Apache Superset vs Pick an Agency

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.

Pick an Agency runs a free, no-signup REST + MCP API over its directory of 47,000+ verified marketing agencies, publishing a machine-readable OpenAPI spec at `/api/v1/openapi.json` alongside `/search`, `/agencies/{slug}`, and `/match` endpoints for shortlisting agencies by service, location, and rating. An OPTIONS preflight against `/api/v1/search` confirms the advertised open CORS policy (`access-control-allow-origin: *`), and no endpoint ever demanded a key or returned an auth challenge, reconfirming the stored 'None' auth. The three data-fetching GET endpoints themselves consistently timed out from this sandbox's egress on every attempt — the spec and homepage load fine, so their live JSON payloads could not be directly confirmed this run, though nothing points to the API being down.
