Apache Superset vs Tomba email finder

Apache Superset is an open-source data-exploration and business-intelligence platform for building interactive dashboards and running ad-hoc SQL over dozens of database engines. Its REST API, documented at superset.apache.org/docs/api (confirmed live, redirecting to a 200 Swagger reference), exposes charts, dashboards, datasets, and database connections under `/api/v1/`, authenticated with a JWT access token obtained by POSTing credentials to `/api/v1/security/login` rather than a long-lived static key. Superset is self-hosted with no single Apache-run public instance, so HTTPS and CORS are configured per deployment rather than fixed by a vendor.

Tomba's Email Finder API discovers and verifies professional email addresses from a company domain or a person's name, and doubles as a B2B prospecting and lead-enrichment tool via linked domain-search and phone-finder endpoints. It authenticates with a paired `X-Tomba-Key`/`X-Tomba-Secret` header set rather than a single token, and a live Origin-header probe confirms it explicitly supports browser CORS, echoing the request Origin with credentials enabled on both a GET and an OPTIONS preflight.
