How this service works
Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.
Output
Returns a JSON object with a letter-style grade (e.g. 'strong'), a numeric score (0-100), the source note confirming deterministic in-process calculation, a list of weighted metric drivers with individual scores and notes (e.g. DSCR), computed metrics including expected profit, break-even units, and contribution margin percentage, any warnings, the calculator name used, and a plain-English recommendation.
Example use cases
Example prompt
“Can you run a contribution margin analysis on my product — it sells at $140/unit, variable costs are $40/unit, fixed costs are $58,000/month, and I expect to sell 1,200 units this month? I want a viability grade and the break-even unit count.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/contribution-margin-calculatorWhen to prefer
Choose this endpoint when you need a fast, deterministic, no-upstream-API contribution margin and break-even calculation with a graded viability score — ideal for agent workflows evaluating unit economics, underwriting small business financials, or stress-testing product pricing without calling an external financial data provider. Prefer it over LLM-based financial reasoning when you need a reproducible numeric score and structured driver breakdown.
Side effects
- Missing required financial inputs returns a validation error
- Division by zero if unit price equals variable cost (zero contribution margin)
- Negative or illogical input values may produce warnings or an error grade
- Payment failure via x402 if USDC balance is insufficient results in 402 response
- Malformed JSON body returns a 400 bad request
