Defapi - Unified AI Model API

Can I route requests to different AI models through a single API endpoint?

Yes. Defapi provides unified API access to models from OpenAI, Anthropic, Google, and other providers, so you can call different models through one interface instead of managing separate vendor integrations. The platform includes intelligent routing that can automatically direct requests to the most cost-effective model for your use case.

What models are available and how much does each one cost?

Defapi uses pay-per-use pricing and lists costs for models including Claude Opus 4.8 ($2.50/$12.50), GPT-5.5 ($2.50/$15), Claude Fable 5 ($5/$25), and specialized models like GPT-Image-2 ($0.02 per request) and Grok Imagine Video ($0.014 per second). Check their pricing page for the current full list of available models and rates, as these may change.

Does Defapi offer a free tier or trial before I pay?

Defapi operates on a freemium model with pay-per-use pricing, but the details of what free access or trial period it provides are not published on their site. Contact them directly to understand the free tier boundaries before you commit to integration.

Can I monitor API usage and costs in real time?

Yes. Defapi includes real-time monitoring and usage statistics so you can track consumption across models. The platform also provides detailed performance monitoring, which helps you understand how the intelligent routing is optimizing your spend across different providers.
