Send a link, get a cited knowledge packet — flat $0.01
$0.01POST https://know.fast/v1/knowONE CENT FOR EVERYTHING, ALWAYS AN INSTANT ANSWER. A link anyone has already known answers instantly ({"cached": true} plus the inline `packet`); a first-ever link answers instantly too, with a deferred run ({"deferred": true, "knowledgeReady": false} plus statusUrl/markdownUrl/viewerUrl) — reply to your user right away and share viewerUrl, poll statusUrl (public JSON, no auth) until knowledgeReady, then GET markdownUrl for the packet. Articles land in about a minute; video/podcast in minutes (we absorb transcription costs). Every knowledge page is durable and citable, and every read of a known link is a cache hit for every future agent — the knowledge base compounds. Pass {"fresh": true} to re-read changed content (same price). Failures are not charged and dead links answer free from the failure cache.
