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 three fields: 'selling_price' (cost plus the marked-up amount), 'profit' (the markup amount in the same currency units), and a 'notice' disclaimer clarifying the result is a pure arithmetic calculation with no tax, investment, or lending advice.
Example use cases
Retail product pricing check
“I'm pricing a product that costs me $120 to make — what would the selling price and profit be if I mark it up by 35%?”
Wholesale order margin estimate
“My wholesale cost for a batch is $4500 and I want to apply a 20% markup — what's my profit and the price I should charge?”
Quick freelance quote markup
“My base cost for a project is $850 and I want to add a 15% markup — what selling price should I quote the client and how much profit does that give me?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/finance/markup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a fast, disposable, server-side arithmetic computation of selling price and profit from a cost and a markup percentage — especially inside automated pricing workflows or agent pipelines where avoiding local float errors matters. Prefer this over local computation when you need a consistent, API-enforced result with a built-in disclaimer that no financial advice is implied.
Side effects
- cost or markup_percent outside allowed bounds (cost > 1,000,000,000,000 or markup_percent > 1000) returns a validation error
- missing required fields returns a 400-level error
- floating-point precision issues may arise for very large or very precise cost values
- payment not sent or insufficient USDC returns 402 Payment Required
