Example use cases
Clean up scraped URL list
“I scraped a bunch of URLs from a site and there are tons of duplicates — can you remove all the repeated lines and just give me the unique ones? Here's the raw list: 'https://example.com/page1
https://example.com/page2
https://example.com/page1
https://example.com/page3'”
Deduplicate log file entries
“I have a log snippet with repeated error messages and I only want to see each unique line once. Can you deduplicate this for me: 'ERROR: timeout
INFO: connected
ERROR: timeout
WARN: retry
INFO: connected'”
Filter unique product tags
“I've got a big messy list of product tags with lots of repeats — can you strip out the duplicates and return only the unique tags? The list is: 'electronics
clothing
electronics
furniture
clothing
toys

Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.lines-dedupe--remove-duplicate-linesWhen to prefer
Use this endpoint when you need a simple, low-cost ($0.001 USDC) API call to deduplicate lines in a text string without setting up local string processing logic. Ideal for agents operating in pay-per-use microtransaction environments (x402 protocol) that need lightweight, stateless text cleaning as part of a pipeline.
Side effects
- Missing 'input' field returns a validation error
- Empty string input may return an empty response or pass through unchanged
- Very large text inputs may hit payload size limits
- Network or Vercel cold-start latency may cause timeouts
- Payment failure via x402 protocol prevents the call from completing
