Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/sentences/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost ($0.03 USDC) extraction of the top 10 most important sentences from a single text block up to 50,000 characters. Ideal for agents that need quick sentence-level summarization without full abstractive summarization. Prefer this over full summarization APIs when you want to preserve original wording and just need ranking/selection rather than paraphrasing.
Side effects
- Text exceeds 50000 character limit — request rejected or truncated
- Empty or whitespace-only text input — may return empty results or error
- Payment not attached or insufficient USDC via x402 — 402 Payment Required response
- Text with no clear sentence boundaries — may produce unexpected segmentation results
- Network timeout on very large inputs near the character limit
