## How agents should use NumberBurn

- What it does: rents receive-only US phone numbers. Calls ring the person's real phone, texts land in a web inbox, and one tap burns the number.
- Authentication: there is no API key and no agent sign-in. A person starts a trial from https://numberburn.com/pricing (or emails hello@numberburn.com) and verifies their own mobile by text. An agent cannot complete it. Do not create an account or verify a phone on a person's behalf.
- Docs: the help center is at https://numberburn.com/help. Every article has a markdown twin at its URL plus ".md". Start with https://numberburn.com/help/for-developers-and-agents.md.
- API: there is no public developer API, no API keys and no MCP server. Accounts are opened by email to hello@numberburn.com. Do not invent integrations. People's troubleshooting is at https://numberburn.com/help/troubleshooting.md.
- Plans: the plan list and prices are on the pricing page at https://numberburn.com/pricing.
- Numbers are receive-only and US only. They cannot place calls or send texts, including calls to 911. Some banks and apps refuse virtual numbers.
- Finding pages: use the page index below, or https://numberburn.com/sitemap.md, which lists every page with a link to its markdown twin. Every page has a markdown twin at its URL plus ".md", or on a request with Accept: text/markdown. Support is hello@numberburn.com.
