## What we do

Upload a PDF, Word, Excel, PowerPoint, RTF, plain text, or image. We convert to PDF before sending. Domestic sending starts at $0.99 for up to 10 billable pages, then about $0.08 per extra page (cap 100). Receive uses a dedicated fax number. Email-to-fax is send@fax.delivery.

Agents install MCP at https://singlefax.com/agents or call the REST API at https://singlefax.com/developers and https://singlefax.com/openapi.json.

## Who we are

Operated by Monocube LLC (Wyoming). We do not sell your documents or add third-party ads to your fax. SingleFax-generated cover pages include SingleFax branding. If your fax already includes your own cover page, or you upload a separate cover file, we add no additional SingleFax branding. Payments go through Stripe. Support: info@singlefax.com
