# Business Frameworks – Concentration Risk Decider

> Business Frameworks – Concentration Risk Decider is a paid API for AI agents from business-frameworks.matryoshka-paradigms.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Applies a deterministic concentration-risk rule to a business's customer and supplier share percentages, returning a structured risk decision with prioritized actions and citations.

## 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-concentration-risk-decider-a9589340 -d '<json body>'
```

Example prompt: My largest customer accounts for 42% of revenue and my largest supplier is 28% of my costs — can you run the concentration risk check on those numbers and tell me which dependencies are priced risks and what I should tackle first? I also have three owner-only functions: sales, banking, and key-account relationships.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, rule-based concentration risk assessment grounded in a specific business framework — no LLM variability, no subjective scoring. Ideal for due diligence workflows, pre-sale audits, or recurring risk reviews where repeatability and cited reasoning matter. Prefer over general AI analysis when you want a consistent threshold-based decision (the ~33% rule) with traceable citations.

## Known failure modes

- Missing required fields (largest_customer_share_pct or largest_supplier_share_pct) returns a 400 validation error
- Values outside 0–100 range for share percentages are rejected
- Malformed JSON body returns a parse error
- Payment not included or insufficient USDC causes 402 Payment Required
- Service unavailability returns 503

## Output

Returns a structured decision object indicating which customer and supplier dependencies cross the concentration threshold (default ~33.3%) and therefore represent priced risks, a prioritized list of recommended actions, the full decision rationale text from the underlying business framework node, and the node's public citations.
