Probe an endpoint

Paste a paid endpoint. This asks it what it costs and shows you the answer it gave — the price, the chain, the asset, and who gets paid.

This reads the price and never pays it. A probe is one unauthenticated GET. It sends no payment header, carries no signer, and there is no code path behind this form that could spend money. A 402 response is a public offer — that is what makes it readable by anyone.

Nothing is stored. The URL is fetched once and the answer returned; no row is written and no record is kept of what was asked.

Because this fetches a URL a stranger supplies, it refuses loopback, link-local and private addresses, re-checks anything a redirect points at, follows at most one hop, and stops reading at 64 KiB.
