API
A crypto API on a node you run
Everything an arcade does is available by program, with keys its operator gives out. Build a website, a bot or a dashboard on 
Dogecoin, 
Pepecoin, 
Litecoin and 
DigiByte without a third-party API.
Two kinds of key
Your site's back end
Does whatever the operator can, narrowed if you like to chosen modules, read-only, an end date, or certain addresses.
An account's own
Acts exactly as that account would signed in, never as the operator. A way for people to try what an arcade can do.
Every route, by module
The arcade lists every route it serves, grouped by module, and any console command runs in one call.
curl -H "Authorization: Bearer ak_…" https://your-arcade.example/api/v1/whoami
Keys are shown once and kept only as hashes; switching one off takes effect on the next call. Using the ARCADE API, with worked examples (PDF) · Build with us
Questions
Is there a self-hosted Dogecoin API?
Yes. An arcade you run is your own API for Dogecoin and the other chains it runs or borrows, with keys you issue.
Can a bot post on the feed or send coins?
An operator key with write access can run console commands such as posting on the feed. Sends from the node's own wallet are confirmed only at the node's machine.
Can users get their own API keys?
If the operator allows it: they choose whether users may make keys, how many each, and how many calls a minute.
