Use the result in your application. Keep the receipt as a record of what ran. It does not include the prompt or model output. A successful live run can return a result. Every final run leaves a receipt that does not copy the prompt or output. Echo, failed, cancelled, and expired runs do not return model output.

​
Result

Fetch a result only after a live run reaches completed:
A 404 means the run is not complete, produced no result, or the result expired. When retention_expires_at contains a date, that is the result’s expiry time. If it is null, the API has not reported an automatic expiry. Inspect the model requested and the model reported by the provider:
requested is what Millwork asked for. resolved is what the provider or gateway reported.

​
Receipt

A receipt records what Millwork tried, which option succeeded, which model and provider answered, what the run used, and which limits or checks applied. It does not copy the prompt or output.
The values above are examples. IDs and customer content are intentionally absent.

​
What to store

  • Store the result only as long as your application needs it.
  • Keep the receipt when you need a record without the prompt or model output.
  • Keep the run ID (execution_id) so you can connect status, result, receipt, and support context.

​
Final outcomes

A run can end as completed, failed, cancelled, or expired. Request the result only after completed. For every other final status, read the run, events, and receipt to see what happened. No result? Follow the recovery steps in Errors and retries.
