Normalizing “JSC” in your data

When matching or deduplicating company records, the legal suffix is noise — “Acme JSC” and “Acme” should resolve to the same entity. One API call strips it and returns a stable canonical form:

curl -X POST https://api.ambect.com/v1/normalize/company \
  -H "Authorization: Bearer $AMBECT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "Acme JSC", "country": "ae"}'
