POST /api/v1/alerts/subscriptions

unprobed

Use to get pushed instead of polling: one POST buys a 7-day pack of up to 200 signed webhook deliveries to your HTTPS URL. Events: decision_change, unusual_flow, funding_extreme (Hyperliquid), material news, token_risk_change for up to 5 watched tokens. Filter by symbols, news categories and materiality.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
