Quick thesis
Start with a small API aggregation tool for developers who need lower-cost, multi-model, OpenAI-compatible access.
Do these 3 things today
- Pick three target users: indie developers, small teams, AI tool operators.
- Run an OpenAI-compatible endpoint with DeepSeek + Qwen + Gemini/Groq via LiteLLM.
- Write one setup guide for Chatbox/Cursor and recruit 20 testers.
Why now
- Model prices are falling while integration complexity grows.
- Search intent around API relay, free API, and OpenAI compatibility is explicit.
- Open-source proxy tools make a lightweight MVP feasible.
- Teams increasingly care about cost attribution, logs, rate limits, and compliance.
Best for / not for
Best for
- Solo builders comfortable with backend/API work
- Creators with developer distribution
- Operators who can maintain provider reliability
Not for
- Non-technical founders without a technical partner
- People who only want a one-off content site
- Builders unwilling to handle abuse, risk, and payments
Validation signals
- 10 developers are willing to move one model call to your unified key.
- The first week generates at least 1,000 real API calls, not just bookmarks.
- Someone pays a small amount for stable credits, regional access, or usage tracking.
Pitfalls
- Do not integrate too many providers first; make 2-3 stable.
- Do not promise unlimited free access; sell reliability, transparent billing, and fallback.
- Add rate limits, logs, and abuse controls early or costs can explode.
7-day MVP path
- Day 1: choose three providers: DeepSeek, Qwen, Gemini/Groq.
- Day 2: build an OpenAI-compatible proxy with LiteLLM or custom code.
- Day 3: add API keys, usage tracking, and rate limits.
- Day 4: connect payments or manual credits.
- Day 5: publish five tutorial pages for search demand.
- Day 6: recruit 20 developer testers and log failures.
- Day 7: publish reliability/pricing rankings and convert first users.
Tool stack
First users
- Publish free API comparison and one-key setup tutorials in developer communities.
- Create one-click templates for Cursor, Claude Code, and Chatbox users.
- Recruit builders of mini apps, Chrome extensions, and content tools.
Monetization
- Usage markup of 5-15%
- Monthly plans: $9/$29/$99
- Enterprise private deployment and compliance logs
- Affiliate or lead-gen from tutorials
