# Account & Usage

> Introspect the authenticated key, read the credit balance, and review API usage.

Inspect the authenticated key and your organization's credit position:

* [`GET /me`](/api-reference/account/me) — introspect the key, its organization, and
  the available credit balance. Requires **any** valid key (no specific scope).
* [`GET /credits`](/api-reference/account/credits) — the organization's remaining
  balance, broken into plan and top-up credits. Requires `usage.read`.
* [`GET /usage`](/api-reference/account/usage) — API-attributed credit usage,
  grouped by action or day. Requires `usage.read`.

<Tip>
  `GET /me` is the fastest way to confirm a new key works and to check its scopes and
  expiry before you wire it into an integration. See the [quickstart](/quickstart).
