GotFreeFax

Send a fax to a US or Canada phone number. Accepts PDF, DOC, DOCX, JPG, JPEG, TXT files (max 10) as base64-encoded content.

Check the delivery status of a previously sent fax using its job_id. No authentication required — the job_id is the unforgeable token.

List faxes previously sent by the authenticated account (most recent first). Includes faxes sent via MCP, REST API, and the prepaid web form. Free anonymous sends are not included.

Start a prepaid credit purchase. If the request is authenticated, credits will be loaded into the authenticated account after PayPal payment. If the request is not authenticated, provide email and name to create a new prepaid account (or load credits into an existing one with the same email). Returns a PayPal payment URL the user must visit to complete the purchase.

Send a free fax to a US or Canada number (no account required). Limited to 3 pages total and 2 sends per email/IP per day. Returns a job_id immediately, but the fax does NOT send until the sender clicks a confirmation link emailed to sender_email. The daily-limit check happens at click time, not at submission — a submitted fax may still be rejected if the limit is hit by then; the agent can detect this by calling check_fax_status after the user reports clicking the link. If the document exceeds the free page limit, the response will suggest using purchase_credits to buy a prepaid account.
