# api

```ts
const api: Apis
```

Built-in APIs used by Effection's runtime and host integrations.

Advanced integrations can decorate these APIs to observe or modify runtime
behavior within a scope.

### Examples
#### Example 1
```ts
import { main, useScope } from "effection";
import { api } from "effection/experimental";

await main(function* () {
  let scope = yield* useScope();

  scope.around(api.Scope, {
    create(args, next) {
      console.log("creating scope");
      return next(...args);
    },
  });
});
```
