## Other responses

- `202`: Write accepted or dispatched. Poll Location after Retry-After. Send no other write until it ends. X's 408, 500, 502, 503 or 504 after the send gives x_write_ambiguous.
- `400`: The write request is invalid. Xquik dispatched no action.
- `401`: Unauthenticated
- `402`: Payment required. MPP reads include `WWW-Authenticate`. Authenticated reads include balances, plus checkout when the key can open it. A key that reads only gets the account page instead. A failed request never creates checkout. A caller on a plan gets top-up only, plus `credits_renew_at` when the plan renews. Guest keys offer top-up.
- `403`: The connected X account needs reauthentication or is restricted (locked, suspended, or recovering). The error code is `account_needs_reauth` or `account_restricted`.
- `404`: Connected X account not found
- `409`: The idempotency key belongs to a different write request.
- `413`: The media is over Xquik's or X's size limit.
- `415`: The file isn't a supported, readable image or video.
- `422`: X rejected the write or download. Error.code says why. `x_automation_refused` needs no wait. `x_reply_not_allowed` repeats X's refusal of a reply for 1 hour, 4 hours after X refuses it again & 24 hours after each later refusal, with `Retry-After`. Media can fail on its URL, size, origin or timeout. A video too big for X to take in time gets `x_video_too_large`, & its message names a size that works. A post into a Community gets `x_community_not_joined` when the account isn't a member, `x_community_not_selectable` when X's composer can't pick it, & `x_community_post_removed` or `x_community_post_public` when X put it outside the Community. Xquik charges nothing for any of them.
- `429`: The write hit an Xquik limit or X's `x_rate_limited`. Follow `Retry-After` when present. Otherwise back off before retrying. The follow limit's `Retry-After` is the wait until it frees, up to 24 hours.
- `500`: Write failed. Check error, safeToRetry & nextAction. x_write_failed means Xquik can't explain it.
- `503`: Tracking or the write service is down. X's 408, 500, 502, 503 or 504 before the send gives x_transient_error. Check safeToRetry.
- `default`: Unexpected error.
