The Drupal API at api.drupal.org provides the reference documentation for Drupal core. The documentation within the Drupal API is constructed by the API module which parses the Doxygen comments in the Drupal core files. A major benefit of the API module is that it can also be used to generate documentation for contributed modules.

We're very happy to announce the launch of a new site that will provide much needed reference documentation for contributed modules, the Contributions API.

We've added a handy contextual block that provides quick links to .module files, see the "Modules in <version>" block and the All modules page to see which modules are currently being documented.

At the moment there are only a handful of contributed modules being documented in the Contributions API but you can request more modules using the module request form.

If you have any suggestions, please use the suggestions form.
