Codapi manages sandboxes (isolated execution environments) and provides an API to execute code in these sandboxes. It also provides a JavaScript widget [codapi-js](https://github.com/nalgeon/codapi-js) for easier integration.
Highlights:
- Supports dozens of playgrounds out of the box, plus custom sandboxes if you need them.
- Available as a cloud service and as a self-hosted version.

## Installation
See [Installing Codapi](docs/install.md) for details.
## Usage (API)
Call `/v1/exec` to run the code in a sandbox:
```http
POST https://api.codapi.org/v1/exec
content-type: application/json
{
"sandbox": "python",
"command": "run",
"files": {
"": "print('hello world')"
}
}
```
`sandbox` is the name of the pre-configured sandbox, and `command` is the name of a command supported by that sandbox. See [Configuration](docs/config.md) for details.
`files` is a map, where the key is a filename and the value is its contents. When executing a single file, it should either be named as the `command` expects, or be an empty string (as in the example above).
Response:
```http
HTTP/1.1 200 OK
Content-Type: application/json
{
"id": "python_run_9b7b1afd",
"ok": true,
"duration": 314,
"stdout": "hello world\n",
"stderr": ""
}
```
-`id` is the unique execution identifier.
-`ok` is `true` if the code executed without errors, or `false` otherwise.
-`duration` is the execution time in milliseconds.
-`stdout` is what the code printed to the standard output.
-`stderr` is what the code printed to the standard error, or a compiler/os error (if any).
## Usage (JavaScript)
See [codapi-js](https://github.com/nalgeon/codapi-js) to embed the JavaScript widget into a web page. The widget uses exactly the same API as described above.
