Official US vehicle fuel-economy data as an API, powered by FuelEconomy.gov — the joint US EPA and Department of Energy resource behind the fuel-economy window sticker on every car, SUV and truck sold in the United States since 1984. Browse the catalogue step by step — model years, then makes, then models, then the engine/transmission trims (each carrying the vehicle id you need for the detail call) — and pull a vehicle's complete fuel-economy record: city, highway and combined MPG, fuel type, engine (number of cylinders and displacement), transmission, EPA vehicle class and drivetrain, the estimated annual fuel cost, tailpipe CO2 emissions in grams per mile, the barrels of petroleum consumed per year and the estimated five-year fuel-cost saving (or extra spend) versus an average new vehicle. Ideal for car-shopping and comparison tools, total-cost-of-ownership and emissions calculators, fleet management and sustainability reporting. The data is authoritative, official EPA/DOE test data and is public domain; it covers US-market light-duty vehicles. Vehicle ids come from the trims endpoint, reached via the year -> make -> model -> trim chain.

The European Union open-data portal as an API, powered by data.europa.eu — the official single point of access to more than 1.8 million open datasets published by the EU institutions and harvested from the national open-data portals of all 27 member states (including data.gov.uk, data.gouv.fr and GovData Germany). Search datasets across every theme — energy, health, transport, environment, agriculture, economy, justice and more — with optional filters by file format and by publishing country, getting each dataset's identifier, English title and description, publisher, source portal, country, available formats, resource count, last-modified date and licence; read a dataset's full metadata together with all of its downloadable distributions (each distribution's title, format and direct URL), plus categories, keywords, languages and temporal coverage; and explore discovery facets for any query — the most common file formats and the countries publishing matching datasets. Ideal for data journalism, civic-tech and govtech applications, research, market and policy analysis, and any tool that needs to find and download European public-sector information. Dataset identifiers come from search results; titles and descriptions are returned in English where available. Data from data.europa.eu (licences vary per dataset; most are CC-BY or public domain).

US banking data as an API, powered by the FDIC BankFind Suite — the official open data service of the Federal Deposit Insurance Corporation. Search the roughly 4,500 FDIC-insured banks by name and state (active, inactive or all), getting each bank's FDIC certificate number, name, city and state, total assets and deposits, branch-office count, charter class and founding year, ranked by size; read a single bank's full profile including its address, website, established and (if applicable) closed dates, total assets, deposits, equity and net income, branch count, charter class and type, primary federal regulator, deposit-insurance fund and business specialization; track a bank's quarterly financial performance over time — assets, deposits, equity, net income, net loans, return on assets, return on equity and net interest margin; and browse the complete history of US bank failures since 1934, with each failure's date, resolution type, acquiring institution, total assets and deposits and the FDIC's estimated cost — including recent high-profile failures such as Silicon Valley Bank, Signature Bank and First Republic Bank. Ideal for fintech, financial research, risk analysis, journalism and compliance tooling. Identify a bank by its FDIC certificate number from search results; all dollar figures are reported in thousands of US dollars. Data is public-domain from the FDIC (US institutions only).
