How this service works

Pay-per-call utilities for autonomous agents, paid with x402 (USDC on Base; no account, no API key).

Output

A JSON object containing an array of chunk objects, each with its text content, character length, start/end byte offsets, approximate token count, zero-based index, and heading path (breadcrumb of parent headings for markdown mode). Also returns summary fields: total chunks, total characters, input characters, overlap, maxChars, and detected or specified mode.

Example use cases

RAG pipeline document ingestion

“Take this 50,000-character markdown documentation page and split it into chunks of up to 2000 characters with 200-character overlap — I need each chunk to carry its heading path so I can store them in my vector database.”

LLM context window preparation

“I have a long plain-text article that's too big for a single LLM call — break it into chunks of at most 1000 characters with 100-character overlap so I can feed them one at a time.”

Token-budget-aware text segmentation

“Split this markdown README into chunks no bigger than 800 characters with 50-character overlap, using markdown mode so heading structure is preserved, and tell me the approximate token count for each chunk.”

When to prefer

Choose this endpoint when you need deterministic, structure-aware text chunking with heading-path metadata for markdown documents, especially in RAG or embedding pipelines where preserving section context matters. It is ideal for agents that cannot install local libraries and need a pay-per-call, zero-account-setup solution via x402 USDC micropayments on Base.

Side effects

overlap >= maxChars/2 returns a validation error
text exceeding 1 MB is rejected
invalid mode enum value returns a 400 error
missing required 'text' field returns a 400 error
payment failure or insufficient USDC balance returns a 402 Payment Required response
