# Flickr Commons Institutions API

The public list of Commons institutions, with their links and launch dates.

`GET /v1/flickr/commons/institutions` returns `data.institutions`. Each institution carries `id`, `name`, `launchedAt` and `urls` with `site`, `license` and `flickr`. The list is not paged; it is the public Commons institution set returned in one response.

Use it to find the museums, libraries and archives whose public photography is part of Commons, then read their photostreams with the user routes. The list is small and changes rarely.

## FAQ

### What is an institution id?

The institution’s NSID. Use it with GET /v1/flickr/users/{userId} to read the institution’s profile and photostream.

### Does the list page?

No. It is the full public institution list in one response.

### How much does the institutions list cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth.

### Are all Commons institutions included?

The route returns the institution records the public list gives. A missing institution is not invented from a photostream.
