FILING EVENTS API · v1

Stop parsing EDGAR.
Get structured filing events in real time.

Register a rule once. The moment an 8-K, Form 4 (insider), or S-3 (dilution) hits SEC EDGAR for the tickers and forms you care about, we push you a clean, ticker-mapped, item-coded JSON event — by webhook or poll. No XML. No scraping. No maintenance.

Why

1 · Get a key

Free tier, self-serve. Save the key — it is shown only once.

curl -X POST https://catalystedgescanner.com/api/v1/filing/signup \
  -H "Content-Type: application/json" \
  -d '{"email":"[email protected]"}'

# → {"api_key":"ce_F_...", "tier":"filing", ...}

2 · Register a rule

Match by form, ticker, or both. Add a webhook_url (https) to get pushed events, or omit it and poll.

# Every insider Form 4 for NVDA → your webhook
curl -X POST https://catalystedgescanner.com/api/v1/filing/rules \
  -H "X-API-Key: ce_F_..." -H "Content-Type: application/json" \
  -d '{"form":"4","ticker":"NVDA","webhook_url":"https://your.app/hook"}'

# Every 8-K, any ticker (poll mode — no webhook)
curl -X POST https://catalystedgescanner.com/api/v1/filing/rules \
  -H "X-API-Key: ce_F_..." -H "Content-Type: application/json" \
  -d '{"form":"8-K"}'

Manage rules: GET /api/v1/filing/rules · DELETE /api/v1/filing/rules/{id}

3 · Receive events

    "form": "4",
    "form_label": "Insider transaction (Form 4)",
    "filed_utc": "2026-06-26T17:46:26-04:00",

}
