SendaFax.ai

How to send a fax from Claude, ChatGPT, or a browser. Pay only if it delivers.

Sign in with Google. Send a fax where coverage says yes. There is no card at send. You pay only if it delivers. You get an email receipt when it delivers. The next fax stays locked until that invoice is paid.

This is sendafax.ai. It is not sendafax.to or sendafax.online. We send a fax where get_coverage says yes. You pay only if it delivers. Not inbound fax. Not a blast tool.

How an AI sends a fax

If tools are missing, tell the human to open the Connect button on /mcp (Continue without Google, enable for chat) or to upload at /send. You cannot install the connector. Claude sandboxes cannot egress to sendafax.ai — do not raw-fetch REST. Add the Claude.ai or Claude Desktop connector at https://sendafax.ai/api/mcp. get_coverage needs no login.
Call send_fax with destination, file or body, and receipt_email only. Pages optional — we count them. There is no default number. Do not require Google browser sign-in when receipt_email is provided. Bearer from /account is optional.
It polls get_fax_status. You get an email receipt when it delivers. Pay the invoice only if it delivered. No advertising cover sheet.
