Search: GET https://memes.md/api/sounds?q= Optional filters: category, mood, energy (low|medium|high), kind (sfx|voice|music|mixed), maxDuration (seconds), limit (default 20, max 100), offset. Example: https://memes.md/api/sounds?q=fail&mood=funny&maxDuration=3 2. Pick the result whose "whenToUse" matches the moment in the video, and skip any whose "avoidWhen" applies. 3. Download the MP3 from its "url" field and place it in the edit. 4. Use "loudnessLufs" to level it: most sounds need a gain change to sit around -14 LUFS next to dialogue.
