Broader coverage than the snapshot route. **Note:** `change` / `changePercent` here are **intraday** (close minus open of the latest bar), not the close-to-close daily move — use `change1d` from `/openapi/v1/market/indices/snapshot` for the daily change. ## OpenAPI ````yaml /openapi.yaml get /openapi/v1/market/global-indices openapi: 3.1.0 info: title: HayInsights Open API version: 0.1.0 description: > Programmatic access to the **HayInsights** financial-data hub — commodities, crypto, ETF, FX, macroeconomic, real-estate, news, economic-calendar and market-index datasets, served from a single API surface under `/openapi/v1/*`. This specification is the **single source of truth** for the public API surface — shared by SDK codegen, the reference docs, and (later) the mock server / contract tests. ## Authentication Every request must carry your API key in the `X-API-Key` header. There is a single authentication tier — no request signing. Create and manage keys in the HayInsights dashboard (Account → API keys). See **Authentication**. ## Plans & quota Access to each data domain and your request quota are governed by the subscription plan attached to your key. Each endpoint consumes a **weighted** amount of your per-minute quota; every response carries `X-RateLimit-*` headers. See **Rate limits** and **Plans & features**. contact: {} servers: - url: https://api-v2.hayinsights.com description: Production security: - HayInsightsApiKey: [] tags: - name: Commodities description: >- Spot prices, top movers, gold–DXY correlation and historical series for energy, metals and agricultural commodities. - name: Crypto description: >- Crypto market overview, dominance, bubble map, on-chain and derivatives metrics. - name: ETF description: >- Exchange-traded fund listings, performance & net-flow rankings, heatmap, holdings, NAV growth and fund composition. - name: FX description: >- Foreign-exchange summary, live table, 90-day correlation matrix and the emerging-market stress monitor. - name: Macro description: >- Macroeconomic indicators — GDP, CPI/PCE, exchange rates, population, central-government debt and policy rates / bond yields. - name: Real Estate description: >- Land prices, transaction-level records, administrative geography (provinces / wards) and choropleth GeoJSON, by country. - name: News description: >- Market news headlines with per-article sentiment, plus an aggregate sentiment reading over a rolling window. - name: Calendar description: >- Economic calendar — rate decisions, CPI and GDP releases, market holidays and asset-level events. - name: Market description: >- Index snapshots and global index closes — levels and daily moves for S&P 500, Nasdaq, Nikkei, VN-Index and others. paths: /openapi/v1/market/global-indices: get: tags: - Market summary: Global indices description: > Latest close for all tracked global indices, including South-East Asia.
