}Request a presigned upload URL for a custom node package
Returns a presigned S3 PUT URL for uploading a custom node zip archive. After uploading, call POST /nodes to register the node metadata.
Accepts JWT or dk-. The returned URL is a single-part PUT — fine for
files up to the server’s configured request cap (default 500 MB; S3’s
hard ceiling on a single PUT is 5 GB). Larger archives require the
JWT-only multipart flow under /uploads/multipart/*.

}Authorizations
User session JWT (Bearer ). Must be paired with the X-Team-ID
request header on team-scoped endpoints so the server knows which
team's resources to operate on.
Headers
UUID of the team to scope the request to. Used by dual-auth endpoints (runtime + scoped management):
- JWT callers MUST send it — a user may belong to multiple teams and the runtime cannot otherwise know which one to operate on. Missing header → 400.
- Credential callers (
sk-,dk-) can omit it because the team is derived from the credential row itself. Any value sent is ignored.
"019abc12-4567-7890-abcd-ef1234567891"
Body
Request a presigned S3 PUT URL to upload a custom node package.
Original filename of the zip archive.
"ComfyUI-Impact-Pack.zip"
File size in bytes.

1 - 100^[a-zA-Z0-9][a-zA-Z0-9._-]{0,99}$"ComfyUI-Impact-Pack"
Response
Presigned upload URL generated
S3 PUT URL for uploading the node package. Include all upload_headers in the request.
