Why one key

Many models. One API key.

Switch models without switching accounts, keys or billing.

Every model behind the same key

Pick the model per task: a strong model for hard refactors, a cheaper one for quick edits.

FAQ

Questions, answered

How do I get the free trial?

Tap any WhatsApp button on this page and send the pre-filled message. We reply with a trial key, the Base URL and setup steps for your tool.

Which tools does it work with?

Anything that accepts a custom Base URL and API key: Claude Code, Cursor, Cline, Codex, OpenCode, and most OpenAI-compatible clients and SDKs.

How does billing work?

Pay as you go. You top up a balance, and each call is charged by the tokens it uses at that model's price. Your usage log lists requests, tokens and cost per call.

How do I pay?

Payment options depend on your country. Message us on WhatsApp and we'll send the ones available to you.

What happens when the trial credits run out?

Calls stop until you top up. Nothing is charged automatically.

Are you affiliated with Anthropic, OpenAI or Google?

No. WTCity API is an independent API service. Model and product names belong to their respective owners.
