POST /v1/watch
method-gated
Watch the crypto market for 24 hours: up to 10 conditions (price, % change, funding, open interest, liquidations, order book, Fear and Greed, whale orders, news impact), checked every minute; when one happens you get a signed webhook and it shows in the watch's status.
Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.
