Percent-encode or decode a string for URLs. mode: encode (default) or decode. component: true (default) uses encodeURIComponent semantics.

URL encode or decode a string (percent-encoding) for query, path or fragment.

URL encode or decode a string (percent-encoding) for query, path or fragment.

URL parser: parse and canonicalise a URL, and extract its registrable domain using the Public Suffix List — the part an agent needs to decide whether two URLs belong to the same owner. Returns scheme, host, port, path, decoded query parameters and fragment, the public suffix, the registrable domain (eTLD+1), the subdomain, whether the suffix is ICANN or private, plus a canonical form with default port, dot-segments and percent-encoding normalised. unicode_host uses WHATWG/UTS 46 (non-strict).

Canonicalize a URL: WHATWG parsing already lowercases the host, resolves dot-segments and drops default ports; on top of that, query parameters are sorted by default and you can optionally drop the f…

Parse an absolute URL into its WHATWG components: protocol/scheme, credentials, host/hostname/port, origin, pathname (plus path segments), search (plus a decoded query object) and hash. A string that…

Resolve a relative or absolute reference against a base URL, following RFC 3986 reference resolution (e.g. base 'https://a.com/x/y' + ref '../z' → 'https://a.com/z'). The base must itself be a valid …

Pay a tiny amount of USDC and receive one delightfully useless fact.

Heuristic user-agent string parser: browser, version, OS, device class, and bot detection.

Parse a User-Agent string into browser, engine, OS, device type/vendor/model and CPU, and flag bots and AI crawlers (GPTBot, ClaudeBot, PerplexityBot ...). Params: user_agent (required).

Parse a User-Agent string: browser and version, OS and version, device brand and model, device type (mobile, tablet, desktop) and whether it is a bot, an AI crawler (GPTBot, ClaudeBot...) or an HTTP library.

Classify a User-Agent by device form factor and return convenience booleans (isBot, isMobile, isTablet, isDesktop, isTouchCapable) for routing decisions.

Break a User-Agent string into browser, engine, operating system (each with a version) and device type. Unidentifiable components are reported as null.

Current UTC unix time. Use for idempotency stamps, expiring links, or clock skew checks. Returns unix seconds, millis, and ISO UTC from the server clock. $0.001 USDC per successful call via x402 on Base or Solana—first-party JSON from Delx (fresh each call; not a deterministic transform), no API key, no subscription, and nothing is billed on structured validation errors.

Tiny deterministic utility API for agents: current time across timezones, UUID v4 generation, cryptographically secure random numbers, and base64 encode/decode. Live on Base mainnet (eip155:8453) — pay in real USDC and call it in production. No external dependencies, sub-millisecond responses.
