apyr 
apyr (all lowercase) is a simple & easy to use mock API server.
It's great for front-end development when your API is not ready, or when you are prototyping an API. It's also very useful for demos & hackathons.

Port can be set by -p PORT. The default port is 8000.

Example endpoints.yaml
# A GET method that returns a list of employees.
- method: GET
path: test/employees
status_code: 200
content: >
[
{ "first_name": "Peter", "last_name": "Venkman" },
{ "first_name": "Ray", "last_name": "Stantz" },
{ "first_name": "Egon", "last_name": "Spengler" },
]
# A GET method that returns an employee.
# Take note of the two %functions%- the employee's first name, last name and age will be random at every response.
- method: GET
path: test/employee/2
status_code: 200
content: >
{
"first_name": "%random_first_name(female)%",
"last_name": "%random_last_name()%",
"age": %random_int(20, 50)%
}
# A POST method that returns a 500. Great for testing error pages.
- method: POST
path: test/employee
media_type: text
status_code: 500
content: An unexpected error occured while creating the employee.
# A PUT method that returns a 201. Does not return a body- content is optional.
- method: PUT
path: test/employee/3
status_code: 201
# A GET method that returns an HTML page.
- method: GET
path: test/help
status_code: 200
media_type: text/html
content: >

Ghostbusters, whaddya want.
# The same method as above, but the content is referenced from another file. Path is relative to project root.
- method: GET
path: test/help2
status_code: 200
media_type: text/html
content_path: assets/help.html
Example usage
An example of making a curl request to our second endpoint defined above:
~ λ curl 0.0.0.0:8000/test/employee/2 -v
> GET /test/employee/2 HTTP/1.1
>
< HTTP/1.1 200 OK
< server: uvicorn
< content-length: 52
< content-type: application/json
<
{ "first_name": "Geoffrey", "last_name": "Greeley", "age": 28 }
No need to restart apyr after editing endpoints.yaml- it's all taken care of!
