Presign a File Upload

post/v1/graphs/{graph_id}/operations/create-file-upload

Presign an S3 URL for direct upload and register the file. After uploading to the returned URL, call POST /operations/ingest-file to stage it into DuckDB. The staging table is auto-created if missing. Not allowed on entity graphs or shared repositories.

Idempotency: supply an Idempotency-Key header to make safe retries; replays within 24 hours return the same envelope. Reusing the key with a different body returns HTTP 409 Conflict.

Authentication

Authenticate in any one of these ways — not all of them:

API key in the X-API-Key header.
Bearer token in the Authorization header.

Path parameters

Name	Type	Description
`graph_id`required	string	Graph Id

Header parameters

Name	Type	Description
`Idempotency-Key`optional	string	Idempotency-Key

Request body

Required, application/json.

Field	Type	Description
`file_name`required	string	File name to upload
`content_type`optional	string	File MIME type Default: `application/x-parquet`
`table_name`optional	string	Table name to associate file with (required for first-class /files endpoint)
`file_size_bytes`optional	integer	Size of the file about to be uploaded, in bytes. Optional; when supplied, an over-limit file is rejected here instead of after it has been pushed to S3 and rejected by ingest-file. Advisory only — the authoritative check measures the object after upload.

Example request
