How this service works
Call when an agent needs markdown links extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/regex-markdown-link first.
Output
Returns a list of up to 20 matched markdown links found in the input text, each containing the link label/text and the target URL. An empty list is returned (and still billed) if no markdown links are found.
Example use cases
Audit links in markdown documentation
“Go through this markdown README and pull out every hyperlink so I can check which ones need updating: '# Welcome
See [installation guide](https://docs.example.com/install) and [changelog](https://docs.example.com/changelog) for details.'”
Scrape references from a parsed webpage
“I grabbed the raw markdown from a blog post — can you extract all the markdown links from it so I can see which external sites it references? Here's the content: 'Read more at [TechCrunch](https://techcrunch.com) and [Wired](https://wired.com). Also see [this study](https://arxiv.org/abs/1234.5678).'”
Build a link index from agent-generated report
“My agent just produced a markdown report and I need a list of every link it included. Extract all the markdown hyperlinks from this: 'Results: [Dataset A](https://data.gov/a), [Dataset B](https://data.gov/b), and [methodology](https://example.com/method.pdf).'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-markdown-link?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, deterministic regex-based extraction of markdown hyperlinks from text without any LLM or network calls. Ideal for pipelines that process markdown documents, READMEs, or agent-generated reports where you need a structured list of links quickly and cheaply. Prefer the free sandbox POST /v1/sandbox/regex-markdown-link endpoint for testing before committing to paid calls.
Side effects
- Empty match list returned with charge if no markdown links exist in the text
- Text exceeds 100,000 character limit — request rejected
- Text is empty or missing — request rejected
- More than 20 links present — only first 20 matches returned, remainder silently truncated
- Malformed markdown links (e.g. missing closing parenthesis) may not be matched by regex
