How this service works
Arithmetic expression evaluator (+ - * / % ^ and parentheses). GET /calc?expr=(2%2B3)*4 → {result}. Deterministic JSON, instant, no code execution.
Output
A JSON object containing a single 'result' field with the numeric value of the evaluated arithmetic expression. Response is deterministic — same expression always yields the same result.
Example use cases
Example prompt
“What is the result of (15 + 7) * 3 - 2^4 modulo 10? Just evaluate that arithmetic expression and give me the number.”
Technical details
Endpoint
GEThttps://aniccanomac-mini-1.tail7a0ba4.ts.net/calcWhen to prefer
Use this endpoint when you need to evaluate a user-provided or dynamically constructed arithmetic expression and want a deterministic, sandboxed result without executing arbitrary code. Ideal when the expression uses standard operators (+, -, *, /, %, ^) and parentheses. Prefer over general code execution for safety, speed, and simplicity.
Side effects
- Malformed or invalid expression returns an error response
- Division by zero may return an error or infinity
- Unsupported operators or functions beyond the supported set (+, -, *, /, %, ^) return an error
- URL encoding issues with special characters like + (must be encoded as %2B) may cause incorrect parsing
- Empty or missing expr parameter returns an error
