I need the WebSocket quote stream. It is the one endpoint that always requires a key — everything else works without one.

You don't need a key to start

curl "https://api.vulcx.xyz/api/v1/quote\
?inputMint=So11111111111111111111111111111111111111112\
&outputMint=uSd2czE61Evaf76RNbq4KPpXnkiL3irdzgLFUMe3NoG\
&amount=1000000000\
&swapMode=ExactIn"

Quote, swap, instructions and price all answer anonymous requests at 1 cost unit per second. A key raises that to 100, and is required for the WebSocket stream. Nothing else changes.

Prefer to just ask? Telegram still works.
