Create a new receiver (a prospect or contact) in Pitch Machine. audience_mode='b2b' requires company_name + contact_email. audience_mode='b2c' requires receiver_email. Returns receiver_id, used as the input to pitchmachine_generate_pitch.

Kick off pitch generation for an existing receiver and poll until it completes. Returns the public share URL (pitchmachine.ai/p/?t=) on success. If generation takes longer than poll_timeout_seconds, returns the in-progress status; call pitchmachine_get_pitch_url later with the returned pitch_id. Does NOT send the pitch — that's the agent's job (or a human's).

Fetch the current state and public share URL for a pitch by pitch_id. Use this to resume after pitchmachine_generate_pitch timed out, to re-share a URL later, or to check the status of any past pitch.

List recent pitches for the authenticated Pitch Machine account. Use this to discover pitch_ids for pitches created outside this agent session, or to audit what an agent has already generated. Optional filters: status_filter, since (ISO timestamp), limit.
