# Radius pricing

Machine-readable pricing for Radius's paid endpoints, by catalog. Prices are per request, in US dollars.

A request without payment is answered `402 Payment Required` with x402 payment requirements; send it again with payment. A request beyond a rate limit is refused with `429 Too Many Requests`, whether or not it pays; wait for the window to reset (the `Retry-After` header, when sent, says how long). Every request counts against its endpoint's rate limit and free quota.
