How this service works
Choose the singular or plural form for a given count, e.g. (apple, 3) → "apples", (apple, 1) → "apple". By default the count is prepended ("3 apples"); set includeCount=false to omit it.
Output
A string containing the correctly inflected singular or plural form of the noun. By default the count is prepended (e.g. '3 apples', '1 apple'); if includeCount is set to false, only the bare inflected word is returned (e.g. 'apples', 'apple'). Handles English irregular forms correctly.
Example use cases
Dynamic UI label generation
“I need to display a message like '1 file uploaded' or '3 files uploaded' depending on how many files the user selected — can you use the inflect service to get the correctly formatted phrase for 'file' with a count of 3?”
Irregular noun pluralization for reports
“I'm building a summary report and need to say how many people attended — can you inflect 'person' with a count of 42 so it shows up as '42 people'?”
Zero-count edge case formatting
“What does the inflect API return for 'apple' with a count of 0? I want to make sure my app correctly shows '0 apples' and not '0 apple'.”

Endpoint
POSThttps://inflect.openverbs.com/v1/countWhen to prefer
Use this endpoint when you need grammatically correct singular/plural noun forms tied to a specific numeric count, especially when you also want the count prepended in a single formatted string. Prefer this over the plain plural/singular sibling endpoints when you have a concrete quantity at hand and want a ready-to-display phrase like '3 apples' or '1 apple' without assembling the string yourself.
