pandoraspec 0.2.0

DORA Compliance Auditor for OpenAPI Specs

PanDoraSpec

The Open DORA Compliance Engine for OpenAPI Specs.

PanDoraSpec is a CLI tool that performs deep technical due diligence on APIs to verify compliance with DORA (Digital Operational Resilience Act) requirements. It compares OpenAPI/Swagger specifications against real-world implementation to detect schema drift, resilience gaps, and security issues.

📦 Installation

pip install pandoraspec

System Requirements

The PDF report generation requires weasyprint, which depends on Pango.

macOS:

brew install pango

Debian / Ubuntu:

sudo apt-get install libpango-1.0-0 libpangoft2-1.0-0

🛠️ Development Setup

To run the CLI locally without reinstalling after every change:

1. Clone & CD:

git clone ...
cd pandoraspec

2. Create & Activate Virtual Environment: It's recommended to use a virtual environment to keep dependencies isolated.

python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Editable Install:

pip install -e .

This links the pandoraspec command directly to your source code. Any changes you make will be reflected immediately.

🚀 Usage

Run the audit directly from your terminal.

Basic Scan

pandoraspec https://petstore.swagger.io/v2/swagger.json

With Options

pandoraspec https://api.example.com/spec.json --vendor "Stripe" --key "sk_live_..."

Local File

pandoraspec ./openapi.yaml

🏎️ Zero-Config Testing (DORA Compliance)

For standard DORA compliance, you simply need to verify that your API implementation matches its specification. No configuration is required.

pandoraspec https://petstore.swagger.io/v2/swagger.json

This runs a fuzzing audit where random data is generated based on your schema types (e.g., sending random integers for IDs).

• Value: This is sufficient to prove that your API correctly handles unexpected inputs and adheres to the basic contract (e.g., returning 400 Bad Request instead of 500 Server Error).
• Limitation: Detailed business logic requiring valid IDs (e.g., GET /user/{id} where {id} must exist) may return 404 Not Found. This is acceptable for a compliance scan but may not fully exercise deeper code paths.

🧠 Advanced Testing with Seed Data

To test specific business workflows (e.g., successfully retrieving a user profile), you can provide "Seed Data". This tells PanDoraSpec to use known, valid values instead of random fuzzing data.

pandoraspec https://petstore.swagger.io/v2/swagger.json --config seed_parameters.yaml

Configuration Hierarchy

You can define seed values at three levels of specificity. The engine resolves values in this order: Endpoints > Verbs > General.

seed_data:
  # 1. General: Applies to EVERYTHING (path params, query params, headers)
  general:
    username: "test_user"
    limit: 50

  # 2. Verbs: Applies only to specific HTTP methods (Overwrites General)
  verbs:
    POST:
      username: "admin_user" # Creation requests use a different user

  # 3. Endpoints: Applies only to specific routes (Overwrites Everything)
  endpoints:
    /users/me:
      GET:
        limit: 10

🔗 Dynamic Seed Data (Chaining Requests)

You can even test dependency chains where one endpoint requires data from another (e.g., get a User ID from a search result to query their profile).

Supported Features:

• Dynamic Resolution: Fetch a value from another API call before running the test.
• Extraction: Extract values from JSON responses or plain text.
• Parameter Interpolation: Use {param} in the dependency URL to chain multiple steps.

endpoints:
  /user/{username}:
    GET:
      username:
        # 1. Fetch the user list first
        # 2. Extract the 'username' field from the response
        from_endpoint: "GET /users/search?role=admin"
        extract: "data.items.0.username"

  /orders/{orderId}:
    GET:
      orderId:
        # 1. Use the {userId} from our general seeds
        # 2. Call /users/{userId}/latest-order
        # 3. Extract the ID using Regex from a message string
        from_endpoint: "GET /users/{userId}/latest-order"
        extract: "message"
        regex: "Order ID: ([0-9]+)"

🛡️ What It Checks

Module A: The Integrity Test (Drift)

Checks if your API implementation matches your documentation.

• Why? DORA requires you to monitor if the service effectively supports your critical functions. If the API behaves differently than documented, it's a risk.

Module B: The Resilience Test

Stress tests the API to ensure it handles invalid inputs gracefully (4xx vs 5xx).

• Why? DORA Article 25 calls for "Digital operational resilience testing".

Module C: Security Hygiene

Checks for common security headers and configurations.

Module D: The Report

Generates a PDF report: "DORA ICT Third-Party Technical Risk Assessment".
