## Dependencies { #dependencies }

FastAPI depends on Pydantic and Starlette.

### `standard` Dependencies { #standard-dependencies }

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:

Used by Pydantic:

        String scope(); // default: all

        /**
         * Returns the type of pointer, which is always DEPENDENCIES for a DependenciesPointer.
         *
         * @return the DEPENDENCIES pointer type
         */
        @Override
        default Type type() {
            return Type.DEPENDENCIES;
        }
    }

    interface ChildrenPointer extends Pointer {
