How this service works

Paid x402 API that extracts important deadlines from public webpages for agents and automated workflows.

Output

Returns a JSON object with a plain-language summary, a list of deadlines each containing date, time, label, timezone, and verbatim evidence text from the page, a confidence score (0-1), the checked timestamp, and a boolean indicating whether deadlines were found.

Example use cases

Grant application deadline monitoring

“Check this grant opportunity page and tell me the exact deadline — date, time, and timezone — so I can add it to my calendar: https://example.com/grant-call”

Job posting closing date extraction

“I'm tracking job applications — can you look at this job listing and extract the application deadline from the page? https://example.com/job-posting”

RFP submission deadline detection

“We just received this RFP link and need to know when submissions are due. Can you pull out the deadline from the page? https://example.com/rfp-2026”

When to prefer

Choose this endpoint when you need structured, machine-readable deadline data extracted automatically from a public webpage without manual parsing. It is ideal for agents monitoring grant portals, job boards, RFP pages, or academic admissions sites where deadlines are embedded in prose. Prefer it over general-purpose web scrapers when you specifically need deadline/date extraction with confidence scoring and timezone awareness.

Side effects

URL is not publicly accessible (returns error or empty result)
Page content is behind a login wall and deadlines cannot be read
No deadlines found on the page (deadlines_found: false, empty deadlines array)
Ambiguous or relative date references (e.g. 'next Monday') may lower confidence score
Page uses non-standard date formats that reduce extraction accuracy
Network timeout or unreachable URL
