How this service works
Call when an agent needs http(s) URLs extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/regex-url first.
Output
Returns a list of up to 20 matched http/https URLs found in the submitted text. If no URLs are present, an empty match list is returned. The call is billed regardless of whether any matches are found.
Example use cases
URL harvesting from scraped pages
“I just scraped the raw HTML of a webpage — can you extract all the http and https URLs out of this content for me so I can follow them?”
Link extraction from email body
“Here's the body of a phishing email I received — find all the web URLs in it so I can investigate where it's trying to send people.”
Pulling references from a research document
“I have this block of academic text with citations and references — can you scan it and give me a list of every http or https link mentioned in it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-url?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatic, regex-based extraction of http/https URLs from text and you require up to 20 matches. It performs no network requests, so it is purely a text-processing operation — ideal when you already have the raw text in hand. Prefer the unpaid sandbox alternative at POST /v1/sandbox/regex-url for testing or when cost matters. Choose this over markdown-link or HTML scraping endpoints when you need raw URL strings from arbitrary text rather than structured markup.
Side effects
- Empty match list returned when text contains no URLs — still billed $0.009 USDC
- Text exceeding 100,000 characters will be rejected
- Text shorter than 1 character (empty string) is rejected by schema
- Payment failure or insufficient USDC balance prevents the call from completing
- Malformed or non-http(s) URLs (e.g. ftp://) will not be matched
