Read a reviewed host-managed connection plan for Exa, Jina or Browserless. Only provider is accepted. Returns official endpoints, authentication method, setup steps, source evidence and account-check limitations. Configure credentials only in your agent host; Relay does not inspect accounts, perform OAuth, accept keys or execute authenticated provider tasks. Discover live provider tool schemas after connecting. Connection grants no payment permission: the host must enforce the user's budget and provider billing controls before charged work. Unpublished or changed listings return no usable connection options. No provider calls or writes.
