How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing structured mention data extracted from the input text — typically including the identified mentions, their positions or context within the text, and associated metadata about each referenced entity or term.
Example use cases
Social media mention mining
“I have a 5000-character scraped social post thread — can you pull out all the mentions in it so I can see who and what is being referenced?”
News article entity extraction
“Here's the full text of a news article about the tech industry — extract every mention from it so I can build a knowledge graph of what's discussed.”
Contract reference detection
“I need you to go through this contract text and extract every mention of parties, clauses, or entities referenced in the document.”
