Upload a file into a Run
Upload one durable Space File (at path, default uploads/<filename>) and bind it to this Run. The Run’s cell keeps a copy at the returned runtimePath; binding.state reports when it is ready.
Authentication
AuthorizationBearer
Use Bearer <api-key>.
Path parameters
runId
Unique run identifier generated by BCTRL.
Headers
BCTRL-Version
Dated API version. Defaults to the release pinned when the API key was created.
Allowed values:
BCTRL-Space
Select one authorized Space by its opaque ID or unique name. Omission uses the operation default.
BCTRL-Subaccount-Id
Optional effective subaccount context for organization API keys. Subaccount API keys are already scoped and cannot use this header to act as another subaccount.
Idempotency-Key
Optional retry key for this billable operation. Reusing the same key with the same request replays its stable outcome; credential-bearing results may be freshly issued for the same principal. Reusing it with a different request returns 409.
