Matching Markets by URL

Find matching markets by providing a URL from any supported platform. The platform is auto-detected from the URL hostname. Novig deep links resolve by the outcome id in their path. Polymarket US is not resolvable here (it publishes no web market pages); reach its markets through /v2/markets?platform=polymarket_us or the group returned by any other leg.
