  • encode_base64

    Encode UTF-8 text as standard Base64 (padded, A-Z a-z 0-9 + /), for embedding binary-unsafe content in JSON, data URIs, HTTP headers or Basic auth. Returns JSON { encoded }. The output uses the standard alphabet, so it is NOT URL-safe: '+' and '/' must still be percent-escaped b…

  • decode_base64

    Decode a Base64 string back to UTF-8 text. Returns JSON { decoded }. Input is verified by re-encoding, so anything that is not genuine Base64 is rejected with an error instead of returning plausible garbage; binary payloads that are not valid UTF-8 will also fail. It handles Bas…

  • decode_jwt

    Decode a JWT's header and payload for inspection. Returns JSON { header, payload, signatureVerified, note, expiresAt, isExpired } — structured objects, not a rendered table. The signature is NEVER verified: that needs the issuer's key, which this service does not have, so signat…

  • format_json

    Validate and re-print a JSON string. Returns JSON { valid, formatted, minified } — the indented form and the whitespace-free form as plain strings, with no syntax highlighting or colour. Invalid JSON is rejected with the parser's own error message rather than returned as valid:f…

  • calculate_percentage

    Run one of four percentage calculations on two numbers. Returns JSON { operation, result } (plus unit: 'percent' for the 'change' operation). The meaning of value1 and value2 depends on the operation, so read their descriptions before calling. Exact arithmetic, no model involved…
