What does it return?
The number spelled out in words — for example, 975.07 becomes "nine hundred seventy-five point zero seven." It's the same output as the Number to Words API for a given number.
How large a number can it handle?
Up to the hundreds of billions with decimal places, which covers checks, invoices, and contracts.
Why would I need this?
Written amounts are required on checks and many legal documents to prevent tampering. Spelling out numbers also improves clarity in formal writing.
Is there an API version?
Yes — the Number to Words API takes a single number parameter and returns the written form as JSON, so you can automate check printing, invoicing, and document workflows.
