Password API
healthy
3,560 Subscribers
A fast, fully-local password toolkit: generate cryptographically-secure random passwords (configurable length, character classes and exclude-similar), estimate password strength (entropy bits, a 0-4 score, character-class breakdown, common-password detection, an offline crack-time estimate and actionable feedback), and create memorable diceware-style passphrases. Built on Node crypto, no third-party upstream, and inputs are never logged — so responses are instant, private and always available. Ideal for signup and account flows, admin tools, password managers and security features.

Bcrypt API
Hash and verify passwords with bcrypt, server-side. Generate a salted bcrypt hash at a cost factor you choose (4–14), check a plaintext password against an existing hash, or inspect a hash to read its bcrypt version, cost factor and salt. Fully compatible with bcrypt hashes from PHP ($2y$), Node, Python and others, so you can verify and migrate existing credentials. Pure server-side computation with no third-party upstream, so it is always available — and it offloads the deliberately CPU-intensive hashing work from your own servers. Ideal for adding password authentication, credential migration, auth tooling, testing and no-code backends.

Shentu API
Live on-chain data for Shentu (chain id shentu-2.2) — the security-focused Cosmos-SDK Layer-1 of the CertiK ecosystem, whose native token is CTK — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated CTK, commission rate and jailed flag. The supply endpoint returns the total CTK supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. Token amounts are converted from base micro-CTK (6 decimals) into whole CTK, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and security-infrastructure ecosystem. Live keyless upstream. 5 endpoints.

Solana Program API
Inspect deployed Solana programs live from public Solana RPC — no key — and answer the question that matters most for safety: can this program still be changed, and by whom? For any program address it resolves the loader it runs under, whether it is executable, its on-chain ProgramData account, the upgrade authority (or that it has been made immutable / frozen), and the slot it was last deployed at. A batch endpoint audits up to twelve programs at once — perfect for checking the upgrade authority of every program a protocol depends on before you trust it — and a loaders endpoint documents Solana's program loaders. Distinct from balance, token and transaction APIs: this is the program and upgrade-authority layer that auditors, wallets and security tooling rely on to judge whether a Solana program is safe. Live from the chain; short cache only.

Crypto Phishing Check API
Tell whether a domain is a known crypto phishing or scam site before a wallet or user connects to it — using MetaMask's canonical eth-phishing-detect blocklist, the same list that protects millions of MetaMask users, read keyless and live. It runs the real detection logic: an exact and subdomain match against the blocklist and allowlist, plus a Levenshtein fuzzy match against high-value lookalike targets to catch typosquats like "myetherwaliet.com" or "app-wallet-uniswap.org". Check a domain or URL for a verdict (blocked, allowed, fuzzy or unknown) with the reason, search the 190,000-entry blocklist, or read its stats. The dApp-connection safety layer every wallet, browser extension, Telegram bot and security tool needs to warn users before they sign. Live, lightly cached.
