# Corporate suppliers ranked by PLACSP award procedures

`GET /api/v1/contracts/top-companies`

Compatibility alias of `/api/v1/tenders/suppliers`. Reads only `placsp_public_company_summary`, ranks corporate suppliers by award-procedure count and never publishes a monetary ranking or rollup. Natural persons are excluded. `province` and `cnae` are rejected until dedicated offline projections exist.
