Use Cline with a cheaper API after Anthropic's subscription change

On April 4, 2026, Anthropic stopped letting Claude subscriptions power third-party tools — Cline, Cursor, Windsurf and others. If your Cline setup suddenly stopped working, that’s why. The fix is to connect Cline to a pay-as-you-go API instead of a subscription.

A unified gateway like nexinfer lets you keep using Claude (and switch to GPT, Gemini or DeepSeek for cheaper tasks) through one OpenAI-compatible endpoint — billed by usage, with published rate limits so your agent runs don’t hit a hidden 429.

Why a gateway instead of one provider’s key

The cheapest setup for agentic coding is rarely a single model — it’s routing: keep a strong model for hard refactors, drop simple edits to a cheaper one. A gateway gives you every model behind one key and one bill.

Setup in Cline

1. Open Cline’s settings → API Provider.
2. Choose an OpenAI-Compatible provider.
3. Fill in:

Base URL:  https://api.nexinfer.com/v1
API Key:   sk-nexinfer-xxxx
Model:     claude-opus-4   (or gpt-5, gemini-2.5-pro, deepseek-v3 …)

4. Save and start coding.

That’s it — Cline now runs on pay-as-you-go pricing with no subscription lock.

Avoid the common traps

After the April change, a lot of cheap relays appeared. Before you trust one with your prompts and key:

• Real models, not swapped — verify you get the model you selected.
• Published RPM & concurrency — so long agent runs don’t get throttled to a crawl.
• No request logging — your code isn’t harvested.
• Transparent billing — multipliers and cache rates you can audit.

Frequently asked questions

Why did my Claude subscription stop working in Cline? Anthropic’s April 2026 policy ended third-party harness access on subscription plans. API billing still works — that’s what a gateway provides.

Can I still use Claude in Cline? Yes — through API access via the gateway, plus GPT, Gemini, DeepSeek and more from the same key.

Will I hit rate limits mid-task? With nexinfer the per-key RPM is published, so you can size your runs — no silent throttling. Check current limits on the homepage.
