How this service works
A compact x402 utility surface for agents that need cheap, repeatable non-LLM transformations before spending on heavier routes: CSV cleanup, JSON Schema checks, timestamp conversion, JWT decode, URL normalization, hashes, codecs, and text utilities.
Output
Returns a JSON object with 'ok' true, the tool name, the original input, and a 'result' object containing: 'uniqueText' (the deduplicated text as a single string), 'uniqueLines' (array of unique lines), and 'removedCount' (integer count of how many duplicate lines were removed).
Example use cases
Deduplicating scraped keyword lists
“I scraped a bunch of keywords from multiple pages and combined them into one list — can you remove all the duplicate lines from it? Treat comparisons as case-insensitive and trim any extra spaces.”
Cleaning up a user-submitted tag list
“A user submitted a form with tags separated by newlines and there are a bunch of repeats. Strip out the duplicate lines for me — case-insensitive — and tell me how many were removed.”
Normalizing log entries before processing
“I have a block of log lines and want to deduplicate them before further analysis. Remove repeated lines with trimming enabled and case-sensitive matching, and give me back the unique lines.”
Technical details
Endpoint
POSThttps://x402-utils.558686.xyz/v1/tools/unique-lines?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap ($0.002 USDC), deterministic, non-LLM deduplication of newline-separated text with control over trimming and case sensitivity. Prefer it over LLM-based approaches for speed, cost, and reproducibility. Use it as a preprocessing step before heavier analysis or storage operations.
Side effects
- Empty or missing 'text' field may return an error or empty result
- Very large text inputs may exceed size limits or time out
- Malformed JSON body returns a 4xx error
- Payment failure or insufficient USDC balance returns HTTP 402
