Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/f/text.truncateWhen to prefer
Choose this endpoint when you need a simple, pay-per-call text truncation operation without deploying your own string-processing logic — particularly useful in agent pipelines where text fields must conform to strict length constraints before being passed to downstream APIs or UI components. It is ideal for lightweight, one-off truncation tasks billed at $0.001 USDC via the x402 payment protocol.
Side effects
- Missing 'input' object in request body returns a validation error
- Missing 'text' or 'max' sub-fields within the input object may cause a processing error or unexpected output
- Non-numeric 'max' value may result in an error or undefined behavior
- Empty text string may return an empty result or a no-op
- Service unavailable if the Vercel deployment is down or cold-starting
