How this service works
Machine-readable settlement service
Output
A structured object containing all URLs and hyperlinks found within the input text, typically as an array of extracted link strings parsed from the provided content
Example use cases
Link audit from scraped article
“I just scraped the body text of this news article — can you extract every URL mentioned in it so I can check which ones are broken or redirecting?”
Extract references from research paste
“Here's a chunk of raw text I copied from a research paper. Pull out all the URLs and links so I can compile a reference list.”
Harvest links from email body
“I have the plain-text body of a marketing email stored as a string — extract all the URLs from it so I can track which destinations were promoted.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.extract-urls--extract-linksWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call service to extract URLs from arbitrary text strings without setting up a full HTML parser or NLP pipeline. It is ideal for quick ad-hoc link extraction in agent workflows where the input is a raw text blob rather than a fully rendered web page.
Side effects
- Empty or whitespace-only input string returns an empty result or error
- Input that contains no URLs returns an empty links array
- Malformed or non-string input may return a 400 or schema validation error
- Extremely long input strings may hit payload size limits
- Payment authorization failure returns 402 if USDC balance is insufficient
