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 boolean success flag, a result object containing the computed tax liability and bracket-by-bracket breakdown details, and a human-readable computation string describing what was calculated.
Example use cases
Freelancer annual tax estimate
“I made $87,500 freelancing this year. Calculate my tax using these brackets: 10% up to $11,000, 12% from $11,001 to $44,725, 22% from $44,726 to $95,375. How much do I owe?”
Comparing two tax bracket proposals
“I want to compare tax liability for a $150,000 income under two different bracket systems — first with brackets at 15%, 25%, and 35%, then with brackets at 12%, 22%, and 37%. Can you compute the total tax for each?”
After-tax salary negotiation tool
“My job offer is $112,000. Apply a progressive tax schedule with 10% on the first $20,000, 20% on $20,001–$80,000, and 30% on everything above $80,000 — what's my total tax bill and effective rate?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/taxWhen to prefer
Prefer this endpoint when you need a lightweight, serverless pure-math tax computation with no external data dependencies — ideal for agents doing financial planning, salary analysis, or tax simulation without needing a full tax platform integration. Best when you already have the bracket structure and want a fast, deterministic result for $0.10 USDC per call.
Side effects
- Missing required 'income' field returns validation error
- Missing or empty 'brackets' array causes computation failure
- Malformed bracket structure (missing rate or threshold fields) returns error
- Negative income values may produce unexpected results
- Payment failure via x402 micropayment returns 402 status before computation
