Response fields

Field	Type	Description
domainName	string	The domain as submitted
sld	string	Second-level domain extracted from the input
matches	array	All brands matched. Empty = clean domain.
matches[].brand	string	Canonical brand name
matches[].category	string	FINANCIAL, CRYPTO, PHISHING_HIGH, etc.
matches[].subCategory	string	Business type: BANK, EXCHANGE, WALLET, PAYMENT, etc.

matches[].keyword	string	The keyword that triggered the match
matches[].matchType	string	exact, homoglyph, or levenshtein
blocked	boolean	true if any match has blocking: true

Match types

exact — the SLD contains a keyword verbatim.

Code
paypal-login.com     →  "paypal-login" contains "paypal"
coinbase7842.cfd     →  "coinbase7842" contains "coinbase"

homoglyph — confusable characters normalized to ASCII before matching.

Character	Looks like	Unicode
а (Cyrillic)	a (Latin)	U+0430
е (Cyrillic)	e (Latin)	U+0435
о (Cyrillic)	o (Latin)	U+043E
0 (zero)	o	—
1 (one)	l	—

Code
pаypal.com    →  normalized to "paypal"  →  match
g00gle.com    →  normalized to "google"  →  match

levenshtein — fuzzy edit-distance for typosquatting. Requires keyword 6+ chars, SLD length within ±3 of keyword.

Code
paypall.com   →  distance 1 from "paypal"   →  match
gooogle.com   →  distance 1 from "google"   →  match

Typical integration

Pre-registration screening

Code
RESULT=$(curl -s -X POST https://api.most.ac/v1/trademarks/check \
  -H "Authorization: Bearer bk_..." \
  -H "Content-Type: application/json" \
  -d '{"names": ["example-domain.com"]}')

BLOCKED=$(echo "$RESULT" | jq '.data.results[0].blocked')

if [ "$BLOCKED" = "true" ]; then
  echo "Domain blocked — trademark match detected"
  echo "$RESULT" | jq '.data.results[0].matches'
else
  echo "Domain is clean — proceed with registration"
fi

Batch screening before orders

Check all domains in a batch before submitting to POST /v1/orders:

Code
curl -X POST https://api.most.ac/v1/trademarks/check \
  -H "Authorization: Bearer bk_..." \
  -H "Content-Type: application/json" \
  -d '{
    "names": [
      "client-website.com",
      "new-store-name.net",
      "totally-legit-bank.io",
      "my-brand.dev"
    ]
  }'

Reject or flag any result with "blocked": true before registration.
