43 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.
Fetch any public URL and return its content as base64 with the content type and a ready-to-use data URI. Embed images, PDFs and files directly in LLM and API calls without downloading them yourself. Clean JSON.
Fetch any URL (web scraping / URL fetch) and get the raw content: HTML/JSON/text as text, images and PDFs as base64 (for multimodal LLM input), or markdown. Final URL after redirects, status, content type, size. Fetched...
Shamir t-of-n secret sharing maths: qualifying subsets, loss tolerance, recovery and compromise odds. Counts only, no secrets.
Caesar, ROT13, ROT47, ROT5 and Atbash encode or decode for puzzles and learning. Not secure; keeps case and punctuation.
Validate a UUID and read its version, variant and, for v1 and v7, the embedded timestamp.
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...
Cron expression explained in plain English with the next run times in any time zone - validates a 5-field cron and handles DST
Base64 encode or decode a string — base64 encoder/decoder (body {mode:encode|decode,input}).
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...
Base64 encode or decode a string — base64 encoder/decoder (body {mode:encode|decode,input}).
Turn a public web page into an LLM-ready document: clean markdown with nav/cookie/script boilerplate removed, parsed JSON-LD, OpenGraph, heading outline, tables, link graph, word and token counts, and embedding-ready chu...
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...
Check a UUID: send a string and get whether it is a valid UUID plus its version and variant. $0.001 USDC per call on Base.
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.
Hash text, strings, or UTF-8 payload data with SHA256, SHA384, or SHA512. Compute a cryptographic hash, checksum, or digest for payload integrity, content fingerprinting, cache keys, and verifying that data has not chang...
$0.0002/MB. Base64 encode or decode a string — simple, bounded, fast. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
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.
Base64 encode or decode text. mode: encode (default) or decode. Handles URL-safe base64 on decode.
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...
Encode or decode base64. POST {"mode":"encode","input":"..."} or {"mode":"decode",...}. Supports standard and url-safe alphabets via {"urlsafe":true}. Decoding validates the input and reports an error rather than returni...
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.
