FAQ

Is this really a free Claude API key?

Yes — sign up gives you an sk-cc-... key with no credit card. The Basic plan is free forever at 70% off official prices. You only pay (in crypto) for actual API usage above the included credit. Many users never pay if their use is light.

How is this different from Anthropic's free tier?

Anthropic doesn't have a permanent free API tier — you get evaluation credit that runs out. ClaudeAPI.cheap's Basic plan is permanent: 70% off forever, with crypto top-up when you need more usage. Same Claude models, same SDKs.

Can I use this key with Claude Code?

Yes. Set ANTHROPIC_BASE_URL=https://claudeapi.cheap/api/proxy and ANTHROPIC_AUTH_TOKEN=sk-cc-... and Claude Code works unchanged. Same trick works for Cline, Aider, OpenClaw, Cursor, OpenCode.

Is this a scam? It sounds too cheap.

It's a paid reseller, not a scam. We buy upstream API credit in bulk and resell at 70-80% off — crypto-only payment removes Stripe fees + chargeback risk, which is what makes the deeper discount work. Same Claude models, exact same API contract, no modifications.

What happens to my key if I run out of free credit?

Top up with USDT, BTC, ETH, or 100+ other coins via Oxapay. Credits never expire. Your key keeps working at 70% off. Or upgrade to Pro ($19 lifetime, one-time) for 80% off forever.
