Soft deadline behavior

This route follows a soft deadline model — it no longer always responds synchronously.
  • If the snapshot finishes within ~90 seconds, the route responds with 200 success and a signed download URL (valid for 30 days), exactly as before.
  • If the snapshot takes longer than ~90 seconds to generate, the route responds immediately with 202 and the code SNAPSHOT_PROCESSING. This is not a failure. The snapshot keeps generating in the background and will appear in the snapshot listing on its own, typically within ~2 minutes. This is expected behavior for large applications.
Do not use this POST endpoint as a polling mechanism. To check whether a SNAPSHOT_PROCESSING snapshot has completed, use the List Snapshots (GET) endpoint — not another POST. Re-posting after the snapshot has finished starts a brand-new snapshot from scratch.
The client should branch on the response as follows:
ResponseMeaningWhat to do
status === "success"Snapshot is ready.Use the url to download it.
status === "error" and code === "SNAPSHOT_PROCESSING"Snapshot is still generating.Wait ~2 minutes, then confirm via List Snapshots (GET). Do not re-POST.
status === "error" with any other codeActual failure.Handle the error (see below).

​
Response

​
status
string
Indicates whether the call was successful.. success if successful, error if not.
​
response
object
The contents of the response. Present only when status is success.
​
SNAPSHOT_PROCESSING
202
Returned when the snapshot exceeds the ~90 second soft deadline. The snapshot is still being generated in the background and will appear in the snapshot listing on its own, typically within ~2 minutes. Not an error — wait and confirm via the GET listing endpoint.

​
Errors

A snapshot request can be rejected with 429 Too Many Requests. Use the code field to tell the two cases apart:
​
KEEP_CALM
429
Short-term cooldown — you hit the per-user (1 request / 5s) or per-application (1 request / 180s) limit. Back off and retry shortly.
​
DAILY_SNAPSHOTS_LIMIT_REACHED
429
Daily quota reached — the account used up its plan’s daily snapshot allowance ((RAM / 256) × 2 per 24h). The quota frees up as the rolling 24-hour window advances; for a higher daily allowance, upgrade the plan.
