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: roi_percent (the ROI as a percentage, e.g. 20 meaning 20%), profit (the absolute profit as proceeds minus cost, e.g. 20), and a notice disclaimer clarifying the calculation is from supplied inputs only and does not constitute tax, investment, or lending advice.
Example use cases
Marketing campaign ROI check
“We spent $25,000 running ads last quarter and brought in $31,500 in sales — what's the ROI percentage and profit?”
Equipment purchase return analysis
“I bought a piece of machinery for $8,000 and it generated $11,200 in revenue. Can you tell me the ROI and how much profit that is?”
Startup project profitability check
“Our startup spent $150,000 developing a feature and earned $180,000 from it — what's the return on investment percentage and net profit?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/finance/roi?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, server-side ROI and profit computation from raw cost and proceeds figures, especially in automated agent workflows where a deterministic calculation is preferable to doing floating-point arithmetic locally. It is ideal for agents that need an audit-friendly, third-party-computed result with a built-in disclaimer, and where a micropayment-per-call model (x402) is acceptable.
Side effects
- Missing required 'cost' or 'proceeds' fields returns a validation error
- Cost of zero or below (exclusiveMinimum:0 enforced) will be rejected
- Proceeds value below 0 will fail schema validation
- Extremely large numbers near the maximum boundary may result in floating-point precision artifacts
- Payment not included or insufficient USDC will result in 402 Payment Required response
