# What is Orbit

> One API for Claude, GPT, Kimi and 50+ models. Routed to the cheapest healthy provider at Amazon Bedrock list rates.

Orbit is a single API for frontier models. You name a model, send an OpenAI- or Anthropic-shaped request, and Orbit routes it to the cheapest healthy path on Amazon Bedrock. There is no markup on token rates.

Use it when you want Claude, GPT, Kimi, Llama, Mistral, DeepSeek, Qwen, MiniMax and more without juggling provider accounts, SDKs, or failover logic.

## How it works

<Steps>
  <Step title="You pick a model">
    Use the public slug from the [catalogue](https://tryorbit.cloud/models) — for example `claude-sonnet-5`, `gpt-5-6-sol`, or `kimi-k2-5`.
  </Step>

  <Step title="Orbit routes the call">
    Before every request, Orbit checks price and live provider health, then sends the call down the cheapest healthy path. If a provider is degraded, the next healthy one serves it.
  </Step>

  <Step title="Credits are billed at list rates">
    Input and output tokens are charged at Amazon Bedrock list rates for that model. Orbit does not add a markup. Usage is logged on the organization.
  </Step>
</Steps>

## What you get

* **One `sk-orbit-` key** for every model in the catalogue
* **Drop-in SDKs** — official OpenAI and Anthropic clients, buffered or streamed
* **50+ models across 9 vendors**, served through Bedrock (including Bedrock Mantle for the newest GPT-5 models)
* **\$2 in free credits** on a new account, no card required
* **Dashboard** for keys, playground, usage, credits, and invoices

## Base URLs

| Surface          | Base URL                            | What the client appends        |
| ---------------- | ----------------------------------- | ------------------------------ |
| OpenAI SDK       | `https://api.tryorbit.cloud/api/v1` | `/chat/completions`, `/models` |
| Anthropic SDK    | `https://api.tryorbit.cloud/api`    | `/v1/messages`                 |
| Native Orbit API | `https://api.tryorbit.cloud/api/v1` | `/models/{slug}/chat`          |

<Tip>
  The OpenAI and Anthropic SDKs already know those extra path segments. Set only the base URL and your Orbit API key.
