🎯 Executive Summary

ApexRestpy is a lightweight, minimal-dependency (only requests) client library that enables Python applications to communicate swiftly with Oracle APEX RESTful services. It is a direct Python adaptation of the ApexBridge library written in C++ for microcontrollers (ESP32/ESP8266); you can use the same logical API on servers, Raspberry Pi, automation scripts, and CI/CD pipelines.

The library abstracts Oracle APEX's standard /<base_path>/<schema>/<module>/<resource> URL structure and provides Bearer token authentication, query parameter management, and all HTTP methods (GET/POST/PUT/PATCH/DELETE) through a unified, easy-to-test interface. HTTPS connections are established with zero configuration; SSL certificate management is handled entirely and automatically by requests + certifi.

Target audience: Python developers using Oracle APEX as a backend, IoT integration engineers, and embedded systems developers migrating from the Arduino ecosystem to Python.

🏗️ Architecture & Flow

ApexRestpy acts as a thin abstraction layer between your application and the Oracle APEX server:

[!NOTE] As a library, the only runtime dependency is requests. No Docker or other infrastructure tooling is required.

---

🚀 Installation

From PyPI (Recommended)

pip install apex-restpy

Development Setup

# 1. Clone the repository
git clone https://github.com/AtaCanYmc/ApexRestpy.git
cd ApexRestpy

# 2. Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate        # Linux / macOS
# .venv\Scripts\activate.bat     # Windows CMD
# .venv\Scripts\Activate.ps1     # Windows PowerShell

# 3. Install the package with development dependencies
pip install -e ".[dev]"

Verify Installation

python -c "from apex_restpy import ApexBridge; print('✅ apex-restpy is ready!')"

---

⚡ Quick Start

from apex_restpy import ApexBridge

# 1. Initialise the bridge
bridge = ApexBridge(schema="myschema")

# 2. (Optional) Set the authentication token
bridge.set_token("your-jwt-bearer-token")

# 3. Prepare the endpoint and send a request
bridge.prepare_url("time", "now")
response = bridge.send_request()   # default: GET

# 4. Use the response
print(response["full_timestamp"])  # → "2025-03-02T14:30:00"
print(response["year"])            # → 2025

---

📖 Usage & API Reference

ApexBridge(schema, base_path, host, timeout, debug, session)

The core client class. All APEX communication is handled through this object.

bridge = ApexBridge(
    schema="myschema",          # APEX workspace schema name (required)
    base_path="/pls/apex",      # URL prefix (default: "/pls/apex")
    host="apex.oracle.com",     # APEX server address (default)
    timeout=10.0,               # Request timeout in seconds (default: 10)
    debug=False,                # If True, enables DEBUG log level
)

---

set_token(token: str)

Enables Bearer token authentication. The Authorization: Bearer <token> header is automatically added to all subsequent requests.

bridge.set_token("eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...")

[!NOTE] The token must be longer than 1 character (exact compatibility with the C++ original). If an empty string is provided, the header is not added.

---

prepare_url(module, resource, schema=None) → str

Constructs the APEX REST endpoint path and stores it in the internal _last_endpoint.

url = bridge.prepare_url("sensor", "data")
# → "/pls/apex/myschema/sensor/data"

# With a different schema
url = bridge.prepare_url("time", "now", schema="otherschema")
# → "/pls/apex/otherschema/time/now"

---

add_parameter(param, value, url=None) → str

Appends a query parameter to the active endpoint (or a given URL).

bridge.prepare_url("sensor", "data")
bridge.add_parameter("id", "42")       # → ...?id=42
bridge.add_parameter("type", "temp")   # → ...?id=42&type=temp

# On a custom URL (the stored endpoint is not modified)
result = bridge.add_parameter("limit", "10", url="/pls/apex/myschema/items/list")
# → "/pls/apex/myschema/items/list?limit=10"

---

add_path(path, url=None) → str

Appends an additional path segment to the active endpoint.

bridge.prepare_url("items", "list")
bridge.add_path("active")
# _last_endpoint → "/pls/apex/myschema/items/list/active"

---

send_request(method="GET", payload=None, url=None) → dict

Sends an HTTP request and returns the JSON response as a dict.

# GET
response = bridge.send_request()

# POST — with a JSON body
response = bridge.send_request(
    method="POST",
    payload={"sensor_id": "42", "value": 23.5},
)

# PUT, PATCH, DELETE
bridge.send_request("PUT",   payload={"name": "updated"})
bridge.send_request("PATCH", payload={"status": "active"})
bridge.send_request("DELETE")

# Request to a different URL (the stored endpoint is not modified)
response = bridge.send_request("GET", url="/pls/apex/myschema/custom/path")

Supported methods: GET · POST · PUT · PATCH · DELETE

---

Exceptions

Exception	When raised
ApexConnectionError	Network connection cannot be established or times out
ApexResponseError	Response body is not valid JSON
ValueError	An unsupported HTTP method is provided

from apex_restpy import ApexBridge, ApexConnectionError, ApexResponseError

try:
    response = bridge.send_request()
except ApexConnectionError as e:
    print(f"Connection error: {e}")
except ApexResponseError as e:
    print(f"Invalid response: {e}")

---

Full Scenario Example

from apex_restpy import ApexBridge

bridge = ApexBridge(schema="iot_prod", timeout=15.0, debug=True)
bridge.set_token("your-jwt-token")

# Fetching data with pagination and filtering
bridge.prepare_url("sensors", "readings")
bridge.add_parameter("device_id", "esp32-01")
bridge.add_parameter("limit", "100")
bridge.add_path("latest")
# → /pls/apex/iot_prod/sensors/readings/latest?device_id=esp32-01&limit=100

response = bridge.send_request("GET")

for reading in response.get("items", []):
    print(f"{reading['ts']} → {reading['value']} {reading['unit']}")

---

🔐 Environment Variables

ApexRestpy is a library, not a CLI tool or service, so it does not ship its own .env file. For applications that use credentials, we recommend the following pattern:

.env.example — Reference this file in your project:

# Oracle APEX Configuration
APEX_SCHEMA=your_schema_name
APEX_BASE_PATH=/pls/apex
APEX_HOST=apex.oracle.com
APEX_TIMEOUT=10

# Authentication
APEX_BEARER_TOKEN=your_jwt_or_oauth_token

Usage:

import os
from dotenv import load_dotenv
from apex_restpy import ApexBridge

load_dotenv()

bridge = ApexBridge(
    schema=os.environ["APEX_SCHEMA"],
    host=os.environ.get("APEX_HOST", "apex.oracle.com"),
    timeout=float(os.environ.get("APEX_TIMEOUT", "10")),
)
bridge.set_token(os.environ["APEX_BEARER_TOKEN"])

[!CAUTION] Never commit your .env file to Git. Our .gitignore already excludes it.
