SEC 8-K Event Monitor — Material Filing Alerts

Monitor recent SEC 8-K filings and receive alerts when new material events appear. This Actor watches issuers or event types, tags each filing by 8-K item code, snapshots seen accession numbers, and emits only new filings in delta mode.

What it does

On each run it pulls recent 8-K filings using NexGenData's owned sec-form-8k-material-events-scraper, tags each filing by 8-K item code and a plain-English event label, records the accession numbers it has seen, and in delta mode emits only filings that are new since the last run. Schedule it and you only ever see new filings. It monitors recent filings on a rolling window — it is not a full real-time institutional feed, and it does not provide investment advice.

Who it's for

Equity research, investor relations, credit and counterparty risk, event-driven funds, and corporate-development teams that want a lightweight recurring 8-K watch.

Recommended setup

Run once in full mode to baseline, then schedule daily delta runs. The first delta run per watch query records a baseline and emits nothing (expected); after that you get only new filings.

Inputs

Field	Default	Notes
tickers	[]	Only alert on these issuer tickers; empty = all issuers in the window
item_codes	[]	Only alert on these 8-K item codes; empty = all events
lookback_days	3	How many days back to scan each run
mode	delta	delta (new only) or full (all in window)
max_filings	500	Safety cap per run
include_raw	false	Attach the raw source filing record

Common item codes: 1.01 material agreement (M&A/contract), 1.05 cybersecurity incident, 2.01 acquisition completed, 2.02 earnings, 4.01 auditor change, 4.02 restatement / non-reliance, 5.02 officer or director change.

Outputs

accession_number, change_type, cik, ticker, company, form, filing_date, period_ending, items, event_labels, event_descriptions, state, sic, filing_url, matched_watch, detected_at (plus raw when include_raw is true). event_labels is the plain-English label for each 8-K items code.

Delta mode vs full mode

• full — emits every filing in the window (each tagged) and records the snapshot.
• delta — emits only filings whose accession number has not been seen before for this watch query. The first delta run records a baseline and emits nothing; later runs emit only new filings.

Event labels

Each 8-K item code is mapped to a readable label (e.g. 4.01 → "Change in auditor", 4.02 → "Non-reliance / restatement", 1.01 → "Material agreement (M&A/contract)", 5.02 → "Officer/director departure or election", 1.05 → "Cybersecurity incident").

Limitations

This is an alerting tool, not investment or legal advice. It monitors recent 8-K filings on a rolling window via the owned source Actor; it is not a full real-time institutional coverage feed. Coverage and timing follow SEC EDGAR's publication of 8-K filings. Always confirm against the official filing before acting.
