How this service works
Format a non-negative integer as an ordinal — both the suffixed form (21st) and the ordinal words (twenty-first).
Output
Returns the ordinal string representation of the submitted integer (e.g., 1 → '1st', 2 → '2nd', 11 → '11th', 101 → '101st'), suitable for direct use in UI labels, text generation, or announcements.
Example use cases
Leaderboard position labeling
“I have a user ranked 12 on our leaderboard — can you give me the ordinal for 12 so I can display it as '12th place'?”
Event milestone announcement
“We're celebrating our 1000th customer — can you convert 1000 to its ordinal form so I can write '1000th customer' in the announcement?”
Dynamic sports bracket display
“A player just finished in position 3 in the tournament — give me the ordinal for 3 so I can show '3rd' on the bracket UI.”

Endpoint
POSThttps://numeral.openverbs.com/v1/ordinalWhen to prefer
Choose this endpoint when you need a fast, reliable, pay-per-call conversion of a single integer to its ordinal suffix (1st, 2nd, 3rd, etc.) without setting up a local library or NLP pipeline. Ideal for serverless agents and workflows that occasionally need ordinal formatting without bundling string-manipulation dependencies.

- Non-integer or negative values rejected by schema validation
- Missing 'number' field in body results in a 400-level error
- Network or service downtime returns a 5xx error
