How this service works
Binary SEC change signal since a date: changed true or false, filing count, form types and the latest official EDGAR filing.
Output
A structured response indicating whether any SEC filings have been made since the specified date (changed: true/false), the total count of new filings, the distinct form types submitted (e.g. 10-K, 8-K, 4), and metadata about the most recent official EDGAR filing including form type, filing date, and accession number.
Example use cases
Earnings season filing alert
“Did Tesla file anything new with the SEC since January 1st? I need a simple yes or no, plus how many filings and what form types were submitted.”
M&A due diligence check
“Before we proceed with this acquisition, can you check if CIK 0000320193 has had any SEC filing activity in the past 30 days — give me a changed signal, form list, and the most recent EDGAR filing.”
Automated portfolio monitoring
“For my watchlist — can you check if Microsoft has any new SEC filings in the last 7 days and flag it as changed or not changed so I can decide if I need to dig deeper?”
Technical details
Endpoint
GEThttps://x402-data-api.x402agent.workers.dev/sec-change-signal?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, lightweight boolean signal about whether a company has new SEC activity — ideal for triggering downstream workflows, portfolio monitors, or alert systems without pulling full filing content. Prefer this over vellum-filing-delta when you only need a yes/no changed flag rather than detailed financial fact deltas, and over vellum-sec-latest when you need to check across a date window rather than fetching a single most-recent filing.
Side effects
- Unknown ticker symbol returns an error or empty result
- Invalid CIK format causes a 400-level response
- If neither ticker nor CIK is supplied, the request fails validation
- Future or unparseable 'since' date may cause an error
- Company with no recent filings returns changed: false with count 0
- Rate limits or EDGAR downtime may cause upstream failures
