# Snapshot a machine

`POST /v1/machines/{machine_id}/snapshot`

Managed machines only. External machines return 400 UNSUPPORTED_MACHINE_KIND because Coasty does not own their disks. For managed machines, captures a restorable image and requires `snapshots:write`. The configured one-time fee is charged before dispatch. A conclusive pre-creation rejection is refunded; a timeout, 5xx, or malformed post-dispatch result may already have created the image and returns terminal 503 SNAPSHOT_OUTCOME_UNKNOWN without a blind refund/re-execution.

## Headers

- `Idempotency-Key` string

## Response `200`

Snapshot created.

## Other responses

- `400` — Invalid request body or parameters.
- `401` — Missing, invalid, or revoked API key. Pass `X-API-Key: sk-coasty-live-...` (or test).
- `402` — Insufficient balance for this operation. Direct metered API calls and managed-machine runtime use the prepaid Developer API wallet; scheduled execution is the documented consumer subscription-credit exception. Follow the operation's billing fields and top up the matching balance in the dashboard.
- `403` — API key lacks the required scope or tier-feature is unavailable on the caller's plan.
- `404` — Resource not found in this key's namespace.
- `409` — The resource state conflicts with this operation.
- `413` — The request body exceeds the endpoint limit.
- `422` — The JSON shape is valid but one or more values violate the endpoint contract.
- `429` — Rate or concurrency limit exceeded.
- `500` — Unexpected server error. Retry with exponential backoff.
- `502` — An upstream dependency returned an invalid response.
- `503` — A required service is temporarily unavailable.
- `504` — An upstream dependency timed out.
