Delx Approx Eq
x402
Delx Approx Eq is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Checks whether two floating-point numbers are approximately equal within a specified tolerance, returning a boolean equal flag along with the inputs.

How this service works
Approximate equality within tolerance. Call when you compare floats from agent math without exact-equality traps. Returns equal flag, a, b, tolerance for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object containing a boolean 'equal' flag indicating whether the two numbers fall within the specified tolerance of each other, plus the original input values a, b, and tolerance for reference.
Example use cases
Float rounding check in agent pipeline
“I just computed two separate paths through a pricing formula and got 19.99999998 and 20.0 — can you check if those are approximately equal within a tolerance of 0.00001?”
Validate physics simulation output
“My simulation returned 9.80664 for gravitational acceleration and I expected 9.80665 — are those close enough to be considered equal with a tolerance of 0.0001?”
Financial calculation drift detection
“Two different fee calculation methods gave me 1234.5670001 and 1234.567 — check if they're approximately equal within 0.001 so I can decide if the difference matters.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/approx-eqWhen to prefer
Choose this endpoint when your agent performs floating-point arithmetic and needs to avoid exact-equality pitfalls common with IEEE 754 floats. It is ideal for lightweight, stateless numerical comparisons within an agentic pipeline where you want a definitive advisory signal without implementing epsilon-comparison logic yourself. At $0.001 USDC it is cost-effective for high-frequency checks in automated workflows.
Side effects
- Missing required fields (a, b, or tolerance) result in a validation error
- Non-numeric inputs for a, b, or tolerance will be rejected
- Negative tolerance values may produce unexpected behavior
- Payment failure via x402 will block the request
- Extremely large or NaN/Infinity float values may cause edge-case errors
