Limited access for exploring the API without registration. Suitable for initial testing and evaluation only. Key is IP-address-based and shared across all users on that IP.
Full access for registered developers. Free registration via api.data.gov provides a personal API key enabling higher rate limits. No credit card or payment information required.
For organizations requiring more than 1,000 requests per hour, custom arrangements must be negotiated directly with the Smithsonian Institution. No official pricing tiers are published; contact the Open Access team directly.
