List all the justices and open a justice's profile (dates, places, seats held). Live data straight from oyez.org, the definitive multimedia archive of the Supreme Court. Distinct, authoritative civic data — ideal for legal-tech, research, education, news and civic apps. 5 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

 Sweden Municipal Statistics API — oanor API marketplace

Sweden Municipal Statistics API

Swedish municipal and regional statistics straight from Kolada — the open database run by the Council for the Promotion of Municipal Analyses (RKA) — no key, read live. Kolada holds roughly 6,000 key performance indicators tracking the finances and service quality of all 290 Swedish municipalities and 21 regions: personnel costs, school results, elderly care, waiting times, environment, demographics and much more. The kpis endpoint lists and searches the indicator catalogue by title. The kpi endpoint returns the full metadata of a single indicator (its definition, operating area and source). The municipalities endpoint lists every municipality and region with its official code. The data endpoint returns a chosen indicator's full annual value series for a given municipality, with the latest value highlighted. The meta endpoint documents the API. Live data from Kolada v3, lightly cached. Live. 5 endpoints. This serves Swedish public-sector statistics; for the krona exchange rate or national CPI use an FX / national-statistics API.

 US Federal Fiscal API — oanor API marketplace

US Federal Fiscal API

Live US federal fiscal data from the US Treasury's official FiscalData API — the cost-and-flow side of US public finance. Get the federal budget deficit or surplus by month for the current fiscal year (receipts, outlays and the net) from the Monthly Treasury Statement; the interest the United States pays to service its national debt, by month and fiscal-year-to-date, broken down by security type; and the average interest rate the Treasury pays on each class of its debt (Bills, Notes, Bonds, TIPS) plus the weighted overall rate. Live, no key, nothing cached. Distinct from debt-level (debt-to-the-penny) and auction feeds — this is the deficit, the interest bill and the average rate on the debt.
