For AI agents: The documentation index is at https://docs.digitalocean.com/llms.txt. Markdown versions of pages use the same URL with index.html.md in place of the HTML page (for example, append index.html.md to the directory path instead of opening the HTML document).

Description

Uploads the raw JSONL bytes to the presigned upload_url returned by POST /v1/batches/files.

The URL is dynamic — do not construct it. Use the upload_url value from the previous step verbatim. Its host, path, and query parameters are part of the short-lived (~15 minute) signature and change per request; the server and path shown here are illustrative. If the URL expires before the upload completes, create a new file intent and retry.

POST /v1/batches performs a HEAD check on the uploaded object and will reject the batch if this upload has not completed.
