What you can do
Apivom Atlas resells the official TOBB² trade-registry web services as a modern REST API. Query companies by tax number at four detail levels — from basic registry identity to the full record with partners, officers, capital and status — plus branch cards by MERSIS number. Responses come from the authoritative MERSIS source, are cached server-side (repeat queries are free), and every query is logged with full request/response payloads in the customer portal.
² TOBB: The Union of Chambers and Commodity Exchanges of Türkiye
Authentication
Per-tenant API key (x-api-key header) issued in the Apivom Atlas portal. Prepaid balance; only data-returning queries are charged.
