security.txt API

3,518 Subscribers
Fetch and parse any domain's RFC 9116 security.txt — the machine-readable file at /.well-known/security.txt that tells security researchers how to report vulnerabilities. Pass a domain and the service locates the file (the canonical .well-known path with a legacy root fallback), parses every field — Contact, Expires, Encryption, Acknowledgments, Preferred-Languages, Canonical, Policy, Hiring and CSAF — and reports whether it is valid (has at least one Contact and a single, non-expired Expires), whether it is PGP-signed, whether it has expired (with the number of days remaining) and a list of issues with concrete advice. A companion endpoint returns the raw file. The request is made server-side; private and internal targets are refused (SSRF-guarded). Built for security audits, vendor and third-party risk assessment, attack-surface reviews and vulnerability-disclosure-policy compliance checks. A security.txt parser and validator — distinct from the HTTP security-header grader (secheaders), the SSL/TLS certificate check (sslcheck) and host reachability (hostcheck). No upstream key, no cache.

robots.txt API
Fetch and evaluate any website's robots.txt. Pass a URL and a user-agent and the check endpoint tells you whether that URL is crawlable — selecting the most-specific user-agent group and applying the RFC 9309 longest-match Allow/Disallow rules (with * and $ wildcards, where Allow wins ties), and returning the matched rule, the group's crawl-delay and the sitemaps the site declares. The parse endpoint returns the whole file structured into per-user-agent groups (their allow and disallow lists and crawl-delay) plus the list of sitemaps. A missing robots.txt (404/403) means everything is allowed, exactly as the spec requires. The request is made server-side and private or internal targets are refused (SSRF-guarded). Built for SEO audits, crawler and scraper compliance, sitemap discovery and pre-flight "am I allowed to fetch this?" checks. A robots.txt evaluator — distinct from the on-page SEO audit (seo), the XML toolkit (xml) and link unfurling/preview (url). No upstream key, no cache.

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.
