JSON Numeric Range Check
x402
JSON Numeric Range Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Validates and checks selected numeric fields in a JSON object against caller-supplied inclusive minimum and maximum bounds, returning counts and normalized values as deterministic versioned JSON.

How this service works
JSON Numeric Range Check: JSON Numeric Range Check checks selected numeric fields against inclusive bounds from bounded caller-supplied values without an external provider. Call JSON Numeric Range Check before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Numeric Range Check as versioned deterministic JSON. Price: $0.00…
Output
Returns a deterministic versioned JSON result containing: which fields were checked, counts of in-range and out-of-range values, normalized values clamped or flagged against the supplied bounds, and a versioned result contract identifier. No data is retained after processing.
Example use cases
Preflight check before downstream tool
“I'm about to pass this structured pricing plan to our invoicing system which only accepts amounts between 0.01 and 9999.99 — can you check the 'amount', 'discount', and 'tax' fields are all within those bounds first?”
Validate agent-generated sensor data
“My agent generated this JSON batch of temperature readings. Please check that 'temp_celsius' and 'humidity_percent' are within 0–100 for humidity and -40 to 85 for temperature, and tell me how many are out of range.”
Enforce scoring rubric bounds
“This JSON has a 'score' and 'confidence' field from my evaluation pipeline — make sure both are between 0 and 1 inclusive, and give me the count of any violations.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-numeric-range-checkWhen to prefer
Use this endpoint when you need a lightweight, stateless, pay-per-call numeric bounds validator for JSON objects — especially as a preflight gate before passing structured data to a downstream tool with strict numeric contracts. Prefer this over building custom validation logic when you need deterministic, versioned results with counts and normalization included. It is not a substitute for full JSON Schema validation or type-checking services.
Side effects
- Missing required fields array or object body returns an error
- Minimum value greater than maximum value may cause validation error or undefined behavior
- Non-numeric values in specified fields may be skipped or cause field-level errors
- Exceeding 256 fields in array or 128 properties in object may result in truncation or rejection
- Payment not supplied (x402 protocol) results in 402 Payment Required
