Get a link to upload a file

Text (html, js, css, json; UTF-8, up to 2,000,000 bytes): pass public_url as a scene's src_url or reference it from scenes with <script src>. AUDIO you rendered yourself (wav, mp3, ogg, m4a, flac; up to 50 MB, counted against the storage quota) goes straight to storage: PUT it to the presigned upload_url with the returned headers (Content-Type is signed), then POST complete_url, which checks the stored bytes' magic number, records the file in the media library and as a music track that is transcoded and tempo/beat-analysed like any other (kind "sfx": library entry only), and returns track_id; the returned curl does both. Then PATCH /projects/{id}/music with trackId (or url: public_url) makes it the project music. Same access as landing authored compositions. Images and video also go straight to storage (see complete_url). Free.

curl -X POST "https://example.com/uploads" \  -H "Content-Type: application/json" \  -d '{    "file_name": "score.wav"  }'
