How this service works
Machine-readable settlement service
Output
Returns a numeric value that has been clamped to the specified range — if the input was below the minimum it returns the minimum, if above the maximum it returns the maximum, otherwise returns the original value unchanged.
Example use cases
Clamp sensor reading to valid range
“I have a temperature sensor reading of -12.5 degrees but the valid range is 0 to 50 — can you clamp it so it fits within those bounds?”
Bound user-submitted score input
“A user submitted a score of 9999, but scores should only go from 1 to 10. Can you clamp that value to fit within the allowed range?”
Constrain animation progress value
“My animation progress value is 1.35 but it needs to stay between 0 and 1 — clamp it for me.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/number.clamp--bound-number?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, stateless numeric clamping operation executed as a paid micro-service call, particularly in agent workflows that already use the x402 payment protocol and PennyRail infrastructure. Prefer over implementing locally when consistency of behavior across distributed agent nodes is important.
Side effects
- Missing or malformed input object returns a validation error
- Non-numeric values in the input may cause computation failure
- Min greater than max may produce undefined or error behavior
- Payment failure via x402 protocol blocks execution with 402 status
