About EvoLink

EvoLink is a unified AI model API that fronts more than seventy-five production models across four modalities behind one key and an OpenAI-compatible interface. The catalog splits into video, image, LLM, and audio. Video covers Veo 3.1 with native audio, Seedance 2.0 for cinematic shots with camera control, Wan 2.6 for text-to-video with built-in speech and music, and MiniMax H3 (Hailuo 3); image covers GPT Image 2, Seedream 5.0, and Nano Banana 2; the LLM side lists GPT 5.5, Claude 4.7, Gemini 2.5 Pro, and Kimi K2 among others; audio covers Suno for full-track music generation. The vendor draws a deliberate line between itself and price-cut aggregators, arguing that its value is documented model surfaces — capabilities, docs, and unit prices visible before you integrate — rather than mystery wrappers. The Smart Router is the operational piece: a single request is routed in real time to the fastest, cheapest, or most reliable provider endpoint with automatic failover, with the vendor claiming under 50ms routing overhead and 99.9% uptime. Billing is worth understanding precisely. There is no subscription and no seat fee; you top up prepaid credits (minimum $10, credits never expire, auto-recharge available, and card, Alipay/WeChat Pay, or corporate bank transfer accepted) and each call meters against the balance — video and audio per second, images per image, LLMs per token. Failed generations are never billed. Per-key usage analytics, cost breakdown by model, itemized records, and self-serve invoices are in the dashboard.
