35 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.
Prove you had this sha256 at this time: signed receipt with its position in neo's public log, anchored daily on Bitcoin (OpenTimestamps) and Software Heritage.
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.
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...
Timestamp SHA-256 hashes in Bitcoin with OpenTimestamps: returns a standard .ots proof per hash (pending, complete within hours), verifiable without us
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.
SHA256 hash, SHA-256. Hash UTF-8 text with SHA-256 (default), SHA-1, SHA-384 or SHA-512 and return the digest in hex and base64. Use for checksums, cache keys and deduplication.
Give this API any text or binary data and it returns its fingerprint under whichever hash algorithms you choose - SHA-256, SHA-512, MD5, BLAKE2, CRC32 and more. It also signs data with a secret key (HMAC) and safely veri...
Keccak hash, keccak256. Keccak-256 hash (the Ethereum hash) of text or of 0x hex bytes, as used for function selectors, event topics and storage slots. Use when building or decoding EVM calls.
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...
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...
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...
SHA-256 hash of any text, plus SHA-1, SHA-512 and MD5 - send text, get the hash digest as hex or base64
Argentina official gazette (Boletin Oficial) keyword search returning literal excerpts of matching notices with dates and source URLs; an optional date limits the search to that day's notices. Use this when an agent need...
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...
Cyre Pay-route Oracle — before your agent pays any external x402 resource, grade payTo + amount/URL + facilitator/offer pin hygiene in one call. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Keccak-256 of any string or hex payload - the hash Ethereum actually uses, which is NOT the same as SHA3-256. Needed for selectors, event topics, salts and CREATE2 addresses.
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...
Current time from a trusted server: UTC ISO timestamp, Unix seconds and milliseconds, and the time in an optional IANA time zone.
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...
imagepeek (Tanod) image metadata: EXIF, GPS, XMP, IPTC and ICC. Use when an agent needs an image's EXIF, GPS, XMP, IPTC or ICC metadata.
CRC-32 checksum of a text string (hex), the IEEE polynomial used by zip/png/gzip.
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...
