Mizumi
Official OpenAI & Gemini API, 10–20% below list
Mizumi is an OpenAI-compatible gateway serving official OpenAI and Gemini deployments at 10–20% below list price. Credits never expire. Unused balance refundable within 14 days. One key, one endpoint — no cloud accounts, no billing setup. $3 free to start.
Hi Product Hunt 👋
I'm Laurence, founder of Mizumi. Quick story on why this exists:
I kept burning money on AI API resellers whose credits expired in 30 days, whose "discount models" turned out to be repackaged, and whose pricing had no anchor to anything real.
So we built the gateway we wanted to buy from:
→ Official OpenAI + Gemini deployments only — same models, full context, no quantization
→ Prices anchored to published list price: 10% off at Starter, up to 20% off at Scale (lifetime-spend tiers, automatic)
→ Credits never expire. Unused balance refundable within 14 days, no questions
→ One OpenAI-compatible endpoint — works with Cherry Studio, Cline, Roo Code, Codex CLI, LangChain out of the box
→ $3 free credit, no card required
We're a tiny team and we read everything. What would make this a no-brainer for your stack? What models should we add next (Claude is on the roadmap)?
