Getting Started with the OpenClaw Rating API SDK

The OpenClaw Rating API SDK provides a ready‑to‑use library that lets developers add robust rating functionality—such as star, thumbs‑up/down, or custom score systems—to any application with just a few lines of code.

1. Introduction

Rating systems are a cornerstone of user‑generated feedback, influencing product decisions, content ranking, and personalization engines. The OpenClaw Rating API abstracts the heavy lifting of data storage, aggregation, and security, allowing you to focus on the user experience. This guide walks you through everything a software developer or API integrator needs to get started: from prerequisites and installation to authentication, request patterns, response handling, and best‑practice design patterns.

2. Prerequisites

• Node.js ≥ 14 or Python ≥ 3.8 (the SDK is available for both environments).
• An active UBOS account to obtain API credentials.
• Basic knowledge of RESTful APIs and JSON handling.
• Optional: Workflow automation studio if you plan to chain rating events with other business processes.

If you are new to UBOS, the About UBOS page offers a quick overview of the platform’s mission and ecosystem.

3. Installing the OpenClaw Rating API SDK

Installation differs slightly between Node.js and Python. Choose the language that matches your stack.

npm install @ubos/openclaw-rating-sdk

pip install ubos-openclaw-rating

Both packages expose a unified client object that handles request signing, retries, and response parsing. After installation, you can import the client as shown below.

// Node.js example
const { OpenClawClient } = require('@ubos/openclaw-rating-sdk');

# Python example
from ubos_openclaw_rating import OpenClawClient

4. Setting Up Authentication

The SDK uses API keys issued from the UBOS dashboard. Navigate to UBOS pricing plans to select a tier that includes the OpenClaw service, then generate a public key and a secret key**.

Store these credentials securely—environment variables are the recommended approach.

// Node.js – .env
OPENCLAW_PUBLIC_KEY=your_public_key
OPENCLAW_SECRET_KEY=your_secret_key

# Python – .env
OPENCLAW_PUBLIC_KEY=your_public_key
OPENCLAW_SECRET_KEY=your_secret_key

Initialize the client with these variables:

// Node.js
const client = new OpenClawClient({
  publicKey: process.env.OPENCLAW_PUBLIC_KEY,
  secretKey: process.env.OPENCLAW_SECRET_KEY,
});

# Python
client = OpenClawClient(
    public_key=os.getenv('OPENCLAW_PUBLIC_KEY'),
    secret_key=os.getenv('OPENCLAW_SECRET_KEY')
)

Authentication is performed automatically on each request via HMAC‑SHA256 signing, so you never need to manually attach tokens.

5. Making Rating Requests

Once authenticated, you can submit rating events. The SDK supports three primary methods:

1. createRating – Record a new rating.
2. updateRating – Modify an existing rating.
3. getAggregatedScore – Retrieve the average or weighted score for a resource.

Below is a complete Node.js example that records a 4‑star rating for an article identified by articleId:

async function submitRating() {
  try {
    const response = await client.createRating({
      resourceId: 'article-12345',
      userId: 'user-987',
      score: 4,
      metadata: { source: 'mobile-app' }
    });
    console.log('Rating saved:', response.data);
  } catch (err) {
    console.error('Error submitting rating:', err);
  }
}
submitRating();

Python developers enjoy a similar flow:

def submit_rating():
    try:
        response = client.create_rating(
            resource_id='article-12345',
            user_id='user-987',
            score=4,
            metadata={'source': 'web-portal'}
        )
        print('Rating saved:', response.data)
    except Exception as e:
        print('Error submitting rating:', e)

submit_rating()

Both snippets automatically serialize the payload to JSON, sign the request, and handle HTTP retries.

6. Handling API Responses

The SDK returns a standardized response object containing status, data, and error fields. Successful calls have status === 200 and a data payload; failures populate error with a descriptive message and an HTTP status code.

// Example response handling (Node.js)
if (response.status === 200) {
  const { ratingId, createdAt } = response.data;
  console.log(`Rating ${ratingId} stored at ${createdAt}`);
} else {
  console.warn('API error:', response.error.message);
}

Common error scenarios include:

• 401 Unauthorized – Invalid API keys or signature mismatch.
• 400 Bad Request – Missing required fields (e.g., resourceId).
• 429 Too Many Requests – Rate‑limit exceeded; implement exponential back‑off.

For robust production code, wrap calls in a retry utility. The Workflow automation studio can orchestrate retries and alerting without writing extra code.

7. Best‑Practice Patterns

Adopting proven patterns reduces bugs and improves scalability. Below are the top five recommendations for integrating the OpenClaw Rating API.

Following these patterns ensures that your rating feature remains performant, secure, and easy to maintain.

8. Embedding the Internal Link

When you host the OpenClaw service on UBOS, you benefit from built‑in scaling, monitoring, and billing. The dedicated hosting page—OpenClaw hosting on UBOS—provides step‑by‑step instructions, pricing details, and a one‑click deployment button. Embedding this link in your documentation or product pages improves SEO and guides developers straight to the provisioning flow.

9. Publishing the Post on UBOS Blog

UBOS uses a Markdown‑to‑HTML pipeline, but you can paste the HTML directly into the blog editor. Follow these steps to ensure the article is SEO‑friendly and AI‑ready:

1. Set the meta title to “Getting Started with the OpenClaw Rating API SDK”. Include the primary keyword.
2. Add a meta description (150‑160 characters) that mentions “OpenClaw Rating API”, “SDK installation”, and “developer best practices”.
3. Upload a featured image that illustrates a rating widget; use an alt attribute like “OpenClaw rating widget example”.
4. Insert the HTML content from this guide. Verify that all <h2> and <h3> tags are present for hierarchy.
5. Enable schema markup for Article using the built‑in UBOS SEO module.
6. Publish and share on LinkedIn, X, and relevant developer forums. Encourage comments by asking readers to share their integration challenges.

After publishing, monitor performance via the AI marketing agents dashboard, which can suggest keyword tweaks and internal linking opportunities.

10. Conclusion

The OpenClaw Rating API SDK empowers developers to embed sophisticated rating mechanics with minimal code, while UBOS handles the heavy lifting of security, scaling, and observability. By following the installation steps, configuring authentication correctly, and applying the best‑practice patterns outlined above, you’ll deliver a reliable feedback loop that drives product improvement and user engagement.
