58 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.
MD5, SHA-1, SHA-256, SHA-512, SHA3-256, Keccak-256, BLAKE2b and CRC32 of a text or hex/base64 bytes, plus base64 and hex encodings, in one call. Use for integrity checks, IDs, signatures and Ethereum selectors.
Compute an HMAC (MD5, SHA-1, SHA-256 or SHA-512) of text with a given key.
Compute an MD5, SHA-1, SHA-256 or SHA-512 hex digest of text.
Canonical digests — sha256, sha512-256 and blake2b of text or canonical JSON — Genesis402 / UnyKorn Operator Network
Base transaction explained from the chain: success or reverted, block and time, from, to, ETH value, method selector, gas used and fee, contract created, and every ERC-20 transfer decoded with token symbol and amount. In...
SHA-256 hash API for agents: hash text with SHA-256, SHA-1, or MD5 for $0.001 USDC and return a compact deterministic receipt—not a password KDF. Call when you need this bounded result without an API key or subscription....
Compute cryptographic digests of a string. POST {"input":"...","algorithms":["sha256"]} and receive one hex digest per requested algorithm. Supports sha256, sha512 and keccak256. Deterministic, no storage, no upstream ca...
Check whether a phone number is valid and possible, find its country and type (mobile, fixed line, toll free and others), and format it as E.164, international and national (libphonenumber metadata).
Generate a cryptographic hash of text: SHA-256 (default), SHA-384, SHA-512, SHA-1 or MD5, returned as a hex digest. Pure CPU, instant, no upstream. Use to fingerprint a string, verify a payload or compute a checksum.
Hash any UTF-8 string and get sha256, sha512, sha384, sha1, md5, CRC32 and base64 checksum in one call. Computed locally, no upstream, no API key.
Page change detection - website change monitoring, detect webpage changes, url change detection. Fetches a public URL and reports whether the page changed: the sha256 fingerprint of the text a reader sees, the HTTP statu...
Monitor a page for changes: url change monitor with before/after sha256 and the diff.
Fetch any page as clean markdown plus the sha256 of the extracted text.
Did this page change, plus before and after sha256.
Should your agent buy this token? Keyless token risk verdict: honeypot check, mintable, hidden owner, buy/sell tax, top-10 holder concentration (GoPlus) plus price, liquidity and 24h volume (DexScreener) -> avoid|caution...
Text hashes: SHA-256, SHA-1, SHA-512 and SHA-384 hex digests of the exact text you send (UTF-8), plus its byte length. Deduplication keys, integrity checks and fingerprints. $0.01 per call.
Checksums of a file at a URL (up to 5 MB): SHA-256, SHA-1 and MD5-free SHA-384 hex digests, the SRI string (sha384-…), byte size, content type, last-modified and ETag, plus the final URL after redirects. Verify downloads...
Public URL verification API for AI agents. Independently fetch one public HTTP(S) URL and return target HTTP status, final URL, raw response-body SHA-256 content fingerprint, content type/encoding, byte length, and UTC o...
Validate a sha256: tests the value against a well-known sha256 pattern and returns valid true/false, the pattern used (so you can reuse it), and, when it fails, the first character position that breaks the rule. Format v...
Deterministic canonical JSON + SHA-256 fingerprint
Run a deterministic SHA-256, base64 encode/decode, or UUID utility and return structured JSON.
Use when an agent is about to give a user links or citations: send up to 10 URLs, and get back the status, redirect chain, final URL, title and hash of each, so a dead, moved or blocked link is caught first. A URL whose...
JSON canonicalization — canonicalize structured data with RFC 8785 JCS; return canonical JSON text, UTF-8 byte length, and SHA-256 hash for integrity checks, signature preparation, and deduplication. Includes an EIP-712...
SHA-256, SHA-384, SHA-512 or SHA-1 of any text in one GET, without an LLM or a local tool: pass text and get the digest as hex or base64. curl: GET /hash?text=hello (algo sha256|sha384|sha512|sha1, default sha256; encodi...
