Delx Commerce — JSON Numeric Range Check
x402
Delx Commerce — JSON Numeric Range 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).
Validates that specified numeric fields within a JSON object fall within a given minimum and maximum range, returning a pass/fail result with a list of invalid fields.

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 result object indicating whether all checked fields passed (passed: true/false), a list of invalid_fields that were out of range, an overall status ('pass' or 'fail'), and evidence metadata including a SHA-256 hash of the input, a flag confirming no data was retained, and a count of external calls made (always 0).
Example use cases
Sensor data bounds validation
“I have a JSON object with sensor readings — 'temperature', 'humidity', and 'pressure' — and I need to make sure all of them are between -50 and 150. Can you check which ones are out of range?”
E-commerce price integrity check
“Before we process this order payload, can you verify that the 'unit_price', 'shipping_cost', and 'tax' fields are all between 0 and 9999? Here's the object: {"unit_price": 29.99, "shipping_cost": 5.00, "tax": -2.00}.”
Survey score validation
“I've got a JSON response from a survey with fields 'satisfaction', 'nps_score', and 'effort_score'. All of them should be between 1 and 10. Can you tell me which ones, if any, are outside that range?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-numeric-range-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, verifiable, pay-per-call check that specific numeric fields in a JSON object satisfy a bounded range constraint — especially in automated agent workflows where auditability (via SHA-256 evidence) and no data retention are important. It is preferable to custom validation logic when you need an external, trustless attestation of range compliance, or when integrating with x402-compatible micropayment flows on Base or Solana.
Side effects
- Missing or malformed JSON object input returns a validation error
- Specifying field names that do not exist in the object may return them as invalid or be silently skipped
- Providing non-numeric values in fields listed for range checking may cause those fields to be flagged as invalid
- Exceeding maxProperties (128) or maxItems (256 fields) limits may result in a rejection error
- Missing minimum or maximum parameters may cause undefined range behavior
