What is the AI Summarization API?
The Helix AI Summarization API turns long text, URLs, or documents into concise summaries using state-of-the-art transformer models. Choose extractive (pull key sentences) or abstractive (generate new prose) modes, and get bullet points or paragraphs in seconds.
How it works
- 1POST text, a URL, or both to /summarize — receive a 2-5 sentence summary.
- 2POST to /bullet-points to get a list of key takeaways instead of prose.
- 3POST a URL to /summarize/url and we fetch + parse the page (Readability extraction) before summarizing.
- 4Powered by HuggingFace BART-large-CNN with optional Pegasus for longer documents.
- 5Specify `min_length`, `max_length`, and `style` (formal/casual/technical) to tune output.
Endpoints
3 REST endpoints, all returning consistent JSON.
