Overview

EvoLink is an AI model API platform that provides access to 170+ LLM, image, video, and audio models from 30+ providers through a single unified API. It is designed for production apps, agents, and workflows, offering automatic failover, transparent pay-as-you-go pricing, and OpenAI-compatible integration. EvoLink is for developers and teams who need reliable, cost-efficient access to multiple AI models without managing separate provider accounts.

How it works

EvoLink acts as a model access layer. You sign up, create an API key, and choose an integration method compatible with OpenAI, Anthropic, or Google formats. Update your base URL and API key, and start calling models. The platform handles provider relationships, routing, and billing. Integration typically takes less than 10 minutes, and SDKs are available for Python, JavaScript, Go, and more.

Key capabilities

EvoLink offers automatic failover across providers, maintaining 99.9% uptime with <50ms routing overhead. Smart routing selects the fastest, cheapest, or most reliable endpoint in real time. The dashboard provides real-time usage and cost tracking, per-key analytics, and itemized usage records. Self-serve invoices with company title and e-seal are available. Volume discounts and dedicated support are offered for teams spending over $5,000/month.

Who it is for

EvoLink is built for developers, AI teams, and businesses shipping AI-powered applications to production. It suits teams building chat, reasoning, code generation, and agent workflows, as well as those generating video, images, and audio at scale. It is also useful for organizations that want to switch between model families without rewriting their stack, and for high-volume users seeking cost savings compared to official APIs.

Pricing and limits

EvoLink uses prepaid, pay-as-you-go pricing. You top up a credit balance (1 credit ≈ $0.0147, minimum top-up $10), and every API call deducts the exact cost: per token for LLMs, per image for image models, and per second for video and audio. Purchased credits never expire. Failed generations are not billed. There is no subscription, no seat fee, and no minimum monthly spend. Free credits are provided on signup without a credit card.
