How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object containing the original expression string and the evaluated numeric result as a double-precision floating point number.
Example use cases
Invoice total computation
“Calculate the total for me: (299.99 * 3) + (49.95 * 2) - 15 — I need to verify the line items on this invoice.”
Percentage discount calculation
“What is 1200 * (1 - 0.175)? I need to figure out the price after a 17.5% discount.”
Scientific formula evaluation
“Can you evaluate this expression for me: (9.81 * 75 * 12) / 2 — I need the kinetic energy result for a quick physics check.”
Technical details
Endpoint
GEThttps://api.geekvault.dev/dev-tools/v1/calculate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, serverless arithmetic evaluation without spinning up a math library or code interpreter. Ideal for AI agents that need to evaluate user-supplied formula strings at runtime, especially in environments where you want pay-per-call pricing with no API key management. Prefer this over a general-purpose code execution API when you just need fast arithmetic results with minimal overhead.
Side effects
- Invalid or malformed arithmetic expression returns an error
- Division by zero in the expression may cause an error or return Infinity
- Missing required 'expression' parameter returns a 400 Bad Request
- Unsupported operations or functions in the expression string may not be evaluated
- Payment failure via x402 returns a 402 Payment Required response
