Cap rate and NOI
API · /realestate-api
Real Estate Investment API
Real-estate investment maths as an API, computed locally and deterministically — the property-analysis layer a loan calculator leaves out. The cap-rate endpoint gives the net operating income and capitalization rate of a rental from its price, gross rent, vacancy allowance and operating expenses (NOI = gross rent × (1 − vacancy) − expenses; cap rate = NOI / price), plus the gross rent multiplier — the unlevered view a buyer compares deals on. The cash-flow endpoint adds financing: from a down payment (amount or percent), interest rate and term it amortizes the mortgage, then returns the monthly payment, annual debt service, the property cash flow, the cash-on-cash return (annual cash flow ÷ cash invested), the debt-service-coverage ratio (DSCR = NOI ÷ debt service, the figure lenders underwrite to) and the loan-to-value. The metrics endpoint runs the quick screening ratios investors filter on — the 1 % rule (monthly rent ≥ 1 % of price), gross rental yield, gross rent multiplier and price per square foot. Money in, ratios out, in one consistent currency. Everything is computed locally and deterministically, so it is instant and private. Ideal for proptech, real-estate-investment, rental-analysis and landlord app developers, deal-screening and underwriting tools, and personal-finance dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. This is property-investment analysis; for pure loan amortization use a loan API and for DCF/NPV use an investment-appraisal API.

Residential Property Prices API
How house prices are moving across the world's economies, read live from the Bank for International Settlements' Selected Residential Property Prices dataset. For roughly 60 countries the BIS publishes a quarterly residential property price index — both nominal and real (inflation-adjusted) — together with its year-on-year change. The latest endpoint returns every country's most recent reading at once — the nominal and real index plus the nominal and real year-on-year growth — sortable by nominal or real YoY so you instantly see which housing markets are heating up and which are cooling once you strip out inflation. The country endpoint returns a single country's latest reading; the history endpoint returns its quarterly index time series (nominal and real) so you can chart a market over time. Countries are given as ISO-2 codes (US, DE, GB, JP) or common names (xm is the euro area). The nominal index is the headline price level; the real index is deflated by consumer prices, so a negative real YoY means prices are falling after inflation even when the nominal index still rises. This is the real-estate / property-price macro data-cut — distinct from the FX-rate, central-bank, yield-curve, commodity and equity-index APIs in the catalogue. Live source, no key required upstream, nothing stored.

Programming Languages API
The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.

MIME Types API
Die kanonische MIME-/Medientyp-Datenbank (die jshttp mime-db, die von Express und dem Großteil des Node-Ökosystems verwendet wird: IANA + Apache + nginx), aus dem Speicher bereitgestellt — kein Key. Lösen Sie einen Medientyp in seine Dateierweiterungen, Zeichensatz und Komprimierbarkeit auf; suchen Sie den/die Medientyp(en) für eine Dateierweiterung (z. B. png → image/png); und listen oder durchsuchen Sie Typen nach Quelle. 2.600+ Medientypen, 1.000+ mit Dateierweiterungen. Schlankes, vorhersagbares JSON. Ideal für Upload-Validierung, Content-Type-Auflösung, Dateityperkennung, Download-Handler und Entwicklerwerkzeuge.

MusicBrainz API
Die offene Musik-Metadaten-Datenbank als API — Künstler, Release-Gruppen (Alben), Releases, Aufnahmen und Labels, identifiziert durch stabile MusicBrainz-IDs (MBIDs), zurückgegeben als sauberes JSON. Durchsuchen Sie jede Entität nach Name oder Lucene-Abfrage; schlagen Sie einen Künstler mit seinen externen Links und Tags nach, ein Album, ein Release mit seiner vollständigen Titelliste, eine Aufnahme mit ihren ISRCs oder ein Label; und durchstöbern Sie die vollständige Diskografie eines Künstlers. Live-Daten mit MBIDs, Disambiguierungen, Typen, Ländern, Lebensspannen, ISRCs, Barcodes, Katalognummern und Relationen — die kanonischen Identifikatoren, die Musikdaten über Dienste hinweg verknüpfen und deduplizieren. Ideal für Metadaten-Anreicherung und -Abgleich, Musikkataloge, Tagging- und Bibliothekswerkzeuge sowie Forschung. 11 Datenendpunkte. Authentifiziert mit einem x-oanor-Key; faire Nutzungslimits pro Plan.
