APIMart

APIMart is a commercial API aggregator that exposes a unified, OpenAI-compatible endpoint for chat, image, video, and audio models from providers including OpenAI, Anthropic, Google, ByteDance, Qwen, Kimi, and MiniMax. The core workflow is minimal: sign up, generate an API key from the dashboard, point your existing OpenAI SDK at APIMart’s base URL, and your application gains access to the full catalog without per-provider onboarding. The vendor states you pay only for successful requests, and per-model pricing is displayed with explicit before-and-after figures showing the discount applied.

The standout differentiator is breadth-plus-discount on a single credential. The vendor advertises 500-plus models and prices at 30–70 percent below official provider rates, visible at the model level in the marketplace. For teams that prototype across categories — spinning up a text pipeline on GPT-5, an image workflow on Imagen 4.0, and a video task on Sora 2 in the same sprint — APIMart removes the overhead of separate accounts, keys, and billing reconciliation for each.

APIMart fits tightly scoped integration work: you control the model selection logic, APIMart handles the routing and billing. That boundary is also the constraint. The gateway is passive — it does not autonomously retry failed calls, fall back to a cheaper model when quota is hit, or route based on latency. Any of that logic lives in your application code. Teams that need the gateway itself to make routing decisions, or who require self-hosted deployment for data-residency compliance, will hit that wall and look elsewhere. There is no self-hosted option per the vendor page.
