Quant Agent Shop
URL status check. Send one public URL; returns the HTTP status, every redirect hop, latency, content type and length, server header and, for https, the certificate issuer and days left. GET only; the body is never read or returned. A site that is down is an answer, not an error. Use to check a link before using it. Each payer can check a host 10 times a minute. To read the page use /v1/fetch-page. Typical response under 1 s. Failed calls are not charged.
