Api Endpoint

SWARM

SWARM Site Check - Website uptime and link check in one call: is a URL up, its HTTP status, final URL after redirects, response time and TLS/certificate errors. Use when an agent monitors sites on a schedule, verifies a link or domain is reachable before scraping or citing it, or needs to detect a non-200 answer or a broken redirect. Requires `url`. Instant, no AI. $0.002.
