About
AutonoMath is a REST and MCP API that exposes Japanese public-program data — subsidies, loans, tax incentives, and certifications — to AI agents in a single call. 6,771 programs are normalized from primary sources (METI, MAFF, SME Agency, Japan Finance Corporation), scored into tiers (S/A/B/C/X), cross-linked with 22+ exclusion rules, searchable via FTS5 trigram over Japanese text, and every row carries source_url and fetched_at for lineage.
Why it exists
jGrants is Japan's application portal. It is not a discovery or compatibility layer. Asking "which subsidy matches this business, and which of them can be combined?" still requires a human to browse ministry sites, download PDFs, cross-reference notice documents, and keep up with ad-hoc revisions. AutonoMath is that missing layer, packaged as an API that AI agents can actually call. MCP protocol version 2025-06-18; no SDK required.
Who built it
Built and maintained solo by Shigetoshi Umeda (梅田茂利), independent developer. Hosted on Fly.io Tokyo (nrt). Billed via Stripe Tax with Japanese invoice-system (インボイス) compliance once the registration number is assigned.
