Microfiber is an generic adapter for making HTTP requests to an arbitrary JSON loving REST API like CouchDB. This means the Microfiber API *is* the CouchDB REST API (plus a few carefully chosen convenience wrappers).

Microfiber has internal support for OAuth 1.0a and basic HTTP auth. Microfiber also has comprehensive SSL support, including support for client certificates.
