The Problem: Cheap Models Still Have Expensive Risks
DeepSeek-V3 and R1 are known for cost-efficiency and strong reasoning. But if you call DeepSeek directly from the browser, your API key can leak through DevTools, build artifacts, or network logs.
Environment variables do NOT secure frontend builds. Serverless still requires secrets management, CORS configuration, and maintenance.
If your key leaks, your quota disappears.
What Happens When Your DeepSeek Key Leaks?
- Unauthorized usage draining your credits
- Abuse from scraped keys
- Unexpected billing spikes
- Service instability when limits are hit
The Solution: The Salting Layer
Instead of calling DeepSeek directly, you call your secure bridge:https://api.salting.io/r/salting-io-bridge-uuid
Your real DeepSeek API key stays encrypted inside Salting. We handle:
- Secret key vaulting
- AES-256 request encryption
- CORS enforcement
- IP & rate limiting
- Abuse protection
You get backend-level security without maintaining backend infrastructure.
How It Works
- Add your DeepSeek API key to your Salting dashboard.
- Generate a private Bridge URL.
- (Optional) Lock usage to your domain.
- Replace your client-side API calls with the bridge URL.
- Deploy instantly.
No proxy server. No Express boilerplate. No serverless setup.
Salting vs Traditional Backend Setup
🚧 Traditional Backend Proxy
- Requires Node.js / Go server
- Manual CORS configuration
- Secret key stored in your infrastructure
- Custom rate limiting implementation
- Ongoing maintenance + monitoring
☁ Serverless Function
- Cold starts possible
- CORS handling still required
- Secrets + deployment pipeline complexity
- Scaling cost spikes under load
⚡ Salting Layer (Recommended)
- No server required
- Encrypted API key vault
- Built-in CORS enforcement
- Integrated rate limiting
- Abuse protection by default
- Deploy in under 2 minutes
What Can You Build?
- High-volume AI chat systems
- Research agents
- Data extraction tools
- Internal copilots
- Cost-optimized SaaS AI features
Perfect for React, Next.js, Vue, Angular, static sites, and serverless apps.
Frequently Asked Questions
Does Salting support DeepSeek models like V3 and R1?
Yes. Salting forwards requests transparently to supported DeepSeek models.
Is Salting a proxy?
Technically yes — but optimized for security, speed, and zero infrastructure management.
Does this replace my backend?
If your backend exists mainly to hide keys and manage usage, yes.
Can I apply rate limits per bridge?
Yes. Each bridge URL supports custom rate limits.
Does Salting add latency?
Minimal edge overhead (typically sub-30ms).
Stop Exposing Your DeepSeek Key
If your frontend can see your DeepSeek key, attackers can too. Secure it in minutes and scale safely.
