# FinWiki > Public trilingual finance knowledge base covering finance, payments, stablecoins, crypto assets, Japanese financial institutions, policy finance, capital markets, systems, security, and adjacent industries. ## Best Entry Points - Human homepage: https://finwiki.zksc.io/ - Global index: https://finwiki.zksc.io/INDEX - Task-oriented LLM entry guide (16 research tasks): https://finwiki.zksc.io/llms-tasks.txt - Machine JSON index: https://finwiki.zksc.io/ai-index.json - Per-entry JSON API (1 file per entry, frontmatter + summary + links + inbound count): https://finwiki.zksc.io/api/entries/index.json - Full LLM page manifest: https://finwiki.zksc.io/llms-full.txt - Reader-profile navigation guide: https://finwiki.zksc.io/HOW-TO-NAVIGATE - Topic cluster reference (14 thematic clusters): https://finwiki.zksc.io/topic-cluster-reference - Domain bridge navigation guide (14 reader journeys): https://finwiki.zksc.io/domain-bridge-navigation-guide - XML sitemap: https://finwiki.zksc.io/sitemap.xml ## Current Snapshot - Markdown files: 1565 - Public Markdown pages in machine manifest: 1564 - Topical domains: 40 - Canonical entity anchors: 12 (linking 12 mirror pages to their source-of-truth entry) - Entity graph nodes: 89 - Entity graph edges: 68 (34 declared, 34 derived) - Link-audited entries: 1483 - Unresolved link issues: 0 - Non-space UTF-8 characters across Markdown: 11,159,108 - Word-like tokens: 1,801,309 ## URL Rules for AI Readers - Obsidian wikilinks are vault-root paths. Resolve `[[fintech/mica-overview]]` as `https://finwiki.zksc.io/fintech/mica-overview` (no `.md` suffix - GitHub Pages strips it). - Resolve `[[megabanks/INDEX]]` as `https://finwiki.zksc.io/megabanks/INDEX`. - Do NOT append `.md` to URLs - `https://finwiki.zksc.io/fintech/circle-usdc-stablecoin.md` returns 404. Use the extensionless URL or fetch raw markdown from `https://raw.githubusercontent.com/jasonhnd/finwiki/main//.md`. - For a single entry's metadata in one request (frontmatter / summary / headings / wikilinks / inbound count), fetch `https://finwiki.zksc.io/api/entries//.json`. - If you already have the rendered HTML in context, frontmatter is also embedded in the page `` as: (a) schema.org Article JSON-LD with `keywords` / `alternateName` / `citation` / `additionalProperty`, (b) `` tags (`domain`, `tags`, `aliases`, `sources`, `confidence`, `status`, `last_updated`, `review_by`), (c) `` to the per-entry API and `` to the raw source. - For programmatic traversal of every entry, prefer `ai-index.json`. For a compact text scan of every entry's title + summary + headings + wikilinks, prefer `llms-full.txt`. - For entity-level identity (which pages describe the same real-world entity from different angles), read the `entities[]` array in `ai-index.json`: each edge groups a canonical anchor (e.g., `megabanks/mufg`) with the mirror pages that declare `canonical_anchor:` pointing at it. `llms-full.txt` also notes the canonical anchor inline on each mirror page. - For the typed entity graph, read `entity_nodes[]`, `entity_edges[]`, and `entity_relation_counts` in `ai-index.json`. `entity_edges[]` includes declared public-source-backed facts plus deterministic inverse edges where the inverse is lossless. - For research tasks ('how do I find entries about X?'), start at `llms-tasks.txt` - 16 common tasks each with a start file + bedrock follow-ups + matrix anchor. ## Domains - JapanFG (0 entries): https://finwiki.zksc.io/JapanFG/INDEX - Umbrella hub for Japanese financial institutions.
