Public Data API MVP Scaffolder

3.85

Derivation Chain

Step 1 Expansion of corporate public data utilization

→

Step 2 Tools to accelerate public data service development

→

Step 3 API selection → auto-generated boilerplate code + dashboard

Problem

Solo Entrepreneur developers building services with public data APIs spend 40-50% of their MVP development time (about 1 week out of 2-3) on repetitive boilerplate: API authentication setup, response parsing, error handling, and basic UI scaffolding. Each API has different auth methods and response formats, requiring fresh implementation every time.

Solution

Select desired APIs from the Public Data Portal and auto-generate Backend code with authentication, API calls, parsing, and error handling, plus a data visualization dashboard Frontend. Supports Python/Node.js, with one-click deployment to Vercel/Railway.

Target: Solo Entrepreneur developers and hackathon teams looking to rapidly prototype public data services; full-stack developers aged 20-30

Revenue Model: Premium: Free tier (1 API, basic templates), Pro 29,000 KRW (~$22)/month (unlimited APIs + custom dashboard + deployment integration), Per Transaction generation 1,500 KRW (~$1.10)

Ecosystem Role: Supplier

MVP Estimate: 2_weeks
