Public API Quality Certification Badge

2.85

Derivation Chain

Step 1 Korea ranks #1 in digital government, but public data reuse systems need improvement
→
Step 2 Need for public data API quality standardization
→
Step 3 Public data API quality auto-measurement service
→
Step 4 API quality certification badge Platform

Problem

Startups looking to integrate public data APIs have no criteria to determine which of 2,000+ APIs are stable and high-quality, resulting in a 35% post-adoption service disruption rate due to API instability. On the provider side, government agencies also lack objective measures of their own API quality, making it difficult to prioritize improvements.

Solution

Automatically measures public data API response speed, availability, documentation quality, and data freshness, assigning grades (A–F) and issuing certification badges. Core features: (1) automated API quality measurement (response time, uptime, error rate, documentation completeness), (2) grade-based certification badges and quality reports, (3) quality improvement recommendation dashboard for API provider agencies.

Target: CTOs at Startups using public data APIs; data officers at government agencies providing data.go.kr APIs
Revenue Model: Premium: Free (monthly quality Report access), Startup $29/mo (real-time monitoring + alerts), Agency $149/mo (improvement recommendations + custom reports)
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
