# List API keys

`GET /v1/keys`

Scope: `keys` (always opt-in). Scoped to the CALLING key's mode: a sandbox (sk-coasty-test-*) key sees only sandbox keys, a live key sees live plus legacy. Each item carries `key_kind` so you can tell them apart. A key-store outage returns 503 DB_UNAVAILABLE with Retry-After rather than a bare 500.

## Response `200`

Keys.

- object
  - `keys` APIKeyListItem[]
    - `key_id` string, required
    - `name` string, required
    - `tier` string, required
    - `scopes` string[], required
    - `created_at` string, date-time, required
    - `last_used_at` string, date-time, nullable
    - `key_prefix` string, required — Stored 16-character identification prefix; never the full secret.
    - `key_kind` 'live' | 'test' | 'legacy', nullable — Which prefix family this key belongs to: `live` (sk-coasty-live-*), `test` (sk-coasty-test-*, sandbox, never bills), or `legacy` (minted before the split; behaves as live). The listing is scoped to the CALLING key's own mode, so a sandbox key only ever sees sandbox keys and a live key sees live plus legacy.
