  "raw_analysis": "Axiora is a niche, developer-first platform that transforms Japan's official EDINET XBRL filings into structured, source-linked financial data, ownership time-series, and governance information. It serves 4,125 listed companies with 10 years of historical data, covering financial statements (JGAAP, IFRS, US GAAP), large-shareholding movements, and governance details. The platform positions itself as a focused alternative to broad enterprise terminals like Bloomberg and FactSet, emphasizing provenance and AI-agent accessibility. It offers a REST API with an OpenAPI spec, a Python SDK, and an MCP server with 41 read-only tools, enabling AI agents like Claude and ChatGPT to query financials with verifiable source links (doc_id). Key differentiators include source traceability (every row links to the EDINET filing), reproducibility (as_of tokens for bit-identical replay), and comprehensive entity resolution across Japanese scripts. The API appears to be production-ready, with free sign-up for a key and a subscription pricing model. It provides detailed documentation, quickstart guides, and comparison pages. The service is mature enough to have a public OpenAPI JSON, an MCP server, and a strong focus on developer experience and auditability. Integrations extend to AI agent frameworks (LangChain is mentioned in blogs), and it handles the archiving burden of EDINET's viewing window. The target audience includes AI agents, funds, developers, and data product builders requiring auditable Japanese disclosure data. Rate limits are not explicitly documented in the provided text, suggesting they may be defined in the full API docs. Overall, the platform is a well-structured, high-fidelity data infrastructure service specializing in Japanese corporate filings, with a strong emphasis on verifiability and AI-readiness."
