Example use cases
Shorten UI display text

Generate preview snippets
“Trim this blog post intro to 200 characters so I can use it as a meta description preview: 'In today's fast-paced digital landscape, businesses must adapt rapidly to shifting consumer demands, emerging technologies, and evolving regulatory environments that reshape how we work.'”
Clip user-generated content
“A user just submitted a bio that's way too long — can you truncate it to 100 characters max? Here it is: 'I am a passionate software engineer, avid coffee enthusiast, amateur photographer, and weekend hiker based in Portland, Oregon, always looking for new adventures.'”

Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.truncate--truncate-textWhen to prefer
Use this endpoint when you need a simple, reliable, paid micro-service for text truncation without building custom string-handling logic. Particularly useful in agentic pipelines where text must be clipped to fit UI components, API field limits, or preview snippets, and you want a stateless, idempotent operation billed at $0.001 USDC per call via x402.
Side effects
- Missing or malformed 'input' object returns a validation error
- No truncation parameters specified may result in no-op or error
- Payment failure or insufficient USDC balance causes 402 response
- Extremely large input strings may time out or be rejected
- Ambiguous truncation criteria (neither character nor word limit) may produce unexpected results
