Step 1: Set Up Claude API Key in Cursor
Here's how to configure your own Claude API Key in Cursor. This works for both Cursor Free and Cursor Pro users.
Open Cursor Settings
Press Cmd+, (Mac) or Ctrl+, (Windows) → Go to Models tab.
Add Custom API Endpoint
Click "Add Model" or "Override OpenAI Base URL". Set the Base URL to your API provider's endpoint.
Enter API Key
Paste your Claude API Key (starts with sk-) into the API Key field.
Select Claude Model
Choose claude-opus-4-20250115 for max intelligence, or claude-sonnet-4-20250514 for best speed/cost balance.
Example Configuration (for CheapClaude users)
Base URL: https://your-agent.cc/api
API Key: sk-xxxxxxxxxxxxxxxx (your key from CheapClaude)
Model: claude-opus-4-20250115That's it. Cursor will now use your own API Key — no Pro subscription required for Claude access.
Step 2: Get Claude API at 87% Off
Here's where most developers overpay. Anthropic's official Claude Opus 4.6 costs roughly $100 per 50M tokens. With CheapClaude, you get the exact same tokens for $13.
Save 87% — same model quality
How is this possible?
CheapClaude (powered by youragent) aggregates demand from 10,000+ developers and negotiates volume pricing. The token rate is official 1:1 — meaning 1 USD = 500,000 tokens, exactly the same as Anthropic. You're paying less per dollar of credit, but getting the same tokens.

Cursor Pro vs Own API Key: Which Saves More?
Many developers wonder: should I pay for Cursor Pro ($20/month) or bring my own API Key? Here's the real comparison:
| Cursor Pro ($20/mo) | Cursor Free + CheapClaude API | |
|---|---|---|
| Monthly cost | $20 fixed | Pay per use (from $13) |
| Premium requests | 500/month limit | Unlimited |
| Model choice | Cursor decides | You choose (Opus 4.6, etc.) |
| Throttling | After limit hit | Never |
| Agent Mode | ✓ | ✓ (with API Key) |
| Best for | Casual users | Heavy coders, teams |
Bottom line: If you send <100 requests/month, Cursor Pro is simpler. If you code heavily or want guaranteed Opus 4.6 access without throttling, your own API Key is both cheaper and better.
For Teams: Save Even More at Scale
If you're a small team (3-20 developers), using CheapClaude gets even better:
- Multi-Key management: Each team member gets their own API Key with independent usage tracking
- Team dashboard: Monitor everyone's token usage in real-time via New API panel
- Volume discounts: Teams spending $50+/month get 10% bonus credit on first top-up
- Bank transfer & invoicing: For accounting / expense reporting
- Unused balance refundable: Zero risk, zero lock-in

FAQ
Is cheap Claude API the same quality as official?
CheapClaude's Official Direct channel connects directly to Anthropic's API — 100% identical output. The Hybrid channel uses alternative routing but maintains the same model (no substitution). Always verify with your provider.
Can I switch between Cursor Pro and my own API Key?
Yes. Cursor allows you to use your own API Key regardless of subscription. Many developers use Cursor Free + their own Claude API Key to avoid the $20/month subscription entirely.
What if I'm not satisfied?
Unused balance is fully refundable. No subscription, no lock-in, no minimum purchase. You can stop anytime.
What other tools work with this API Key?
The same API Key works with: Claude Code, VS Code (Continue/Cline), JetBrains IDEs, OpenClaw, CC-Switch, opencode, SillyTavern, and any OpenAI-compatible client.
