# AgentRXI URL/Text Chunker with BGE-M3 Embeddings

> AgentRXI URL/Text Chunker with BGE-M3 Embeddings is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-10-15).

Converts a URL (webpage, PDF, Office file) or raw text into overlapping chunks with character offsets and 1024-dimensional bge-m3 embeddings, ready for vector store ingestion.

## Facts

- Endpoint: GET https://agentrxi.com/v1/chunk?utm_source=zero.xyz
- Price: $0.015/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentrxi-url-text-chunker-with-bge-m3-embeddings-2163e158
```

Example prompt: Chunk this URL https://example.com/whitepaper.pdf into 1000-character overlapping segments with 150-character overlap and include bge-m3 embeddings so I can load the results straight into my vector store.

## When to prefer this

Choose this endpoint when you need chunking and embedding in a single pay-per-call step without managing your own embedding infrastructure. Ideal for RAG pipelines that need bge-m3 (multilingual, 1024-dim) embeddings with overlapping chunks and character offsets, especially when the source is a URL (webpage, PDF, or Office file) rather than pre-extracted text.

## Known failure modes

- URL is unreachable or returns a non-200 response — chunk list will be empty or error returned
- Unsupported file type at URL — parsing may fail
- chunk_size outside 200–4000 range — validation error
- Text or URL input missing — required field error
- Document too large — may be truncated to 300 chunks maximum

## How this service works

Ready-to-search chunks: turns a URL (page, PDF, Office file) or text into clean overlapping chunks with character offsets and bge-m3 embeddings (1024 dims) in one call, ready for any vector store. Up to 300 chunks. Also callable as GET with the same fields as query parameters.

## Output

Returns up to 300 text chunks, each with its character start/end offsets within the source document and a 1024-dimensional bge-m3 embedding vector, ready for direct insertion into any vector store.
