Unlimited, sustainably. Switch once. Keep building. 0code is sustainably unlimited and will always be free. Why switch to 0code? One request, no SDK. Call GET /api/chat/ from any language, script, or prototype. During high usage, the same request returns a queue ID while it finishes safely in the background. No single-provider dead end. Provider quotas, outages, and busy models are handled with automatic fallback. Fast by default. 0code learns which available models respond fastest and quietly prefers them. No lock-in. You use one stable endpoint instead of rewriting your app around each provider's API. Sustainable by design. 0code routes around provider limits instead of repeatedly leaning on one API, while lightweight bot protection keeps shared capacity available for real users. Free for everyone. 0code will always be free, without the hard request limits common elsewhere.
