How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with the break-even quantity expressed as both whole units (ceiling) and fractional units (exact decimal), plus a disclaimer that the result is a floating-point calculation from supplied inputs only and does not constitute tax, investment, or lending advice.
Example use cases
Startup product pricing validation
“We're launching a new product with $80,000 in fixed overhead, selling at $40 per unit, and each unit costs $18 to make — how many do we need to sell before we break even?”
Retail margin planning
“My store has $12,000 in monthly fixed expenses. I sell items at $30 each with a variable cost of $22 per unit. What's my break-even unit count for the month?”
Freelance service rate check
“I have $5,000 in fixed monthly costs, I charge clients $500 per project, and my variable cost per project is $150. How many projects do I need each month to break even?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/finance/break-even?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, server-side break-even computation from raw cost inputs without building the formula yourself. It is ideal for AI agents embedded in financial planning, entrepreneurship, or pricing workflows where a lightweight, paid API call is acceptable and the user needs both exact and rounded unit counts instantly.
Side effects
- Missing required fields (fixed_cost, unit_price, or variable_cost) returns an error
- unit_price equal to or less than variable_cost results in a mathematically undefined or infinite break-even (division by zero or negative contribution margin)
- Values exceeding the maximum of 1,000,000,000,000 are rejected by schema validation
- Non-numeric input types are rejected
- Payment failure (402) if USDC micropayment is not fulfilled
