How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object containing the input text split into an array of individual sentences, segmented at natural sentence boundaries. The exact response shape follows the additionalProperties:true schema, so the agent should expect a structured object with sentence segments.
Example use cases
NLP pipeline sentence chunking
“Break this product review into individual sentences so I can analyze each one separately: 'The battery life is incredible. Setup was a nightmare. Customer support never responded to my emails. Overall I'd recommend it to patient people.'”
Document preprocessing for summarization
“I need to split this 10-paragraph news article into sentence-level chunks before I feed it into my summarizer — can you segment it sentence by sentence?”
Training data preparation
“Take this block of raw text and split it into sentences for me so I can use them as training examples: 'Language models learn from patterns in text. Each sentence carries distinct meaning. Sentence boundaries help segment context effectively.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/sentences/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call sentence tokenizer without standing up your own NLP infrastructure. It's ideal for autonomous agents that occasionally need sentence segmentation as part of a larger pipeline and want to pay only per use ($0.018 USDC) rather than maintain a full NLP service. Prefer it over general-purpose LLM calls when deterministic sentence splitting is needed at low cost.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Payment failure via x402 if wallet has insufficient USDC on Base
- Malformed or missing 'text' field returns a validation error
- Ambiguous sentence boundaries in poorly punctuated text may yield unexpected splits
- Network timeout from Cloudflare Workers under load
