        "note": "Convert integers between numeral systems with exact big-integer math. /v1/convert?number=ff&from=16&to=2 converts a number from one base to another (radix 2–36, arbitrarily large, with sign and the decimal value); common prefixes 0x, 0b and 0o are accepted when they match the base, and whitespace/underscores in the input are ignored. /v1/bases?number=255 shows a number across binary, octal, decimal, hexadecimal, base32 and base36 at once, plus its bit length, byte length and sign. Everything is computed locally with BigInt, so values of any size are exact. Ideal for low-level debugging, embedded and networking work, teaching, and anywhere you juggle hex/binary/decimal. A numeral-base converter — distinct from the text-encoding toolkit (encoding: base64/base32/hex of bytes), the Elixir Hex package registry (hex) and number-to-words (numberwords). No key, no cache.",
