All of it is made or none of it is. Needs a live key over the whole account; a test key gets 403, and `key.test` mints a test key for the pod instead. `key.access` is required; until 26 November 2026 leaving it out still works, with a `warnings` entry, and then it is a 400.\n\n**The token is shown once.** Send an `Idempotency-Key`: a retry with it returns the same pod, address and key, with `token: null`, because the secret is never stored. If the first answer was lost, rotate the key (`POST /api-keys/{id}/rotate`) for a new secret.",

Without `after`, it first looks back 2 minutes and returns the newest matching message from then, because a code often lands before the call is made; narrow it with `from`, `subject_contains` or `has_code` so an earlier email is not taken for the one you want, or pass `after=now` to wait only for new mail. With `after=now`, `has_code=true` and a `timeout` above 5, it also takes a code that arrived up to 60 seconds before the call and that no key has read, and says so with `looked_back: true`: a code that beat the wait is not lost. Pass the returned `cursor` as `after` on the next call so nothing arriving between calls is missed. Answers 200 with `message: null` and `timed_out: true` when nothing came.

Authentication, filtering by `type` and `identity_id`, and the `after` cursor are all exactly as on `GET /events` — this is that read, held open.\n\n**Reconnection is automatic and lossless.** A compliant client resends the last `id:` it saw as `Last-Event-ID`, which is preferred over `after`, so a dropped connection resumes with no gap and no repeat. The connection closes itself after about 280 seconds so that the last thing you receive is a cursor rather than a socket error; reconnect and carry on.\n\n**It polls, every two seconds, on our side of the wire.** No push exists in the database. What this buys is one held connection instead of a request from your network on a timer, and being woken only when something happened.",
