Pick an Agency vs Redash

Pick an Agency runs a free, no-signup REST + MCP API over its directory of 47,000+ verified marketing agencies. It has `/search`, `/agencies/{slug}`, and `/match` endpoints for shortlisting agencies by service, location, and rating, plus a machine-readable OpenAPI spec at `/api/v1/openapi.json`. A live GET this run against `/search` and against `/match` both returned real agency records with `access-control-allow-origin: *` and no auth challenge. This confirms the stored 'None' auth and open CORS policy with real JSON payloads.

Redash is an open-source query and dashboard tool that lets teams connect to a data source, write a query, and visualize the results without writing frontend code. Its REST API, documented live at redash.io/help/user-guide/integrations-and-api/api, authenticates each request with a per-user API key sent as `Authorization: Key <api_key>` and lets scripts create queries, trigger refreshes, and pull dashboard results as JSON. Redash Inc.'s hosted SaaS at app.redash.io was discontinued in 2021, so the project now ships only as free, self-hosted open-source software with no vendor-run instance to point the API at.
