How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the ISO-formatted dates found in the input text, suitable for downstream date processing, calendar integration, or structured data pipelines.
Example use cases
Contract deadline extraction
“Here's a vendor contract — can you extract every date mentioned and give them back to me as ISO 8601 dates? 'The agreement commences January 10, 2025, with quarterly reviews on April 10, July 10, and October 10, and expires December 31, 2025.'”
Meeting notes date parsing
“I have these meeting notes and need all the dates pulled out in ISO format so I can add them to my calendar: 'We agreed to follow up next Tuesday the 22nd, with a full review by end of Q2, June 30th.'”
News article timeline building
“Extract all the ISO dates from this news article so I can build a timeline: 'The company was founded in February 2018, went public on November 3, 2021, and announced layoffs in early March 2024.'”
