Charity Search vs Pick an Agency
CharityAPI (rebranded from OrgHunter) looks up US nonprofits by EIN across basic profile, financial, geolocation, and NTEE-classification datasets, sourced from IRS filings and pitched at donation platforms and vetting tools. Its real backend at `data.orghunter.com` trades a query-string `user_key` for JSON responses and rejects unauthenticated calls with a 403, and offers free development-phase API keys with production usage gated behind paid or affiliate-only plans.
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.
