# Sandbox Egress Forward Post

`POST /api/egress/p/{alias}/{upstream_path}`

## Request

- Base URL: `https://app.thinqos.com` (the document declares no server; this is the origin it was published from)
- URL: `https://app.thinqos.com/api/egress/p/{alias}/{upstream_path}`
- Auth: none declared

Authenticate, resolve, inject, forward, stream back.

``payload`` here is the SAME verification ``bounded_request_body`` already
forced to happen before ``body`` could be produced above; FastAPI's
per-request dependency cache means this does not verify the token a
second time, it just hands back the one result.

## Path parameters

- `alias` string, required
- `upstream_path` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
