How to Cut Data Costs Using DPSN’s Pay‑Per‑Event Model
Why This Matters: Stop Paying for Data You Don’t Use
If you’ve ever signed up for a data subscription and barely scratched the surface of what you paid for, you’re not alone. Most platforms push flat fees or fixed tiers that sound simple, but don’t scale with your usage.
That’s where DPSN stands out.
Instead of paying a fixed amount every month, you only pay for the exact data events you consume. That’s it. No fluff, no overage charges, and no guessing games.
What is DPSN, Really?
Think of DPSN (Decentralized Pub/Sub Network) as a live data marketplace built for developers. It connects publishers (people pushing real-time data) with subscribers (like you and me) who need that data for apps, bots, dashboards, and more.
You can browse available streams called topics and subscribe using the CLI, SDK, or REST API. The best part? You’re charged per event received. Not per hour. Not per day. Just per event.
How the Pricing Actually Works
Let’s break it down:
Every topic in the DPSN Marketplace clearly lists its price per 1,000 events.
When you subscribe, you’re billed only when data is delivered.
Everything is tracked in real time on your dashboard, no guesswork.
There’s no monthly minimum. No “basic plan.” If you don’t consume anything, you don’t pay anything.
And you’re never locked in. Want to unsubscribe for a few hours or days? Go ahead. You’re in control.

Real-World Example: Pay Only for What You Use
Say you’re running a crypto dashboard and need three live feeds:
ETH Gas Prices
BTC Price
Ethereum Mempool Activity
You subscribe to three topics, and over 24 hours, you receive about 9,500 events.
Credits are charged based on actual usage, depending on how many events you consume.
That’s it. No subscription fees. No idle charges. Just a direct, clean link between usage and cost.
How to Keep Costs Low (Without Sacrificing Performance)
Here are a few ways to squeeze the most value out of DPSN:
1. Be selective with topics
Not all streams are worth subscribing to. Start with what you truly need and expand once your system is live.
2. Use filtering logic
The DPSN SDK makes it easy to ignore noise. For example, don’t process minor price changes or duplicate events.
3. Set usage alerts
You can track how many events you’ve consumed and monitor credits in real-time. Top up only when needed.
4. Automate unsubscribes
If your service runs only during market hours or business days, pause streams after-hours to save on data.
Built for Developers
This isn’t a platform you’ll struggle to integrate. DPSN was built with developers in mind.
Use the CLI for quick setup and local testing.
Integrate the SDK directly into your Node.js backend.
Or tap into the REST API if you prefer a more classic setup.
And the dashboard? It’s straightforward. You see what you’re consuming, how much you’re spending, and what’s happening live.

Frequently Asked Questions (FAQs)
Q: Do I have to pay to subscribe to a topic? Nope. You only pay for events you receive. If nothing comes in, you’re not charged.
Q: What if I run out of credits mid-stream? Your data delivery pauses until you top up. The dashboard shows credit balance in real time, so it’s easy to stay ahead.
Q: Can I cancel or pause a subscription? Absolutely. You can unsubscribe at any time from the CLI, SDK, or dashboard.
Q: How do I know what each stream costs? Each topic in the Marketplace displays pricing per 1,000 events clearly. No hidden fees.
Q: Is this secure? Yes. DPSN uses encryption and blockchain-backed authentication to protect data integrity and access.
Final Thoughts
DPSN’s pay‑per‑event pricing just makes sense. Whether you're running an AI agent, a trading bot, or just need reliable real-time data, this model lets you start small and scale up—without the financial friction.
You don’t need a giant budget or a team of DevOps engineers. You need flexibility, cost control, and data that fits your workflow. That’s exactly what DPSN delivers.
