is there some API or other mechanism that allows me to create a contact form on my site and have the messages delivered to my mastodon inbox?

You would need to implement your own library/service to create a fediverse instance on your server that will send activitypub stuff to mastodon.
Or use a CLI client on server-side that connects to an existing instance and sends the message from there.
