Temp Mail API

Purpose: The API creates and manages temporary email addresses and lets users retrieve incoming messages programmatically.
Email handling: The API supports creating addresses, listing and retrieving messages, downloading attachments, reading message source, and deleting emails or messages.
Authentication: API requests require an API key in the X-API-Key header, and API access requires an active premium account.
Retention: API email addresses last up to 30 days, after which the emails are automatically deleted.
API limits: Monthly API request quotas depend on the subscription plan; the subscription page lists 1,000 API requests per month included.
Integrations: The maker lists email testing and CI/CD use cases, naming Playwright, GitHub Actions, Jenkins, and GitLab CI.
Libraries: Officially supported client libraries are listed for Golang, .NET, Node.js, PHP, and Python.
AI integrations: The remote MCP server connects the API to AI coding clients including Claude Code, Cursor, VS Code Copilot, Codex, and others, and requires an active premium account.
Security: The API page says requests use HTTPS encryption and email content is stored temporarily, then permanently deleted without backups after its retention period.
Privacy policy: The privacy policy says temp-mail.io does not store IP addresses and permanently deletes emails and temporarily stored data after their retention period.
Support: The maker directs users with questions or suggestions to [email protected].
Free access: The maker describes its temporary email service as free, while API access is a premium feature.
Trial and refund: The subscription page says there is no free trial and offers a refund within 30 days if the customer is not satisfied.
