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 input value, the lower and upper thresholds, a state string indicating whether the value is 'below_lower', 'within_range', or 'above_upper', and a boolean 'triggered' flag indicating whether the value fell outside the defined bounds.
Example use cases
Sensor reading out-of-range alert
“I have a temperature sensor reading of 87 degrees — can you check if it's within the safe range of 60 to 80 and tell me if it's triggered?”
Credit score boundary check
“Is a credit score of 620 within the acceptable range of 650 to 850? Tell me if it's below the lower threshold.”
Battery level low detection
“My device battery is at 8 percent. Check if that's below the lower threshold of 20 percent and flag it as triggered if so.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/signal-threshold?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call numeric range classification without standing up your own logic — ideal for agent workflows that need to gate decisions on whether a metric is in, above, or below a defined band. Prefer this over custom code when you want verifiable, on-chain-paid, stateless threshold checks at $0.003 per call.
Side effects
- Missing required 'value' field returns a validation error
- Non-numeric input for value/lower/upper results in a type error
- If neither lower nor upper are provided, classification may be trivial or undefined
- Payment failure via x402 prevents call execution
