Delx In Range is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).
Checks whether an integer value falls within a specified [min, max] range, returning a boolean result.

How this service works
Check whether a value sits in [min,max]. Call when you preflight budgets, scores, or clamp decisions. Returns boolean in_range with bounds 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 `in_range` field indicating whether the value falls within the [min, max] range, along with the supplied min and max bounds for reference.
Example use cases
Budget cap preflight check
“Before I approve this spend, check if 850 is within my budget range of 500 to 1000.”
Score validity check for agent output
“My agent returned a confidence score of 112 — verify whether that's within the valid range of 0 to 100.”
Sensor reading bounds validation
“The temperature sensor reported 37 — is that within the acceptable operating range of 20 to 80?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/in-range?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, stateless, pay-per-call numeric range check without setting up any infrastructure or libraries. Ideal for agent preflight steps before applying budget caps, clamping scores, or gating decisions on whether a value is within bounds. Prefer it over custom code when operating in a lightweight agentic context where local compute is unavailable or undesirable.
Side effects
- Missing required fields (value, min, or max) result in a validation error
- Non-integer inputs may be rejected or cause unexpected behavior
- Payment failure via x402 prevents the call from completing
- If min is greater than max, behavior may be undefined or return an error
