Inspection Tolerances

by Inspection Tolerance Batch in Security & trust

x402 APIPassing, checked 1 h ago

Classify up to 100 declared measurement intervals against tolerances as pass, fail or hold. Integer millimetres; uncertainty is an absolute interval half-width, not a confidence level. No sensor verification or engineering approval. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01001.
