Delx Commerce Approximate Equality Check
x402
Delx Commerce Approximate Equality Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Checks whether two numbers are approximately equal within a given tolerance, returning a boolean result

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the original inputs (a, b, tolerance), and a boolean 'equal' field indicating whether the two numbers are within the specified tolerance of each other, along with a schema identifier string.
Example use cases
Floating point price validation
“Check if the computed total of 99.9997 is close enough to the expected price of 100.0, using a tolerance of 0.001 — are they approximately equal?”
Sensor measurement tolerance check
“I have two sensor readings: 23.45 and 23.451. Are they approximately equal within a tolerance of 0.005?”
Algorithm output verification
“My algorithm computed 3.14159 and the reference value is 3.14160 — can you check if those are approximately equal with a tolerance of 0.0001?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/approx-eq?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call numeric approximate equality check without standing up your own math utility, especially within an agent pipeline that already uses x402/USDC micropayments on Base or Solana. Useful for validating floating point computations, sensor readings, or financial figures where exact equality is unreliable due to precision limits.
Side effects
- Missing required fields (a, b, or tolerance) result in an error response
- Non-numeric values for a, b, or tolerance cause a validation error
- Payment failure via x402 protocol prevents the call from completing
- Network timeout if the service is temporarily unavailable
