AI Model API Platform for Production

EvoLink is an AI model API platform. You can access 120+ models from 20+ providers — including GPT, Claude, Gemini, Seedance, Veo, and Suno — through one EvoLink API. Browse models, compare pricing, read docs, get an API key, and start calling models for production apps, agents, and workflows.

EvoLink uses transparent pay-as-you-go pricing. You only pay for what you use, calculated per token, image, or video second depending on the model. View model pricing on our pricing page before you call. No monthly minimums, no setup costs, and new users get free credits to test.

Integration typically takes less than 10 minutes. If you're already using OpenAI or similar APIs, you just need to change your base URL and API key. Our API is compatible with OpenAI's format, so most existing code works without modification. We provide SDKs for Python, JavaScript, Go, and more, plus comprehensive documentation and migration guides.

EvoLink supports 120+ models from leading providers including OpenAI (GPT-4o, GPT-Image), Anthropic (Claude 4 Sonnet, Opus), Google (Gemini 2.5, Veo 3), BytePlus (Seedance, Seedream), and more. We continuously add new models and providers. All models are accessible through our unified API endpoint, so you can switch models with a single parameter change.

No, your application stays online. EvoLink provides automatic failover across multiple providers. If OpenAI experiences an outage, we instantly route your requests to alternate providers like Anthropic or Google. Our system maintains 99.9% uptime by monitoring provider health in real-time and pre-emptively routing away from degraded services. You get reliability that's impossible with a single provider.

EvoLink adds minimal latency (typically <50ms) while often improving overall response time. Our intelligent routing selects the fastest available provider based on real-time performance metrics. Many users actually experience faster responses because we route around congested providers and use geographic optimization. Our infrastructure is deployed globally across AWS, ensuring low latency worldwide.

Your data security is our top priority. EvoLink acts as a secure proxy and does NOT store your prompts or responses. All data is encrypted in transit using TLS 1.3. We maintain detailed audit logs for compliance but never log sensitive content. Your data stays yours.

You only need one EvoLink key - we handle all provider relationships for you. This means less security risk (fewer keys to manage), simplified billing (one invoice), and instant access to new providers without additional setup. Your EvoLink key works across all supported models and providers.

EvoLink offers key advantages: 1) Access 120+ models from 20+ providers through one API, 2) Automatic failover for 99.9% uptime, 3) Clear, transparent pricing across all models, 4) Unified billing and usage analytics, 5) Flexible model choices - switch models without code changes. Direct provider access can't match our reliability, model variety, or convenience.
