How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the ISO-formatted dates extracted from the input text, likely as an array of date strings (e.g. YYYY-MM-DD) identified from natural language expressions in the provided text.
Example use cases
Contract date extraction for legal review
“I have this contract clause and need all the dates extracted in ISO format: 'Payments are due on the first of each month starting February 1, 2024, with a final payment no later than November 30, 2025.' Can you pull those out for me?”
Meeting notes timeline parsing
“Here are my meeting notes from last week — can you find all the dates mentioned and return them as ISO dates? 'We agreed to deliver the prototype by mid-March, with a client demo scheduled for April 4th and final sign-off expected before June 2024.'”
News article date harvesting
“I've got a long news article and need every date reference extracted as an ISO date. The article starts: 'On September 11, 2001, events unfolded... by October 7, 2001 the response had begun... a decade later, on May 2, 2011...' — go ahead and pull them all out.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/iso-dates/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call ISO date extraction from unstructured text without standing up your own NLP pipeline. It is ideal for agents processing contracts, emails, reports, or articles where dates must be normalized to ISO format programmatically. At $0.018 USDC per call it is cost-effective for moderate volume. Prefer a local NLP library if you need to process thousands of documents per minute or require multilingual date support.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- No recognizable dates found in text — empty or null result returned
- Ambiguous date formats (e.g. '05/06/07') may be misinterpreted or skipped
- Non-English date expressions may not be recognized
- Payment failure via x402 protocol — 402 response, no extraction performed
- Malformed JSON request body — 400 error
