Server instructions

ctxt.io shares text, markdown, code, or HTML as auto-expiring links. create_context returns the share URL plus .md/.txt/.json variants of it. For visual output (reports, tables, charts) prefer format=html with self-contained HTML: inline CSS and inline SVG render; scripts are stripped and never run. Expiries up to 1 day are free. ttl=30d and the Pro options cost $1 one-time: the result then includes a payment_url that a human can open in a browser to complete checkout.
