This directory contains client libraries for the MCIAS REST API.
All language implementations expose this API:
```
Client(server_url, [ca_cert_path], [token])
login(username, password, [totp_code]) → (token, expires_at)
logout() → void
renew_token() → (token, expires_at)
validate_token(token) → {valid, sub, roles, expires_at}
get_public_key() → {kty, crv, x}
health() → void  # raises/errors on 5xx
create_account(username, account_type, [password]) → account
list_accounts() → [account]
get_account(id) → account
update_account(id, [status]) → account
delete_account(id) → void
get_roles(account_id) → [role]
set_roles(account_id, roles) → void
issue_service_token(account_id) → (token, expires_at)
revoke_token(jti) → void
get_pg_creds(account_id) → pg_creds
set_pg_creds(account_id, host, port, database, username, password) → void
```
