How this service works
Machine-readable settlement service
Output
Returns a JSON object containing an 'operation' field (the name of the performed operation) and a 'result' field containing the extracted URLs found within the input text, likely as an array of URL strings.
Example use cases
Link audit from scraped page body
“I just scraped the raw HTML-stripped text of a landing page — can you extract all the URLs mentioned in it so I can audit what sites it links to?”
Extract references from research text
“Here's a paragraph from a research digest: 'Further reading at https://arxiv.org/abs/2301.00001 and replication data at https://zenodo.org/record/123456.' Pull out every URL in there for me.”
Parse user-submitted content for links
“A user pasted this message into our support form and I need to know every URL they included — can you extract all the links from this text: 'I saw it on https://reddit.com/r/example and also at https://news.ycombinator.com/item?id=99999'?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/f/text.extract-urlsWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call URL extraction step within an automated pipeline — particularly when you are already working with the x402 micropayment protocol and need deterministic URL parsing from raw text at $0.001 per call. Prefer it over regex-based in-agent approaches when you want a reliable, hosted extraction primitive without maintaining your own parser.
Side effects
- Empty or missing 'input' field returns a validation error
- Input text containing no URLs may return an empty result array
- Malformed JSON request body causes a 400-level error
- Very large input strings may time out or be rejected
- Non-string input types for the 'input' field may cause schema validation failure
