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 original value, min, max, the schema identifier (delx/util-in-range/v1), and an 'in_range' boolean indicating whether the value falls within the specified bounds.

Example use cases

Sensor reading bounds check

“My temperature sensor just returned 72 — can you confirm it falls within the acceptable operating range of 60 to 80?”

Form input validation

“A user submitted the age value 17 — check if that's within our allowed range of 18 to 65 before we proceed.”

Game score validity check

“The player's score came back as 250 — verify that it's within the valid game score range of 0 to 500.”

When to prefer

Choose this endpoint when you need a lightweight, pay-per-call integer range check without setting up auth or managing subscriptions. Ideal for agent workflows that sporadically need numeric bounds validation and want verifiable, on-chain micropayment billing via USDC on Base or Solana.

Side effects

Missing required fields (value, min, or max) result in a validation error
Non-integer inputs may be rejected or coerced unexpectedly
Payment failure via x402 if USDC balance is insufficient
min greater than max may produce undefined or error behavior
