Clip username or bio for profile display
“Our profile page only shows 60 characters for the bio — can you cut this down: 'Passionate software engineer, open-source contributor, coffee lover, and occasional blogger about distributed systems'?”

Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.truncate--shorten-to-charactersWhen to prefer
Choose this endpoint when you need a simple, reliable, pay-per-call text truncation operation without setting up your own string-processing logic. It is well-suited for agents that occasionally need to clip text to fit UI constraints, character limits, or storage schemas, and want a lightweight, stateless microservice rather than a full NLP pipeline.
Side effects
- Missing or empty input text returns a validation error
- Character limit not provided or non-numeric causes a bad request
- Input object schema mismatch returns a 400 error
- Payment not included or insufficient results in a 402 Payment Required response
- Very large input strings may cause timeout or oversized payload errors
