EGRUL is the official Russian registry of legal entities and individual entrepreneurs. I built a service that hosts the entire database — over 22 million records — with full-text search, a visual query builder, API access, and scheduled data exports via webhooks.
The query builder
The killer feature is the query constructor. You build filters visually: pick a field (OKVED code, entity type, status, city), choose an operator (equals, contains, like), set a value, and stack as many conditions as you want with AND/OR logic. Hit "Execute query" and get a table of matching companies. It's basically a no-code interface for writing SQL against the EGRUL database.
Scheduled exports
Found a useful query? Save it and schedule automatic delivery. The planner lets you pick a saved query, set the action (send CSV to email), choose the time and days of the week. Every Monday at noon, you get a fresh list of, say, all active construction companies in Moscow. Sales teams loved this.
Pricing and API
The platform runs on a tiered pricing model. Each tier defines monthly and daily limits for simple and complex queries, and whether webhooks are allowed. There's also a raw API for developers who want to integrate EGRUL data directly into their own systems.
We kept the database in sync with the official Federal Tax Service source, updating it regularly. At peak, we had hundreds of active users — mostly B2B sales teams, legal firms, and fintech companies doing due diligence.
