Give this API a link to any website's sitemap.xml file and it will fetch and parse it, returning every URL found inside. If the sitemap links to other sitemaps (called sitemap indexes), it will follow and extract those too. Each URL is returned with any extra information available, such as when the page was last updated and how often it changes. Useful for SEO audits, content inventories, broken link checks, and competitive research.

Pass city=<name> (alias location=, optional country= ISO 3166 alpha-2 filter) instead of lat/lon: resolved against the embedded GeoNames cities500 gazetteer (exact name match, case- and accent-insensitive, most populous match wins — no fuzzy matching), and the resolved place is echoed back as data.location.

They backtest any factor over 5+ years of history (Metric Slicer), fork and validate custom signal recipes (Signal Forge), scan the universe for live matches, decompose per-asset conviction across every factor class, and query the full stack in natural language. The loop: define your conviction thesis → validate it against history → scan for live matches → execute via OKX, Kraken, or Coinbase execution toolkits. CRYPTYX is the brain; exchanges are the rails.
