Smithsonian Plans Pricing
The Smithsonian Open Access API is free to use for all purposes. API keys are obtained through api.data.gov, the US Government's shared API management platform. There are no paid tiers or commercial licensing fees as all content is released under CC0 (public domain) license.
Smithsonian Plans Pricing is the machine-readable pricing-plan profile for Smithsonian Institution on the APIs.io network, conforming to the API Commons Plans specification.
It defines 3 plans, with named plans including DEMO_KEY (No Registration), Standard API Key, High-Volume Access.
Tagged areas include Museums, Open Access, Cultural Heritage, Collection, and Image.
Plans
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.
