• draft_letter

  Create a letter DRAFT: verifies the recipient address with PostGrid, screens content, and returns a price quote. This NEVER mails anything. Pass EITHER html (letter body as an HTML string) OR pdf_path (path to a PDF file on the server). PDF text is extracted for screening; if ex…

• request_send

  Request that a draft be mailed. approval-tier keys: creates a PENDING request and returns a one-tap Allow/Deny approval_url for the human. Nothing is mailed until Allow. on_command keys: may auto-send inside guardrails (spend caps, content screening, anomaly detection); anything…

• send_status

  Check a send request: status (PENDING/SENT/REJECTED/FAILED), the key's trust tier and tier decision, approval state (+approval_url while pending), and billing state (Stripe charge id when billed).

• create_fax_draft

  Create a fax DRAFT: validates the recipient number, counts the PDF's pages, screens its text, and returns a price quote (Phaxio per-page cost x pages + the flat $1.00 service fee). This NEVER transmits anything — call approve_fax, then send_fax.

• approve_fax

  Approve a fax DRAFT so it can be transmitted. The content is re-screened at approval time. Only the key that created the fax can approve it. Nothing is transmitted by this call — send_fax does that.

• send_fax

  Transmit an APPROVED fax via Phaxio. Refuses drafts that were never approved and faxes that were already sent — a fax can be transmitted exactly once.

• get_fax_status

  Check a fax: lifecycle status (DRAFT/APPROVED/SENT/FAILED), page count, quote, and — once sent — the live delivery status from Phaxio.
