The api allows the frontend to access the database. Most endpoints are authenticated using NIP 98.
## `class ApiError`
- This is a custom error class with an additional `status` property
## `function makeAuth<T>()`
- If the user is not currently logged in, returns undefined
- Otherwise, builds an NIP 98 auth header with no `method` and `u` set to `VITE_API_URL`. This is non-standard, but intentional in order to prevent repeated signer authorizations.
- This function is memoized over pubkey and expires after 10 minutes.
- Returns the full `Authorization` header value.
