How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a structured JSON object containing the input text segmented into an array of individual sentences, enabling downstream per-sentence processing, analysis, or display.
Example use cases
Preprocessing article for NLP pipeline
“I have this 2000-word news article and I need it broken into individual sentences so I can run sentiment analysis on each one — can you split it up for me?”
Counting sentences in legal document
“Take this contract clause and split it into its individual sentences so I can see exactly how many statements it contains: 'The licensee agrees to all terms herein. Violations will result in termination. All disputes shall be settled by arbitration.'”
Chunking text for summarization agent
“Break this long research abstract into separate sentences so I can process each one individually: 'Machine learning has transformed data science. Models now outperform humans on many benchmarks. However, interpretability remains a major challenge. Researchers are actively developing explainability tools.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/sentences/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, low-cost sentence-level tokenization of text up to 50000 characters within an autonomous agent workflow that already supports x402 micropayments on Base. Ideal for preprocessing steps in NLP pipelines where per-call cost efficiency matters and no heavy NLP library is available in the agent runtime.
Side effects
- Text exceeds 50000 character limit — request rejected or truncated
- Empty text input returns empty sentence array or error
- Ambiguous sentence boundaries (abbreviations, ellipses) may cause mis-splits
- Payment failure via x402 if USDC balance is insufficient
- Malformed JSON request body returns 4xx error
