Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.lines-dedupe--unique-linesWhen to prefer
Use this endpoint when you need a quick, cheap ($0.001 USDC) programmatic way to deduplicate lines in a text blob — especially in agentic pipelines where paying per-call via x402/USDC is already set up. Prefer this over local string manipulation when the deduplication needs to happen server-side in a stateless, API-driven workflow.
Side effects
- Missing required 'input' field returns an error
- Non-string input type may cause a validation error
- Empty string input may return an empty result
- Payment failure (402) if USDC balance is insufficient or x402 auth is missing
- Large inputs may hit size or timeout limits
