Decodes up to 20 vehicle identification numbers with NHTSA's vPIC database (US public domain): make, model, model year, trim, body class, vehicle type, engine (cylinders, displacement, fuel), drive type, plant country and city, manufacturer, and the decoder's own error code and message. The check digit is verified for North American VINs. A VIN that is not 17 characters without I, O or Q is a 400.

A site's brand assets: its icons (favicon, apple-touch-icon and web app manifest icons, largest first), the og:image, theme colour and site name, read from the page and its manifest. Falls back to /favicon.ico when the page declares no icon.

For eleven AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and others): allowed or blocked for the page's path under robots.txt, plus the noai and noimageai opt-outs in meta and X-Robots-Tag, and whether llms.txt exists. Reads the page as static HTML; no JavaScript runs.

Read-only contract call (eth_call): decodes the return value of a function you name, e.g. balanceOf(address) returns (uint256). Nothing is signed or sent. A function whose name reads like a write (transfer, approve, mint, set...) is refused unless it is declared view or pure.

Convert a value between units of length, area, volume (US customary and metric, cooking measures), mass, speed, pressure, energy, power, data size (SI and binary), time and temperature. Factors are exact to the definitions in NIST SP 811 (international inch and pound, US gallon, calorie IT, Btu IT, mechanical horsepower). An unknown unit is a 400 that lists every supported unit. Pure code, no outside source.

Checks up to 10 UK EORI numbers (GB or XI followed by 12 or 15 digits) with HMRC's public check: valid or not, with the processing date.
