What this server can do
8 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
flat_auth(action, api_key, password, username)- Authenticate an existing FlatID user. Actions: password (login with username + password → returns API key with full permissions), token (verify an existing API key is valid). Returns scopes and account info on success. Required: action.

Poster posts a request with cash amount, GPS coordinates, token type (FLAT or SAVE), and premium %. System locks tokens in escrow at oracle price × (1 + premium%).

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
