How this service works
Split long text into pieces for RAG retrieval. Strategies: 'sentence' packs whole sentences into a size budget and never splits mid-sentence; 'paragraph' prefers \n\n boundaries; 'fixed' is a hard char window with overlap. The highest-value endpoint for agents that build retrieval pipelines.
Output
An array of text chunk strings, each respecting the requested size budget and strategy: sentence-aware chunks never break mid-sentence, paragraph chunks split at double-newline boundaries, and fixed chunks are hard character windows with optional overlap.
Example use cases
Chunking docs for vector search
“I have a long legal document — about 200,000 characters — that I need to break into paragraph-aligned chunks of up to 1500 characters each so I can embed them in my Pinecone index. Can you chunk it using the paragraph strategy?”
Sliding window for dense retrieval
“Split this research paper into fixed 800-character windows with 150 characters of overlap so nothing important falls between chunk boundaries — I'm building a dense retrieval system.”
Sentence-safe chunking for chatbot KB
“I need to chunk these customer support articles into pieces no larger than 600 characters, but make sure you never cut mid-sentence — use the sentence strategy so the chunks read naturally when retrieved.”
Technical details
Endpoint
POSThttps://api.maximusmediahouse.com/v1/chunk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, rule-based text chunking without LLM calls — especially when sentence or paragraph boundary preservation matters for RAG quality. It is faster and cheaper than model-based chunkers and supports large inputs up to 1M characters. Prefer it over manual splitting when you need overlap control or unicode-safe segmentation.
Side effects
- Text exceeds 1,000,000 character limit — request rejected
- Overlap value equals or exceeds size value — invalid configuration error
- Invalid strategy enum value — validation error returned
- Empty text input — returns empty chunk array or error
- Network timeout on very large payloads close to the 1M char limit
