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 extracted ISO-format dates found in the input text, likely as an array of date strings (e.g. '2024-03-05', '2025-01-01') identified by the T5 model from natural language date expressions.
Example use cases
Contract date extraction
“I need all the dates from this legal agreement pulled out and normalized to ISO format — here's the text: 'This contract commences on the fifteenth of April, 2024 and the initial term ends June 30th, 2024, with automatic renewal on January 1, 2025.'”
News article timeline builder
“Can you find every date mentioned in this news article and return them as ISO dates? The article starts: 'The project was announced on February 3rd, broke ground in mid-March 2023, and is expected to complete by Q4 2024.'”
Log file date normalization
“I have a messy server log with mixed date formats — can you extract all the dates and give them back to me as ISO strings? The log text is: 'Error on Jan 7 2024 at 14:32, warning logged March 3rd, system reboot scheduled for the 15th of next month.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/iso-dates/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, low-cost date extraction from unstructured text and want a per-call pay-as-you-go model via x402 on Base. Ideal for agents processing documents, emails, contracts, or articles where dates need to be normalized to ISO format without spinning up a full NLP pipeline. Best suited for single-document or per-call workflows rather than large batch jobs.
Side effects
- Text exceeds 50,000 character limit — request rejected
- No recognizable date expressions found in text — empty result returned
- Ambiguous dates (e.g. '05/06/07') may be misinterpreted or omitted
- Payment failure via x402 results in 402 response before processing
- Malformed or non-UTF8 text may cause parsing errors
