latin, Cyrillic, Greek).
has_mixed_scripts	boolean	True if the input mixes multiple writing scripts, a common phishing signal.
ascii_only	boolean	True if every character is plain ASCII with no Unicode lookalikes possible.
normalized	string	ASCII-folded form of the input with homoglyphs mapped back to their Latin equivalents.
is_suspicious	boolean	True if the input shows signs of a homoglyph or invisible-character attack.
risk_score	number	Phishing risk score from 0 (safe) to 100 (highly suspicious) based on findings.
risk_level	string	Categorical risk bucket such as low, medium, high, or critical.

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.agentutility.ai/homoglyph-check \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# MCP packages on npm under
# @agentutility/mcp-*  (one per cluster)
#
# Catalog + install:
# https://mcp.agentutility.ai
#
# Or call homoglyph-check directly over HTTP — see above.

MCP server handles payment automatically — your coding agent just calls the tool by name.
