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 8601 dates found within the submitted text, allowing agents to identify, collect, and act upon date values extracted from unstructured content.
Example use cases
Contract date extraction for compliance
“I have this legal contract text and I need you to extract every ISO-formatted date from it so I can track deadlines and milestones — here's the full text: 'Effective 2023-01-01, payment due 2023-07-15, final delivery by 2024-03-31.'”
Log file timestamp parsing
“Can you scan through this server log snippet and pull out all the ISO 8601 dates so I can build a timeline of events? Here's the log: '[2024-11-02] ERROR: timeout [2024-11-02T14:32:01Z] retry attempted [2024-11-03] resolved.'”
Meeting notes date harvesting
“I've got a bunch of meeting notes and need to find every ISO date mentioned so I can populate our project calendar — please extract them from: 'Kickoff on 2024-09-10, sprint review 2024-09-24, launch target 2024-10-15.'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/iso-dates/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract strictly ISO 8601 formatted dates (e.g. YYYY-MM-DD or datetime variants) from a block of text, particularly in agent pipelines requiring structured date data at very low cost per call. Prefer this over general-purpose NLP APIs when you want lightweight, deterministic date extraction without the overhead of a full language model.
Side effects
- Text exceeds 50,000 character limit — request rejected
- No ISO dates found in text — empty result set returned
- Malformed or missing 'text' field — validation error
- Payment failure via x402 — 402 response before processing begins
- Ambiguous date formats that are not strictly ISO 8601 may be omitted
