Ethos API v2

Create an Ethos profile at app.ethos.network linked to your wallet, then follow the API Keys guide. You mint a long-lived key by signing a one-time SIWE message and calling POST https://api.ethos.network/api/v2/api-keys; the returned token is then sent as X-Ethos-Api-Key. API key access must be enabled for your account.

Sign in to app.ethos.network. For authenticated API calls in an active user session, use the short-lived Privy token described in the Introduction and Log in with Ethos docs. The docs state it is stored in the privy-token cookie for the app.ethos.network domain and is sent as Authorization: Bearer <token>.
