Returns a structured decision framework for whether a business should approve or refuse a growth adjacency move, including the governing rule, required inputs, recommended action, and a validation check.

## 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-adjacency-decision-rule-87a5e6e7
```

Example prompt: We're a SaaS company at around $8M in revenue and we're considering moving into a adjacent vertical — can you run the adjacency decision framework and tell me the rule, what inputs I need to gather, whether to approve or refuse, and what check I should run afterward?

## When to prefer this

Use this endpoint when an AI agent is advising a business (launch to ~$50M revenue) on a specific growth decision involving an adjacency move — i.e., whether to enter an adjacent market, product line, or customer segment. Prefer this over generic strategy advice when you need a structured rule-based decision output with clear inputs, an action directive, and a validation check. It is particularly useful when preparing board-level recommendations or running systematic growth reviews. For businesses outside this revenue range or for non-adjacency growth decisions (e.g. pricing, pace), use the sibling endpoints instead.

## Known failure modes

- No query parameters required so malformed requests are unlikely; service may return a generic error if the endpoint is unavailable
- Rate limiting or payment failure (x402) if USDC payment is not properly attached
- Stale or cached content if the framework version is outdated
- Response may lack specificity if the caller's business context is not incorporated (the endpoint returns a general framework, not a customized recommendation)

## How this service works

Business Frameworks · business-frameworks/growth/decide/adjacency@1.2 — the decision rule for approving or refusing an adjacency, as inputs, rule, action and check: four screens, one of them that the offer creates value for a defined segment, and seven failure patterns. Call when a move beyond the core is proposed and has to pass the screens; returns 257 tokens of original synthesis citing three published works — to run it on your own numbers, POST /apply/growth/decide/adjacency.

## Output

Returns approximately 220 tokens of original synthesis covering: the governing rule for adjacency decisions, the inputs the decision requires, the recommended action (approve or refuse), and a post-decision check to validate the outcome — plus public citations and handles to child framework nodes for further exploration.
