Requests
A request is a HTTP request in the code block annotated language with http.
Example
```http
POST https://fakestoreapi.com/products HTTP/1.1
Content-Length: 125
Content-Type: application/json
{"title":"test product","price":13.5,"description":"lorem ipsum set","image":"https://i.pravatar.cc","category":"electronic"}
```Code fences
Both triple backticks and triple tildes are supported, with or without a language tag:
```http
GET https://api.example.com/ping HTTP/1.1
```
~~~http
GET https://api.example.com/ping HTTP/1.1
~~~Variable substitution
You can insert variables using `` placeholders. Missing variables cause a ParseError and abort execution.
* `base_url` = `"https://api.example.com"`
```http
GET /products/42 HTTP/1.1
Accept: application/json
```
