Axiora

Axiora is now live on the @openbb_finance App Marketplace. Verifiable ownership and capital intelligence for Japanese equities — every row traced to an EDINET filing. Built for Japan equity analysts at hedge funds and research platforms. Start exploring → pro.openbb.co

Built for foreign funds, equity research, M&A advisory, compliance teams — anyone asking questions about Japanese companies without reading Japanese. Sign up to get notified at launch.

Ask "who is accumulating Toyota shares?" and get a cited answer in seconds. Not from training data. From every regulatory filing Japan has published. Introducing the Axiora analysis engine. Every number, provably right. Coming soon. axiora.dev/architecture

The engine routes your question, resolves the company, runs domain-specific skills and synthesizes a cited answer. Two AI calls. Everything between them is deterministic.

“Claude with a PDF” wins when the task is answering one question once. It loses when you need the answer to be traceable, repeatable, and correct across thousands of companies and filings. That’s the gap between a useful output and a data product.

The real competitor in Japanese financial data in 2026 isn't Bloomberg. It's Claude with a PDF. The quality is good enough to feel trustworthy. That's exactly what makes it dangerous. We wrote about the line between "probably right" and "provably right": axiora.dev/en/blog/why-gr…

We’re rebuilding Axiora’s API around a stricter standard. A more robust architecture.

“Trust us” is not a good enough interface for financial data. Not for humans. Definitely not for AI. We already had the API. What changed is the standard: every number should be verifiable, not just correct.

@TheLongHappy @ChesleyCapital We are also looking for beta testers for Axiora platform A complete UI dashboard to track exactly this and more

@TheLongHappy @ChesleyCapital @ChesleyCapital We’ve structured the filings into queryable ownership timelines with amendment tracking, holder normalization, and MCP/API access. axiora.dev/en/docs/mcp

@nororororororor CSMARみたいに、研究でそのまま使えるレベルまで構造化されたデータは日本だとまだ少ないですよね。 もしあれば、どのあたりのデータが一番欲しいですか？（財務、株主構成、時系列など）

最近edinetパースするAPI(MCP)サービス増えてきたな(儲かるのだろうか) 個人的にはCSMARのとか作って欲しい

We built exactly this. Axiora tracks every 大量保有報告書 (large shareholding report) filed on EDINET — 19,000+ holdings across 1,300+ investor-company pairs with accumulation/exit trajectories, activist signals, and cross-holding maps. Think WhaleWisdom but for Japan's 5% disclosure system. API + Claude MCP: axiora.dev

@InvestInJapan Quick question - is there anything similar to whalewisdom that helps you track which investor owns which companies? I know edinet annual securities report show list for individual companies…

🪛Japan Research Toolkit 2025 🔧 Since you may have missed it over the holiday period: I’ve updated my Japan Research Toolkit! I think Japan remains a huge investment opportunity despite the run the last couple years but look, I know it can sometimes be difficult to research companies as a foreigner. This is my list of resources I use that can mostly be translated English and I hope this can help your scuttlebutting/idea generation. It’s a living list that will evolve over time. You will always be able to find it under the “useful resources” section of my site for free. ☀️ For your convenience you can also find the list below, but without the hyperlink since X would send me to the shadow realm otherwise. Don't forget to bookmark it and share it with others who might find this useful!

@pJTi8OAZ2HyWTOe Axioraという金融データAPIを作っていて、TDNet決算短信のパース済みデータをAPIとMCPで提供しています。Claude Codeからそのまま使えます。 もしよければ試してみてください。 axiora.dev/ja

EDINET APIじゃ適時開示をリアルタイムで取得できないという事実に気付いた、、結局J-Quants APIから18:00の速報財務情報とTDnetのタイトルをスキャンして、モメンタム候補を通知してもらうくらいしか思い浮かばなかった。とりあえずその修正をclaude codeでかけた

ありがとうございます。まさにその通りで、EDINETの情報は価値があるのに、開発者向けに扱いやすい形にするところまで手が回っていないことが多いです。 Axiora は、そこを API として使える形にして、調査・分析・プロダクト開発にそのまま組み込めるようにしています。まだ知られていないのは課題ですが、必要な人には確実に刺さる領域だと思っています。

この人結構コミュニティに有用なことやってると思うんだけど、話題になってないのは何故だろう。 axiora.dev/ja/blog/edinet…

Financial data retrieval was slower through MCP than our direct endpoint. We fixed it. Latency down 73% on MCP. Same queries. Now roughly in line with the endpoint.

@Cryptinflux DM us your email and details and we'll set you up with Pro access.

@axioradev Financial time-series endpoints + MCP for Claude is a combination I have been looking for. 31-tool surface area is broad enough to build real analysis workflows.

Japanese financial data is hard to get. EDINET filings are in XBRL. Ownership reports are PDF-only. Financials for 4,125 companies are scattered across regulatory databases in Japanese. We structured all of it into an API. If you're a startup building with this data, we'll give you full access free for 60 days: axiora.dev/en/startup

We built this because the alternative is manually downloading XBRL from EDINET, parsing it, resolving entity names, and praying. Ask us how we know.

Genuine question for Japan equity analysts: how do you track ownership changes between quarterly snapshots? Because the actual filings show moves happening in single-digit days that don't appear anywhere else.
