Charlie's simple text storage API

API:
    POST `/store`
        Store a string and retreive its key.

        Parameters (in POST body, as url-encoded):
            text: The string to store

        Returns (plaintext):
            The key that the string can be accessed by

    GET `/<key>`
        Retreive the string stored under a key.

Note:
    Offered as-is, I won't get mad if you use it but please don't overdo it, I
    do have to pay for storage and data usage of this server.

    The strings you store with with this API will be saved in plaintext and
    accessible to theoretically anyone (I can't and won't promise this API is
    well-protected against enumeration attacks or the likes).

    Don't use this API for
    -   confidential or otherwise secret stuff
    -   illegal stuff for either you, me or my hosting provider
    -   rude stuff, including bigotry
    -   stuff that's important to you (deletion at any time for any reason)
    -   stuff that's not within reasonable limits of byte size
