Text Chunking API
x402
Text Chunking API is a paid API for AI agents from x402-gateway-production-1f21.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).
Splits a large text string into overlapping or non-overlapping chunks of a specified size for RAG ingestion and downstream processing

How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON response with an array of text chunks derived from the input, split according to the requested size and overlap parameters, ready for embedding or downstream NLP tasks.
Example use cases
RAG pipeline document prep
“Take this research paper text and chunk it into 1000-character pieces with a 100-character overlap so I can embed each chunk and load them into my Pinecone index.”
Semantic search index building
“I need to break this product documentation text into 300-character segments with no overlap so I can run embeddings on each piece for our search engine.”
LLM context window management
“This support transcript is too long to fit in one prompt — can you split it into 800-character chunks with 80 characters of overlap so I can process it section by section?”

Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/text/chunk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, machine-payable text chunking at $0.001 USDC per call via x402 protocol, especially in automated agent pipelines that need to prepare text for RAG ingestion, vector embedding, or LLM context windowing without standing up your own chunking infrastructure.
Side effects
- Text exceeds 500,000 character limit — returns validation error
- Chunk size outside allowed range (50–50,000) — returns schema validation error
- Overlap exceeds chunk size — may return error or unexpected behavior
- Missing required 'text' field — returns 400 bad request
- Payment not provided or insufficient — returns x402 payment required response
