SEC filing alerts and EDGAR monitoring

Track new filings for any public company. Catch 10-Ks, 10-Qs, 8-Ks, 13F-HR position disclosures, and S-1 IPO filings without refreshing EDGAR yourself.

Start free How it works

WebMonitor.fyi watches the SEC EDGAR system and company filing pages for new submissions. The SEC filing alerts fire on the schedule you pick — every 30 minutes during earnings season, six-hourly or daily between cycles. Built for analysts, journalists, retail investors, and compliance teams who want to know about a filing without watching the feed all day.

What it does

Filing-type filtering

Watch any combination of 10-K, 10-Q, 8-K, 13F-HR, S-1, Form 4 (insider transactions), Form 144, and proxy filings. Write the criterion to alert on only what matters.

Company-specific or sector-wide monitoring

Track a single ticker via its EDGAR filings index, or a whole sector via an EDGAR full-text search URL — each monitor watches one page you choose.

30-minute check intervals

On the Pro plan, checks run as often as every 30 minutes — so you hear about a new filing within half an hour of it posting, without refreshing EDGAR yourself.

Webhook integration

Pipe alerts into Slack or any system that accepts a JSON POST — a trading dashboard or a custom risk tool. Each alert carries an AI summary of the new filing activity and a link back to the page.

How to set it up

Find the EDGAR URL

For a single company: the EDGAR filings index for that CIK. For a sector or filing type: an EDGAR full-text search URL with your filters applied.

Set the criterion

Examples: "Alert me on any new 8-K from this company." "Notify me when any Form 4 is filed by an insider at companies in my watchlist." "Let me know when a new S-1 is filed by any company in the SaaS sector."

Pick a frequency

30-minute checks (Pro) during earnings season; six-hour or daily between.

Receive alerts

Webhook into Slack is the standard for analyst teams. Email for individual investors.

Common use cases

Catch earnings 8-Ks within half an hour of posting
Track insider buying and selling via Form 4 filings
Monitor 13F-HR releases for fund position changes
Watch for new S-1 filings in a sector you cover
Catch material event 8-Ks (acquisitions, executive departures, restatements)
Track regulatory comment letters and enforcement filings

Honest limits

WebMonitor reads EDGAR's public filing index — the source of truth for SEC filings. We don't aggregate, summarize, or interpret the filing content; that's the analyst's job. For very high-frequency trading use cases (millisecond-grade), specialized direct EDGAR feeds beat web monitoring.

Frequently asked questions

How does this compare to EDGAR's own email alerts?

EDGAR's built-in email alerts are limited to specific filings and a roughly daily cadence. WebMonitor checks as often as every 30 minutes and supports webhook delivery to Slack or any system that accepts a JSON POST. For analyst teams, the webhook + cadence combination is the main upgrade.

Can I track Form 4 insider transactions?

Yes. Form 4 is one of the filing types you can filter on. Set up one monitor per company or one monitor against a full-text search URL covering all companies on your watchlist.

Does it work for non-US filings (SEDAR, FCA)?

WebMonitor watches any publicly accessible filing portal — SEDAR for Canadian filings and the FCA National Storage Mechanism for UK filings both work the same way. Paste the filing index URL and write the criterion.

Is this useful for retail investors or only institutions?

Both. Retail investors use it for portfolio-level alerts and earnings tracking. Institutions use it for sector-wide coverage, insider monitoring, and webhook integration into existing analyst tooling.

How fast are the alerts?

From the filing appearing on EDGAR to the alert arriving in your channel is at most one check interval — about 30 minutes on the Pro plan's fastest cadence. For sub-minute needs, a direct EDGAR feed is the right tool.
