How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing an array or structured list of extracted ISO-formatted dates (e.g. YYYY-MM-DD) identified within the submitted text, preserving order of appearance where possible.
Example use cases
Contract deadline extraction
“I have this contract text — can you extract all the dates from it and give them back as ISO dates so I can load them into our calendar system? Here it is: 'The agreement commences on the first of January 2025, with quarterly reviews on April 1st, July 1st, and October 1st, and expires December 31, 2025.'”
Log file date normalization
“I've got a block of server log entries with dates written all over the place — things like 'Jan 3rd', '2024/02/14', 'March the 9th' — can you extract and normalize all of them to ISO format so I can sort them properly?”
News article event timeline
“Extract all the dates mentioned in this news article so I can build a timeline of events — I need them as ISO dates: 'Talks began in early February 2023, broke down by the 14th, resumed on March 2nd, and a final agreement was signed on the 30th of April.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/iso-dates/t6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract and normalize dates from free-form or semi-structured text into ISO format, especially in automated agent pipelines where consistent date formatting is critical. It is ideal for processing contracts, emails, logs, articles, or any unstructured document where dates appear in mixed or natural language formats. At $0.004 per call with pay-per-use x402 billing on Base, it suits high-volume agent workflows without subscription overhead.
Side effects
- Text exceeds 50,000 character limit — request rejected
- No dates found in text — returns empty result set
- Ambiguous date formats (e.g. '01/02/03') may be parsed incorrectly or omitted
- Payment failure via x402 on Base — call not executed
- Malformed input JSON with missing 'text' field — validation error
