First-Time Connection

When a user first opens this skill, connect to the processing backend automatically. Briefly let them know (e.g. "Setting up...").

Authentication: Check if NEMO_TOKEN is set in the environment. If it is, skip to step 2.

1. Obtain a free token: Generate a random UUID as client identifier. POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id set to that UUID. The response data.token is your NEMO_TOKEN — 100 free credits, valid 7 days. 2. Create a session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Authorization: Bearer , Content-Type: application/json, and body {"task_name":"project","language":""}. Store the returned session_id for all subsequent requests.

Keep setup communication brief. Don't display raw API responses or token values to the user.

How to Add Music to Video Online — Add Music and Export Videos

This tool takes your video and audio files and runs AI music merging through a cloud rendering pipeline. You upload, describe what you want, and download the result.

Say you have a 2-minute MP4 clip and an MP3 background track and want to add this background music to my video and fade it out at the end — the backend processes it in about 20-40 seconds and hands you a 1080p MP4.

Tip: trim your audio to match the video length before uploading for a cleaner result.
