How this service works
Evaluate a math expression
Output
Returns a JSON object containing the numeric result of the evaluated expression, the original expression string echoed back, the variable values used in evaluation, a unique request ID, and a list of related agentutil services.
Example use cases
Example prompt
“Calculate the value of the expression '3 * x^2 + 2*x - 5' where x = 4, and give me the numeric result.”
Technical details
Endpoint
POSThttps://math.agentutil.net/v1/evaluateWhen to prefer
Use this endpoint when you need to programmatically evaluate a math expression — especially one that contains variables whose values are known at runtime. Prefer it over a general-purpose LLM math answer when you need a deterministic, exact numeric result. It handles standard arithmetic, operator precedence, and common math functions like sqrt.
Side effects
- Invalid or unparseable expression returns an error
- Division by zero in the expression may return an error or Infinity
- Referencing an undefined variable without providing it in the variables map may fail or return NaN
- Malformed JSON body returns a 400-level error
- Payment not included or insufficient causes a 402 Payment Required response
