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.
Compute a SHA-256 digest for customer-supplied UTF-8 or base64-decoded bytes through a stable machine endpoint. Returns the reproducible digest through a receipted external execution.
Hash generator: compute a cryptographic digest of supplied data: SHA-256, SHA-384, SHA-512, SHA-1, SHA3-256, SHA3-512, Keccak-256, BLAKE2b-256 and BLAKE2b-512, plus HMAC with any of them. Input is UTF-8 text, base64 or h...
Identify an Android APK by file hash: MD5, SHA-1 or SHA-256 to the app, version and build it belongs to. Reverse lookup for a file from a device or a checksum from a threat-intelligence feed, with no package name needed....
Inspect a UUID: valid or not, version (1-8), variant, and the embedded timestamp for v1, v6 and v7 UUIDs.
Validate a UUID and read its version, variant and, for v1 and v7, the embedded timestamp.
SHA-256 hash/digest of a text string — also sha512 and sha3-256; returns hex.
Compute SHA256 hash or SHA-512, SHA-1 and MD5 checksums for UTF-8 text and return hex plus Base64 digests. Use for SHA256 hashing, checksum verification, integrity checks, content fingerprints, cache keys, deduplication...
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...
Use when an agent must prove two payloads are the same byte for byte, or sign an API request: SHA-256 of any string or hex payload, returned as hex and as base64, which are the two forms signatures and content addresses...
SHA256 hash, SHA-256. SHA256 hash of UTF-8 text (SHA-256 by default; SHA-1, SHA-384 or SHA-512 on request), returned as a digest in hex and base64. Use for checksums, cache keys and deduplication.
SHA-256 hash/digest of a text string — also sha512 and sha3-256; returns hex.
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...
Hash generator, hash toolbox. Every common hash of one input in a single call: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256 (Ethereum), CRC-32, base64 SHA-256, and Subresource Integrity strings (sha256-, sha384-, sh...
Compute keccak256/sha256, a 4-byte function selector, an event topic0, or an ENS namehash/labelhash from a string or hex input.
Compute cryptographic digests and HMACs deterministically: MD5, SHA-1, SHA-256, SHA-384, SHA-512, output as hex, base64, or base64url. Add a "key" for HMAC. Built for checksums, content addressing, and signature verifica...
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...
Compute MD5, SHA-1, SHA-256, SHA-512, and CRC32 checksums of a string in a single call. Useful for verifying file or payload integrity across different checksum standards without needing five separate tools.
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...
Detect a text's language offline across 75 languages. Use when an agent must identify which language a piece of text is written in.
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...
Convert between unix epoch and human time: pass ?value=<seconds|ms|ISO-string> and get back epoch (s + ms), ISO-8601 UTC, and the value in a target timezone (?tz=America/Santiago, default UTC). Units are auto-detected (1...
Resolve ENS (.eth) on Ethereum and Basenames (.base.eth) on Base, forward or reverse. Returns address, name, source, forward_verified, optional avatar.
Compute keccak256/sha256, a 4-byte function selector, an event topic0, or an ENS namehash/labelhash from a string or hex input.
