71 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.
URL encode. Percent-encode text for use in a URL query value (encodeURIComponent) and as a full URL (encodeURI). Use when building query strings.
Base32 (RFC 4648) encode or decode text. mode: encode (default) or decode.
Base58 encode or decode text (Bitcoin/IPFS alphabet). mode: encode (default) or decode.
Base64 encode or decode text. mode: encode (default) or decode. Handles URL-safe base64 on decode.
Compress a string with Brotli (RFC 7932) and return it as base64. Brotli typically beats gzip by 15-25% on text - useful when bytes matter (e.g. cramming context into an LLM prompt, fitting under a transport cap). Slower...
CRC-32 checksum of a text string (hex), the IEEE polynomial used by zip/png/gzip.
Caesar-cipher a string. Default shift 13 (ROT13, self-inverse). Set shift for any rotation 1-25.
Decode a JWT without verification: header (algorithm), payload claims (subject, issuer, expiration), expiry status, and time remaining. (Decoding only - signatures are NOT verified.)
Mint a signed JSON Web Token (HMAC: HS256 default, HS384, HS512) from a payload + secret. Pairs with jwt-decode/jwt-verify to complete the trio. Deterministic - same payload, secret, and alg always produce the same token...
The current time, or a given time, in one or more IANA time zones, with UTC offset, abbreviation, whether daylight saving time is in effect, and the weekday. Give a local time with from_tz to convert it, handling DST cor...
Hex encode or decode text. mode: encode (default) or decode.
Encode text to HTML entities or decode them back. mode: encode (default) or decode.
Verify an HS256/384/512 JWT signature against a secret and check expiry. Returns valid + decoded payload. (HMAC algorithms only.)
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
Encode/decode hex for $0.002 USDC for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the s...
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...
Breached password check: is this password in known data breaches, and how often? Send only the SHA-1 hash (never the password); just the first 5 characters reach Have I Been Pwned (k-anonymity). Up to 50 hashes per call.
Convert text between utf-8, base64, hex, URL-percent-encoding and ascii representations.
Resolve ENS (.eth) on Ethereum and Basenames (.base.eth) on Base, forward or reverse. Returns address, name, source, forward_verified, optional avatar.
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.
Decode and checksum-verify a bech32 or bech32m string — Genesis402 / UnyKorn Operator Network
