3Min API turns schema definitions into production-ready API endpoints instantly. Unlike traditional backends that take weeks to build, you define your data fields and get a fully working CRUD API with automatic validation, webhook delivery, and payload archiving โ all in 3 minutes. There are no per-second rate limits, so your API handles sudden traffic spikes seamlessly, backed by queues and automatic retry for reliability.
Unlike Airtable or Supabase, 3Min API is purpose-built for receiving and relaying data from external partners. Collaboration keys let you share API access instantly, with separate sandbox and production environments. There's no database setup, no deployment, and no backend code to write.
Small businesses and solo developers who need to receive data via API but don't have a backend team. This includes small e-commerce companies, early-stage startups, and marketing agencies managing partner integrations.
We kept hearing the same request from small businesses: "We don't have a backend team, but our client wants an API." Every time, it required weeks of custom development. We built 3Min API to solve this โ making it possible in 3 minutes instead of 3 weeks.
