## 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 business-frameworks-market-split-test-pattern-f1c431cf
```

Example prompt: I have a candidate business node that could be one thing or two — use the Matryoshka Business Frameworks split-test pattern to tell me the decision rule for whether to split it based on whether the pieces sell into different markets to different buyers.

## When to prefer this

Use this endpoint when an agent or analyst needs a canonical, authoritative decision rule for node-splitting in a business framework context — specifically when the question is structural (one node vs. two) rather than financial or operational. Prefer this over generic strategy APIs when the Matryoshka Paradigms business-frameworks vocabulary is already in use, or when the decision hinges on market-buyer alignment rather than revenue thresholds or product categories.

## Known failure modes

- Network timeout from Cloudflare Workers edge
- Payment not processed (x402 payment required, $0.03 USDC)
- Invalid or missing query parameters causing malformed request
- Rate limiting if quota exceeded
- Endpoint returns empty or truncated synthesis due to upstream content error

## How this service works

Business Frameworks · business-frameworks/market/pattern/split-test@1.2 — the chain pattern for deciding a split: two nodes only when the pieces sell into different markets to different buyers; one node when the same buyer takes both under the same constraint — the buyer decides, the engineer does not. Call when a candidate node could be one thing or two; returns 279 tokens of original synthesis (terse variant 106) with related handles; free layer at /catalogue.

## Output

Returns approximately 279 tokens (or a terse 106-token variant) of original synthesis articulating the chain pattern rule: split into two nodes only when pieces sell into different markets to different buyers; keep as one node when the same buyer takes both under the same constraint. Includes related framework handles for further navigation.
