Japan EDINET Insider Filings — インサイダー取引 API

Japan EDINET Insider Filings

Japan EDINET Insider Filings is a NexGenData tool on Apify that returns 5% rule, change and buyback filings with optional holdings % from the FSA EDINET API.

🔑 First: get your free EDINET API key (a few minutes)

This actor reads the Japan FSA's EDINET API v2, which answers only with an API key. The key is free and shown as soon as you finish signing up.

1. Create an account: open https://disclosure2.edinet-fsa.go.jp/, choose EDINET API → register (or Log in), and sign up with your email address (a code is emailed to you) and a password.
2. Confirm your phone: EDINET requires a phone check by SMS code or automated call.
3. Get the key: enter a contact name and phone on the API key screen; the key appears at once. Paste it into the EDINET API key field, the first field in the input form, and start the run.

No key: Apify won't start the run (the field is required), so nothing runs and nothing is charged. EDINET's step-by-step guide is section 2-3 of its API specification: https://disclosure2dl.edinet-fsa.go.jp/guide/static/disclosure/download/ESE140206.pdf.

Track Japan EDINET insider and large-shareholder filings. Built for analysts, quants, fintech builders and AI agents.

🧾 JSON sample record

One real record from run 6aFcrccDAik2GdgUO (emails/phones masked, long text shortened):

{
  "_type": "auth_missing",
  "_blocked": true,
  "error": "edinet_api_key_required",
  "message": "Japan FSA EDINET API v2 requires a free subscription key. Register at https://disclosure2.edinet-fsa.go.jp/ (email + phone check, no credit card). Pass via input field `apiKey` or set the `EDINET_API_KEY` environment variable on the actor task. Rate limit: ~3 requests/second per key.",

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.005	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
EDINET filing (edinet-filing)	$0.1	Per Japan EDINET insider transaction filing extracted

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.1 = $10.00 plus the start fee.
