How this service works
Machine-readable settlement service
Output
A text response containing the original input lines with all duplicates removed, preserving only unique lines (order may be preserved or sorted depending on implementation). The response is a JSON object with the deduplicated text.
Example use cases
Clean up scraped URL list
“I scraped a bunch of URLs from a website and there are tons of duplicates in my list — can you remove all the repeated lines and give me just the unique URLs? Here's the full 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 file where a bunch of error messages appear multiple times — can you deduplicate the lines so I only see each unique error once? Here are the log lines: 'ERROR: connection timeout
INFO: retry attempt
ERROR: connection timeout
ERROR: disk full
INFO: retry attempt'”
Unique keyword list for SEO
“I've got a big keyword list for my SEO campaign but there are loads of repeats — please remove all the duplicate lines so I'm left with only unique keywords. The list is: 'best coffee shops
coffee near me
best coffee shops
latte art
coffee near me
cold brew'”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.lines-dedupe--deduplicate-linesWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call microservice to deduplicate lines in a text string without setting up any local processing. Ideal for agents that handle text cleanup tasks on-the-fly and want to offload string deduplication as a composable step in a pipeline, especially when already using the PennyRail/x402 payment infrastructure.

- Non-string input type may cause a schema validation failure
