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 minutes after they hit EDGAR.

Start free trial 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 five minutes during earnings season, hourly between cycles. Used by analysts, journalists, retail investors, and compliance teams who need to know about a filing before it shows up in the headlines.

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, a watchlist of 50, or a sector via the EDGAR full-text search URL.

Five-minute check intervals

Earnings 8-Ks often move stock prices in seconds. A five-minute interval gives you a few minutes' lead time before the news desk picks it up.

Webhook integration

Pipe alerts into Slack, Discord, a trading dashboard, or a custom risk system. The webhook payload includes the filing type, the company, and the EDGAR URL.

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

Five-minute checks during earnings season; hourly between.

Receive alerts

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

Common use cases

Catch earnings 8-Ks minutes after they post
Track insider buying and selling via Form 4 filings

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 at five-minute intervals and supports webhook delivery to Slack, Discord, or any custom system. For analyst teams, the webhook + speed 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 typically 5–6 minutes on a five-minute check interval. Faster intervals are available on enterprise plans.
