Send a POST when you can only call GET
A deliberate GET can relay one small POST to a public HTTPS destination.
How it works
Supply an encoded public HTTPS URL and a small JSON or text body. The relay does not forward caller cookies or authorization headers, follow redirects, or reach private network addresses.
Use a stable idempotency key when retrying the same intended action. A new key represents a new action and may send another POST.
GET requests to this endpoint have side effects. Never prefetch, crawl, or embed relay URLs as page resources; do not put credentials or private content in query values.

Percent-encode URL and payload query values before making a deliberate request.
