Machine-readable settlement service
Output
Returns a structured object containing the list of URLs found within the input text, extracted as discrete string values.
Example use cases
Extract links from newsletter content
“I have a newsletter body pasted here — can you find every URL mentioned in it? 'This week: OpenAI launches new model https://openai.com/news, Meta updates policy https://meta.com/policy, and a great read at https://techcrunch.com/article/ai-roundup'.”
Parse URLs from scraped HTML text
“I scraped the plain text from a webpage and need you to pull out all the links embedded in it — here's the text: 'Visit our docs at https://docs.myapp.io or reach support at https://support.myapp.io/tickets and download the SDK from https://github.com/myapp/sdk'.”
Identify links in user-submitted comment
“A user submitted this comment and I want to know every URL they included before I moderate it: 'Great site! You should also check https://spammysite.biz and https://malware.example.com for more info.'”
