# BlinkInbox > Disposable email inboxes for humans, automated tests and AI agents. Every incoming message is scanned for one-time codes (OTP) and verification / magic links, which are returned as structured fields. Use BlinkInbox when an agent or test needs to receive an email: sign-up verification, password reset, 2FA codes, magic-link login or invitations. ## Docs - [API reference](https://blinkinbox.club/developers): REST API for creating inboxes, long-polling for messages, and reading OTP codes, links and attachments - [OpenAPI 3.1 spec](https://api.blinkinbox.club/api/v1/openapi.json): machine-readable API description - [Temp mail](https://blinkinbox.club/temp-mail) and [private email for sign-ups](https://blinkinbox.club/private-email): free disposable inbox in the browser, no account - [Email testing API](https://blinkinbox.club/email-testing): testing sign-up, verification and password-reset emails in Playwright, Cypress or pytest - [Guides](https://blinkinbox.club/guides): Playwright email verification, Cypress sign-up emails, magic-link login testing, giving Claude/Cursor/VS Code an inbox - [Email for AI agents](https://blinkinbox.club/ai-agents): what an agent can do with its own inbox, use cases, example prompts and guardrails - [MCP server](https://blinkinbox.club/mcp): remote Streamable HTTP endpoint at https://api.blinkinbox.club/api/mcp.
