# Cash Cycle Calculator – Business Frameworks

> Cash Cycle Calculator – Business Frameworks 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).

Computes the cash conversion cycle from receivable, inventory, and supplier-credit day-counts, identifies how many cents are tied up per sales dollar, and flags which lever to pull first.

## 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 cash-cycle-calculator-business-frameworks-99029fa2 -d '<json body>'
```

Example prompt: My business has 45 days receivable, 30 days inventory, and 20 days supplier credit; cost of sales is 60 cents per sales dollar and operating expenses are 25 cents per dollar — what is my cash conversion cycle, how much cash am I tying up per dollar of sales, and which lever should I pull first?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, rule-based cash cycle calculation with no AI hallucination risk — it is ideal for embedding working-capital diagnostics directly into a financial agent workflow, automating recurring cash health checks, or producing audit-friendly output with cited framework sources. Prefer it over generic LLM-based financial advice when reproducibility and citation traceability matter.

## Known failure modes

- Missing required fields (days_receivable, days_inventory, days_supplier_credit, cost_of_sales_per_sales_dollar, operating_expense_per_sales_dollar) returns a validation error
- Values outside allowed ranges (negative day-counts, ratios above 1.0) are rejected
- Malformed JSON body returns a 400-level error
- Payment not attached or insufficient USDC balance returns a 402 error

## Output

Returns the computed cash conversion cycle (in days), the cents tied up in working capital per sales dollar, a deterministic decision identifying the primary lever to pull (e.g. reduce receivable days, cut inventory, extend supplier terms), the rule-based rationale text, and public framework citations supporting the recommendation — all derived from the supplied numbers without any AI model involvement.
