# Overview

> Base URLs, keys, and model IDs for the local inference API.

Magnitude serves an HTTP API on port `10100` while it is running. **Connections** uses it to configure supported agents. Any other OpenAI-compatible or Anthropic-compatible client can use it directly.

## Base URLs

| Client type          | Base URL                                     |
| -------------------- | -------------------------------------------- |
| OpenAI-compatible    | `http://127.0.0.1:10100/inference/v1`        |
| Anthropic-compatible | `http://127.0.0.1:10100/inference/anthropic` |

Clients append their own paths, such as `/chat/completions` or `/v1/messages`. If a client asks for a full endpoint URL instead, use the paths in [Endpoints](/api/endpoints).

From another device, replace `127.0.0.1` with the address shown under **Reachable at** in **Settings → Network access**. See [Other devices](/api/other-devices).

## API keys

| Caller        | Key                                                                                                  |
| ------------- | ---------------------------------------------------------------------------------------------------- |
| This computer | None required. If the client insists on a value, any value works.                                    |
| Other devices | The key from **Settings → Network access**, sent as `Authorization: Bearer KEY` or `x-api-key: KEY`. |

## Model IDs

List the models available for inference:

```sh theme={"theme":{"light":"github-light","dark":"github-dark"}}
curl http://127.0.0.1:10100/inference/v1/models
```

Use the exact `id` from the response as the model name in requests. Display names are not accepted. Magnitude loads the model on the first request, which takes longer than later requests.

## Scope

The API provides inference only: listing models and generating text. Downloading models, managing them, and the Magnitude app itself are not available over the API.

Opening `http://127.0.0.1:10100` in a browser shows a short text summary of these paths.
