Does APIMart Support Streaming Responses?

Yes. APIMart's OpenAI-compatible endpoints support server-sent event (SSE) streaming for chat completion models. You can enable streaming by setting stream: true in your request payload, identical to how it works with the native OpenAI SDK — no additional configuration needed.

How Does APIMart's Automatic Failover Routing Work?

APIMart uses health-aware multi-provider routing. When a primary provider experiences latency spikes or downtime, the gateway automatically reroutes your request to a backup provider with the same model capabilities, maintaining response continuity without any code changes on your end.

Can APIMart Be Used With LangChain, LlamaIndex, Or Vercel AI?

Yes. APIMart is fully compatible with LangChain, LlamaIndex, Vercel AI SDK, and any framework built on OpenAI's Python, Node.js, Go, Java, PHP, C#, or Ruby client libraries. Migration requires only changing the base_url parameter to APIMart's endpoint.

How Are Async Video Generation Jobs Handled Via APIMart?

Video generation requests (e.g., Sora 2, Veo 3, Kling) are submitted as async tasks. APIMart returns a task ID immediately, which you can poll via the status endpoint. Webhook callbacks are also supported to notify your application when a video job completes, avoiding polling overhead.

What Is The llms.txt Feature And How Does It Help AI Agents?

APIMart exposes a machine-readable llms.txt documentation index at docs.apimart.ai/llms.txt. You can paste this URL into any AI agent (Claude, Codex, Cursor) as a single prompt, giving the agent instant structured knowledge of all APIMart models, endpoints, and parameters without manual documentation parsing.
