Frequently asked questions

Everything you need to know about Decisor

Our intelligent routing system analyzes each request and automatically selects the best AI provider based on task type, cost, and latency. For example, simple tasks might route to Groq for speed, while complex reasoning goes to Claude for quality.

Yes, absolutely. We use industry-standard encryption, never store your prompts or responses, and all API keys are encrypted. Your data flows directly through our secure infrastructure to the AI providers.

We have automatic failover built-in. If one provider is unavailable, requests automatically route to another provider. This ensures high availability and keeps your applications running smoothly.

Most customers save 70-90% on their AI API costs. Savings come from smart routing (choosing cheaper providers when appropriate), response caching (free repeated queries), and prompt optimization. You can see your exact savings in real-time in the dashboard.

Yes! Just change your API base URL from OpenAI to Decisor and use your Decisor API key. Everything else stays exactly the same - same request format, same response format. No code changes needed beyond the endpoint.

We currently support Groq, Together AI, and Fireworks AI. All providers offer ultra-low costs (5.5-12 cents per 1M tokens) and fast response times. We're constantly adding new providers based on customer demand.

Yes, you can set per-API-key spending limits to prevent cost overruns. You'll get alerts when you approach your limits, and requests will be blocked if you exceed them.

When you make an identical request (same model, same prompt), we return the cached response instantly at zero cost. This is perfect for repeated queries, testing, or common prompts. Cache duration is configurable per API key.

With Pro and Scale plans, you can create organizations and invite team members. All members share the same token pool and rate limits. You can assign roles (admin or member), manage API keys per organization, and track usage across your team. Perfect for agencies and development teams.
