Particle API gives you what’s inside the audio. Every episode is transcribed and diarized, broken into structural segments, distilled into engagement-scored clips, and linked to a knowledge graph of people, organizations, and companies. The same identifiers connect a guest on one podcast to a company’s full profile, its product hierarchy, and the sponsors funding the shows where it’s discussed. Use it to track what people are saying, find the most quotable moments on any subject, monitor how companies show up across audio, or build research tools that read audio the way they read text.Documentation Index
