Returns a JSON object with an 'ok' boolean field indicating whether the supplied UK postcode is valid (true) or invalid (false).
Example use cases
E-commerce checkout address validation
“Before we process this order, check if the postcode 'EC1A 1BB' that the customer entered is actually a valid UK postcode.”
User registration form verification
“A user just signed up with the postcode 'XY99 9ZZ' — can you validate whether that's a real UK postcode before we save their profile?”
Bulk data cleanup for UK addresses
“I have a UK address record with postcode 'W1A 0AX' — can you confirm it's valid so I know whether to keep or flag this entry?”
