How this service works
Extractive summary of a text - the most representative sentences by word frequency in original order, with scores, compression ratio and top terms
Output
A JSON object containing a short summary string, an array of key sentences each with its score (0–100) and original position in the text, the total number of sentences in the source text, the number selected, a compression ratio, and an array of top terms by frequency.
Example use cases
Research abstract compression
“Here's a 1,200-word academic paper abstract — can you pull out the 4 most representative sentences by word frequency so I can quickly grasp the core findings?”
News article quick digest

Technical details
Endpoint
GEThttps://saylorinnovations.com/api/text/summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, deterministic extractive summarization — selecting actual sentences from the source text rather than generating new ones. Ideal when fidelity to the original wording matters, when you want scored and ranked sentences for further filtering, or when you need compression metrics. Prefer over abstractive summarizers when hallucination risk is unacceptable.
Side effects
- Text shorter than 200 characters or longer than 5000 characters returns a validation error
- Sentences parameter outside 1–10 range returns an error
- Missing required 'text' query parameter returns a 400 bad request
- Non-text or binary content passed as text may produce meaningless output
- Payment not included or rejected returns a 402 Payment Required
