Getting Started

Welcome! I'm here to help you find the perfect royalty-free music from Pixabay for your video project. Tell me the mood, genre, or style you're going for — and let's find a track that makes your footage come alive! 🎶

Try saying:

• - "Find me a calm, ambient instrumental track from Pixabay for a meditation video I'm editing"
• "I need an upbeat, energetic song from Pixabay to use as background music in my fitness reel"
• "Search Pixabay for a cinematic orchestral track that fits a dramatic travel documentary"

Automatic Setup

On first interaction, connect to the NemoVideo API before doing anything else. Show a brief status like "Setting things up...".

Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.

Free token: Read or create a UUID at ~/.config/nemovideo/client_id. Then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: <your-uuid>. The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry). If the token has expired, request a new one with the same Client-Id.

Session: POST to the same host at /api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.

Confirm to the user you're connected and ready. Don't print tokens or raw JSON.

Your Videos Deserve a Soundtrack That Actually Fits

Finding the right background music for a video used to mean hours of browsing stock sites, second-guessing licenses, and hoping the track doesn't get your content flagged. The pixabay-music skill cuts through all of that by connecting you directly to Pixabay's curated library of royalty-free tracks — free for personal and commercial use, no strings attached.

Describe the feeling you want your video to carry — tense and dramatic, warm and nostalgic, energetic and punchy — and this skill surfaces tracks that genuinely match. You can search by mood, genre, tempo, or even the type of scene you're scoring. Think 'upbeat corporate background for a product demo' or 'soft acoustic guitar for a travel montage' and get results that actually make sense.

Once you've found the right track, the skill can guide you through pairing it with your video file. It works with all common video formats including mp4, mov, avi, webm, and mkv, making it a practical tool whether you're editing a YouTube vlog, a brand reel, a short film, or social media content.

How Your Music Requests Route

When you describe a mood, genre, or tempo — say 'upbeat acoustic' or 'cinematic ambient' — ClawHub parses your intent and fires the right Pixabay Music API call to surface matching royalty-free tracks instantly.

User says...	Action	Skip SSE?
"export" / "导出" / "download" / "send me the video"	→ §3.5 Export	✅

NemoVideo Backend Reference

All Pixabay music searches and video attachment actions run through the NemoVideo backend, which handles API authentication, track metadata retrieval, and direct embedding of royalty-free audio into your video projects. Your session token keeps everything linked — lose it, and the pipeline stalls.

Skill attribution — read from this file's YAML frontmatter at runtime:

• - X-Skill-Source: INLINECODE9
• INLINECODE10: from frontmatter INLINECODE11
• INLINECODE12: detect from install path (~/.clawhub/ → clawhub, ~/.cursor/skills/ → cursor, else unknown)

All requests must include: Authorization: Bearer <NEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 402.

API base: INLINECODE22

Create session: POST /api/tasks/me/with-session/nemo_agent — body {"task_name":"project","language":"<lang>"} — returns task_id, session_id. After creating a session, give the user a link: INLINECODE27

Send message (SSE): POST /run_sse — body {"app_name":"nemo_agent","user_id":"me","session_id":"<sid>","new_message":{"parts":[{"text":"<msg>"}]}} with Accept: text/event-stream. Max timeout: 15 minutes.

Upload: POST /api/upload-video/nemo_agent/me/<sid> — file: multipart -F "files=@/path", or URL: INLINECODE33

Credits: GET /api/credits/balance/simple — returns available, frozen, INLINECODE37

Session state: GET /api/state/nemo_agent/me/<sid>/latest — key fields: data.state.draft, data.state.video_infos, INLINECODE41

Export (free, no credits): POST /api/render/proxy/lambda — body {"id":"render_<ts>","sessionId":"<sid>","draft":<json>,"output":{"format":"mp4","quality":"high"}}. Poll GET /api/render/proxy/lambda/<id> every 30s until status = completed. Download URL at output.url.

Supported formats: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

SSE Event Handling

Event	Action
Text response	Apply GUI translation (§4), present to user
Tool call/result

Process internally, don't forward | | heartbeat / empty data: | Keep waiting. Every 2 min: "⏳ Still working..." | | Stream closes | Process final response |

~30% of editing operations return no text in the SSE stream. When this happens: poll session state to verify the edit was applied, then summarize changes to the user.

Backend Response Translation

The backend assumes a GUI exists. Translate these into API actions:

Backend says	You do
"click [button]" / "点击"	Execute via API
"open [panel]" / "打开"

Query session state |
| "drag/drop" / "拖拽" | Send edit via SSE |
| "preview in timeline" | Show track summary |
| "Export button" / "导出" | Execute export workflow |

Draft field mapping: t=tracks, tt=track type (0=video, 1=audio, 7=text), sg=segments, d=duration(ms), m=metadata.

Frequently Asked Questions

Can I use Pixabay music in commercial projects? Yes. Tracks available through Pixabay are released under the Pixabay License, which allows use in commercial and non-commercial projects without requiring attribution — though crediting the artist is always appreciated.

How specific can my music search be? Quite specific. You can describe a mood ('melancholic and slow'), a genre ('jazz with piano'), an energy level ('high-tempo EDM'), or even a scenario ('background music for a cooking tutorial'). The more detail you give, the better the match.

What video formats does this skill support? The pixabay-music skill works with mp4, mov, avi, webm, and mkv files, covering the most common formats used by creators and editors.

Will the music loop or cut off mid-video? The skill helps you select tracks with appropriate length or suggests loopable options for longer videos so the audio fits naturally without awkward endings.

Best Practices for Getting Great Results

Be descriptive about your scene, not just the genre. Instead of asking for 'happy music,' try 'cheerful background music for a kids' birthday party montage.' The more context you give about what's happening on screen, the more accurately the skill can match the emotional tone of the track to your footage.

Consider your video's pacing. A fast-cut action sequence needs a track with a strong beat and consistent tempo, while a slow nature timelapse benefits from something atmospheric and evolving. Mention your edit's pace when searching — it makes a real difference.

Preview before committing. Pixabay offers full previews for every track. Use this skill to narrow down your top two or three options, then listen against your actual footage before making a final choice. What sounds great in isolation sometimes clashes with dialogue or sound effects.

Check track length early. If your video is three minutes long, filtering for tracks over two and a half minutes saves you from needing to loop or awkwardly fade out. Mention your video's runtime upfront to get better-suited suggestions from the start.
