Tools (3)

`create_context`	Share text, markdown, code, or HTML as an auto-expiring ctxt.io link. For visual output (styled reports, tables, charts, diagrams) prefer format=html with self-contained HTML: inline CSS and inline SVG render fully; <script> is stripped server-side and JavaScript never runs, so keep it static. Free expiries: 5m, 30m, 1h (default), 8h, 1d — these return the share URL immediately. ttl=30d and the Pro options (name, password) cost $1 one-time: the link is created in a pending state and the result includes a payment_url a human can open in a browser to complete checkout (platforms enrolled for agentic payments receive an acp block instead and can pay programmatically); until payment the link lives 1 day without Pro features. Anyone with the link can read it. The returned delete_token authorizes deletion via delete_context — keep it private.
`delete_context`destructive	Delete a ctxt.io link you created. Requires the delete_token returned by create_context. Immediately removes public access and requests backing-storage deletion. Destructive and not undoable — confirm with the user before calling.
`read_context`read-only	Fetch the content of an existing ctxt.io link. Accepts a full ctxt.io URL, a /3/<code> path, or a bare code. Password-protected links need the password argument.
