**APIs profiled:** 3

Formspree is a form backend for static and Jamstack sites. Two API surfaces matter: (1) the public form-submission endpoint (formspree.io/f/{hashid}) that accepts POST submissions and returns JSON when the Accept header is set, and (2) the Forms API (formspree.io/api/0/...) for programmatic submission retrieval, export and form management. Plugins and the Formspree CLI extend the surface.
