3Min API

3Min API is an API relay service operated by Maverick Works in Seoul, South Korea. Users name an endpoint and define the fields they want to receive, then test it from a built-in console and invite collaborators by email, without writing backend code.

What It Is

3Min API is a backend-less API integration service. You enter a name and the data fields you want, and the service creates and hosts an endpoint for you. Every endpoint supports POST, GET, PUT, and DELETE. A built-in console lets you test how data arrives, and you can invite collaborators by email so they can start sending data to the endpoint.

Sharing and Delivery

Collaborators get their own dashboard with API keys, logs, and statistics. Both the owner and the collaborator can receive webhooks, and each delivery is signed so a receiving server can verify it. A polling API returns only the items that arrived since the last call, oldest first, and the caller sends back a cursor so it never has to track timestamps.

AI-Powered Management

The service connects to ChatGPT or Claude through an MCP integration, so endpoints can be managed through plain-language conversation. A Tasks feature lets the user ask the AI to have their own server (a worker) do a job, with the result returned into the chat. The site says signed delivery, progress updates, and retries are handled for it. A WordPress plugin embeds an API into a page with a shortcode.

Infrastructure and Reliability

The site states that traffic is encrypted with HTTPS/TLS, with DDoS filtering and sandbox/production API key separation. It describes a queue-first design that prevents data loss after an API call is accepted, a 3-tier auto-recovery system covering up to about 56 hours, and daily database backups with 7-day retention. It also says there are no per-second rate limits.
