How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
A JSON object containing a boolean 'ok' field indicating success, the original expression string echoed back as 'expr', and the computed numeric 'result' as a floating-point number. Example: {ok: true, expr: 'sqrt(144)+2^3*pi', result: 43.13}.
Example use cases
Evaluating complex scientific formula
“What is the result of sqrt(256) + log(1000) * pi^2?”
Quick arithmetic for financial modeling
“Calculate (1500 * 0.07) + (2000 / 12) * 3 for me so I can use it in my report.”
Verifying student math homework
“Can you check what 5! + sqrt(81) - 2^4 evaluates to? I want to verify my answer of 113.”

Endpoint
GEThttps://anibalb.duckdns.org/x402/math-solve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to evaluate arbitrary mathematical expressions — especially those involving functions like sqrt, powers, pi, and chained operations — without setting up a local math parser or code execution environment. It is ideal for agents that need quick, reliable numeric answers from formula strings at low cost ($0.002/call) and without API key management.
Side effects
- Invalid or unparseable expression string returns an error response
- Division by zero or undefined mathematical operations may return an error
- Malformed query parameter causes a 400-level response
- Network timeout or service unavailability returns a 5xx error
- Expressions referencing unsupported functions may fail silently or return an error
