53 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Cryptographic hash of a text string - sha256 (default), sha512, sha1 or md5 - returned as hex and base64. Use it for content fingerprints, integrity checks and deterministic ids; pure computation, instant.
CUDA, driver and Ollama compatibility - GPU support, model memory fit and proof inference uses the GPU
Email validation API. Checks whether a string is a syntactically valid email address using the same production-grade validation library trusted across the Node.js ecosystem, catching edge cases a quick regex misses. Retu...
Encoding toolbox. Every common encoding of one text in a single call: Base64 and Base64url, hex, URL component and full-URL encoding, HTML-escaped, ROT13, Unicode code points, UTF-8 byte count and Punycode for internatio...
Base64 decode. Decode standard or URL-safe base64 to UTF-8 text. Missing padding is tolerated. Use to read encoded headers, tokens and data URLs.
Base64 encode. Encode UTF-8 text as standard base64, and also return the URL-safe variant. Use for data URLs, headers and basic auth strings.
URL encode. Percent-encode text for use in a URL query value (encodeURIComponent) and as a full URL (encodeURI). Use when building query strings.
JWT decode. Decode a JSON Web Token's header and payload without verifying the signature, and report issued-at, not-before and expiry as dates and whether it has expired. The token is not stored. Do not use the result to...
Mojibake Repair: Undo Broken Encoding Exactly — Repairs mojibake, text whose accents, Cyrillic letters, quotes, dashes or emoji turned into strings such as è, ü, “, пр or Р—Рґ because UTF-8 was read as Windows-1252...
Hex encode or decode text — hex string encoder/decoder.
One endpoint for hashing and encoding: sha256, sha512, sha3, keccak256, md5, sha1, blake2, ripemd160, crc32, all-hashes-at-once, HMAC, base64/base64url, hex, URL and base58 encode/decode, JWT decode (with expiry check) a...
Morse code translator. Translate text to international Morse code (letters separated by spaces, words by /) or Morse code back to text; the direction is detected automatically or set with mode. Letters, digits and common...
Caesar cipher, ROT13. Encode or decode text with a Caesar cipher: every letter A-Z shifted by 1-25 places (13, the default, is ROT13), case kept, digits and punctuation untouched. decode=true shifts back. Use for puzzles...
Hex encode or decode text — hex string encoder/decoder.
Base64 in both directions, including the URL-safe alphabet, with UTF-8 handled properly. Encoding is what carries payloads through headers and JSON, and x402 itself rides on it.
Compute the current TOTP code (RFC 6238, 30s period, SHA-1, 6 digits) from a base32 secret. Useful for agents that must complete 2FA flows they are authorized for.
Encode or decode text: base64, base64url, hex, URL percent-encoding, HTML entities, ROT13, binary, Unicode escapes and punycode, or detect to try decoding unknown input.
Inspect one public MCP HTTP endpoint, auto-detect the stateless 2026-07-28 era or fall back to the legacy initialize lifecycle, then normalize tools/list schemas into a deterministic SHA-256 contract fingerprint. Forest...
SWARM Site Check - Website uptime and link check in one call: is a URL up, its HTTP status, final URL after redirects, response time and TLS/certificate errors. Use when an agent monitors sites on a schedule, verifies a...
Hex encoding of UTF-8 text — Genesis402 / UnyKorn Operator Network
RFC 4648 base32 encoding — Genesis402 / UnyKorn Operator Network
Decode base58 to bytes — Genesis402 / UnyKorn Operator Network
Greatest common divisor and least common multiple of two or more integers, computed exactly (arbitrary precision). Useful for cycle alignment, scheduling periods and fraction work. Signs are ignored; a zero makes the LCM...
Decode a JWT without verification: header (algorithm), payload claims (subject, issuer, expiration), expiry status, and time remaining. (Decoding only - signatures are NOT verified.)
