Create an asset upload

client.assets.create(, ?): AssetCreateResponse { asset_id, status, uploaded_via, 6 more }

POST/assets

Creates an asset via one of three paths. (1) Direct bytes: send multipart/form-data with a file part (≤4 MB) plus workspace_id — FLORA stores the bytes and returns a ready asset in one call. (2) Server-side fetch: send JSON with source set to any public HTTPS URL (≤50 MB) — FLORA fetches the bytes with SSRF protection (private/loopback/metadata IPs and redirects to them are blocked) and stores them. (3) Signed upload: send JSON with source=“signed-url” to reserve a presigned upload URL for files larger than 4 MB; upload the bytes, then call the complete endpoint. Allowed types: images (jpeg, png, webp, gif, avif, heic, heif), video (mp4, webm, quicktime), audio (mpeg, wav, ogg), and pdf; images are capped at 150 MP. Pass project_id on any path to also surface the asset on that project’s canvas. Mutating public API requests support an optional Idempotency-Key header for client retries; duplicate keys within two hours return idempotency_duplicate.
