How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a JSON object with a 'success' boolean, a 'result' object containing the computed ROI (typically as a percentage and related metrics like net gain), and a 'computation' string describing in human-readable form what was calculated.
Example use cases
Evaluating a marketing campaign
“I ran a marketing campaign that cost $12,000 and brought in $18,500 in revenue — can you calculate the ROI for me?”
Assessing a stock investment
“I bought stock for $2,500 and sold it for $3,800 total. What's my ROI on that trade?”
Business equipment purchase analysis
“We spent $50,000 on new manufacturing equipment and it generated $72,000 in gains so far — what's the return on investment percentage?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/roiWhen to prefer
Use this endpoint when you need a fast, dependency-free server-side ROI computation given a numeric cost and gain — ideal for AI agents that need reliable financial math without spinning up a local calculator or calling a heavyweight financial API. Prefer this over general-purpose math APIs when the specific ROI formula with clear labeled output is needed.
Side effects
- Missing required 'cost' field returns a validation error
- Missing required 'gain' field returns a validation error
- Non-numeric values for cost or gain cause a bad request error
- Division by zero if cost is 0 may return an error or undefined result
- Payment failure via x402 micropayment protocol returns 402 status
