What is the Metropolitan Museum of Art API?
The Metropolitan Museum of Art Collection API is a free, key-free API providing access to more than 470,000 artworks, including high-resolution images for public-domain pieces, artist information and complete object metadata.
The Met released its entire collection dataset under open access, and the API reflects that: no key, no quota, and genuinely high-resolution images for anything in the public domain — usable commercially without a licence fee.
The one field to check before using an image is `isPublicDomain`. Objects still in copyright return metadata but no usable image URL, so filter on that boolean rather than assuming every record has a picture you can display.

Common errors and how to fix them
Empty primaryImage
The object is still in copyright.
Fix: Filter on isPublicDomain before rendering; not every record has a usable image.
Search returns IDs only
The search endpoint returns objectIDs, not full records.
Fix: Fetch each object individually — expect an N+1 pattern and cache results.
404
Unknown object ID.
Fix: IDs are not contiguous; many numbers in the range do not exist.
Metropolitan Museum of Art API — frequently asked questions
Is the Met Museum API free?
Yes, completely free with no API key. Public-domain images are released under CC0, so they can be used commercially without a licence fee.
Can I use the images commercially?
Only where isPublicDomain is true — those are CC0. Objects still in copyright return metadata but no usable image URL.
Why does search only return numbers?
The search endpoint returns matching object IDs. You then fetch each object individually, which means an N+1 request pattern — cache aggressively.
How many artworks are available?
Over 470,000 objects spanning 5,000 years, though only a subset have public-domain images attached.
