Flask JSON-RPC

Basic JSON-RPC implementation for your Flask-powered sites.

Some reasons you might want to use:

Simple, powerful, flexible, and pythonic API.
Support JSON-RPC 2.0 version.
Support Python 3.9 or later.
Experimental support to Mypyc, it compiles Python modules to C extensions.
The web browsable API.
Run-time type checking functions defined with PEP 484 argument (and return) type annotations.
Extensive documentation, and great community support.

There is a live example API for testing purposes, available here.

Getting Started

Create your application and initialize the Flask-JSONRPC.

from flask import Flask
from flask_jsonrpc import JSONRPC

app = Flask("application")
jsonrpc = JSONRPC(app, "/api", enable_web_browsable_api=True)

Write JSON-RPC methods.

@jsonrpc.method("App.index")
def index() -> str:
    return "Welcome to Flask JSON-RPC"

All code of example run.py.
