Changelog

Every dataset release, dated and versioned. The API reports its version in every response as data_version.

2026-08-28

Ingestion agent: POST /api/v1/ingest and MCP tool ingest_text turn unstructured financial text into FF-Schema entities and relationships (Workers AI extraction + strict validation: sector/asset taxonomies, relationship types, ISIN checksums, LEI/MIC formats; unresolved identifiers reported, never invented).
Read-only by design: extracted output is returned to the caller and is never written into the Finance Foundation dataset. Fair use: 20 requests/day per IP, 6000-char input limit.

2026-08-28

Sponsor-a-dataset path on /data: support funds dataset depth and upkeep, credited with attribution — access is never gated. Free tier and the open MCP server stay full; paid tiers remain roadmap, to be built only on sustained API/MCP usage growth.

2026-08-28

Research note #7, 'The Concentration Graph' — the first of a monthly cadence, computed from the site's own dataset (country/company/fund-overlap concentration + the identifier-gap finding).
RSS feed at /rss.xml for research notes; <link rel=alternate> on every page.

2026-08-28

New relationship types: member_of (index membership — covered subset per index: S&P 500, Nasdaq-100, DAX, EURO STOXX 50, FTSE 100, Nikkei 225, Hang Seng, CSI 300) and holds (top fund holdings among covered entities, approximate).
Interactive knowledge-graph map at /graph — every entity and edge, canvas-rendered, click-through to entity pages.
GET /api/v1/graph/full — the entire graph in one payload; neighborhood graphs and the MCP graph tool now include the new edges.

2026-08-28

Native MCP server at /mcp (Model Context Protocol, Streamable HTTP, stateless, no auth) — six tools: lookup, list, search, resolve_identifier, graph, live_data.
Connect from Claude Code: claude mcp add --transport http finance https://finance.foundation/mcp — or as a custom connector in Claude.ai/Desktop.

2026-08-28

First live data layer: 12 daily-updated series (BTC/ETH/SOL/USDT/USDC prices, EUR/USD·USD/JPY·GBP/USD·USD/CNY, ECB main refinancing rate, US 10Y Treasury yield, US CPI YoY) from keyless open sources (CoinGecko, ECB, US Treasury, OECD), stored in D1 with per-observation provenance.
New: GET /api/v1/live; live blocks on matching asset pages and /economy cards — labeled 'daily reference, not real-time'.
Euro-area HICP deliberately deferred: Eurostat/ECB discontinued the ICP dataset in Feb 2026; will attach the successor dataset when published.

2026-08-28

Coverage expansion: 121 companies (was 34), 20 markets (+Shenzhen, ASX, B3, BME, Borsa Italiana, Nasdaq Stockholm, BSE), 21 countries, 30 assets, 25 funds, 20 banks.
Identifiers extended: LEI 119/121 (Chevron and Kweichow Moutai unverifiable — left null), ISIN 108/121 (check digit validated), FIGI 107/121 (name cross-checked).
Cross-site knowledge graph: bank entities now link their infrastructure profile on banking.foundation.
Datasets drafted by a 7-agent workflow and adversarially fact-checked before release (1 fix, 6 wording corrections applied).

2026-08-28

External identifiers for all companies: LEI (GLEIF, hand-audited), ISIN (check digit validated, 33/34 — BlackRock ISIN deliberately null pending post-reorg verification), share-class FIGI (OpenFIGI, name cross-checked).
New: /identifiers resolver page and GET /api/v1/resolve?q= endpoint.
New: OpenAPI 3.1 specification at /api/v1/openapi.json.
