How this service works
Call when an agent needs ISO week dates extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/regex-iso-week first.
Output
Returns a list of up to 20 ISO week date strings matched in the input text (e.g. ['2024-W03-1', '2024-W04-5']). An empty list is returned if no matches are found, and the call is still billed in that case.
Example use cases
Sprint timeline extraction from notes
“I have these project notes with week references all mixed in — can you pull out every ISO week date like 2024-W12-1 from this text? Here's the content: 'Sprint 1 started 2024-W10-1, sprint 2 on 2024-W12-1, demo on 2024-W13-5.'”
Audit log week date scanning
“Can you scan this audit log entry and tell me every ISO week date you find in it? The text is: 'Changes approved 2023-W45-3, deployed 2023-W45-5, rollback flagged 2023-W46-1.'”
Calendar reference parsing from emails
“I've got a bulk email body that mentions multiple week dates in ISO format — please extract all of them from this text: 'Kickoff is 2025-W02-1, mid-review 2025-W05-3, final delivery 2025-W08-5, retrospective 2025-W09-2.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-iso-week?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to reliably extract ISO 8601 week date strings (YYYY-Www-D format) from arbitrary text and are willing to pay $0.004 USDC per call. If cost is a concern and you have access to the free sandbox version (POST /v1/sandbox/regex-iso-week), prefer that first. Choose this over manual regex when working within an agent pipeline that needs structured match results without executing local code.
Side effects
- Empty match list returned if no ISO week dates exist in the text — still billed $0.004 USDC
- Input text exceeding 100,000 characters will be rejected with a validation error
- Malformed or missing 'text' field returns a 400 error
- Matches are capped at 20; additional occurrences beyond 20 are silently truncated
