--- meta: title: Get started with Meta Model API description: Build with Muse Spark on Meta Model API — your hub for the quickstart, capabilities, protocols, guides, and cookbook recipes. keywords: Meta Model API, Muse Spark, overview, quickstart, capabilities, cookbook cms: layout: large alias: /model-api/docs/overview target: aidmc --- # Get started with Meta Model API Meta Model API lets you build with Muse Spark using the tools you already run. It's drop-in compatible with the OpenAI SDK, the Anthropic SDK, and OpenAI-compatible agent CLIs. Point your client at the base URL, set your key, and keep the rest of your code. You get agent-ready primitives out of the box: parallel tool calls, streamed tool-call arguments, reasoning that carries across turns, and a 1M-token context window. ## At a glance {#at-a-glance} Everything you need to make your first call. | | | | --- | --- | | **Base URL** | `https://api.meta.ai/v1` | | **Model** | `muse-spark-1.1` | | **Context window** | 1,048,576 tokens | | **Auth** | Bearer token (`MODEL_API_KEY`) | | **Pricing** | Pay-as-you-go; see [Pricing and rate limits](/docs/pricing-rate-limits) | ## Explore the platform {#explore-the-platform} Jump to the surface you need. <tile-group col="3"> <tile color="elevated" icon="chain" href="/docs/quickstart" title="Quickstart"> Set your key, call the API, and read your first response.</tile> <tile color="elevated" icon="chain" href="/docs/models" title="Models"> Muse Spark specs: modalities, context window, and status.</tile> <tile color="elevated" icon="chain" href="/docs/cookbook" title="Cookbook"> Copy-paste recipes for primitives, agent loops, and use cases.</tile> <tile color="elevated" icon="chain" href="/docs/pricing-rate-limits" title="Pricing and rate limits"> Per-token pricing and the free and paid rate-limit tiers.</tile> <tile color="elevated" icon="chain" href="/docs/sdks" title="SDKs and libraries"> Wire up the OpenAI SDK, the Anthropic SDK, and compatible frameworks.</tile> <tile color="elevated" icon="chain" href="/docs/api-reference" title="API reference"> Full request and response schemas for every endpoint.</tile> </tile-group> ## Capabilities {#capabilities} Muse Spark ships agent-ready primitives.
