A more professional 4SAPI alternative
4SAPI plays a lightweight price-war strategy but lacks enterprise support, SLAs, and compliance posture. AICodeDog keeps competitive relay pricing while delivering enterprise-grade stability and a professional team — a better fit for long-running production scenarios.

Stable, transparent, and consistent developer experience — the prerequisite for shipping AI into production.
- Transparent relay pricing · clear savings ratio

AICodeDog vs 4SAPI · FAQ
Do I need to change code when migrating from 4SAPI to AICodeDog?+
Almost nothing. AICodeDog exposes an OpenAI-compatible API — swap the base_url and api_key and you are done. Streaming, function_call, tools and other advanced capabilities all carry over.
How is AICodeDog priced?+
Source-code delivery is US$1,688 and managed setup is US$1,999. Hosted API relay access is usage-based; each model page shows the active rate and billing unit before you call it.
Are failed calls charged?+
No. AICodeDog only bills when the upstream returns a complete successful response. Timeouts, rate limits, and upstream errors do not consume balance.

Yes. Independent sub-domains, brand customisation, sub-account systems, and separate billing — built for resellers and integrators reselling onward.
