Claude API — Perguntas Frequentes

Which Claude models are available?

Currently available: claude-sonnet-4-6, claude-opus-4-7, claude-opus-4-8 — the same models Anthropic offers, all reachable through one key.

Which Claude model should I choose?

Pick Haiku for fast, low-cost tasks; Sonnet for the best balance of speed and quality; Opus for the most complex reasoning and analysis.

How is it billed? Is there a minimum?

Billed per token (input + output) — see the price table above. Pay-as-you-go with Alipay, WeChat Pay, USDT and credit card, from as little as $1.

Is it compatible with the Anthropic SDK and Claude Code?

Yes. We expose both an OpenAI-compatible endpoint and an Anthropic-style one: Cursor, Codex and any OpenAI SDK just need the base URL changed; for Claude Code, set ANTHROPIC_BASE_URL and your key.

Is my data safe?

Yes. Your API data is not stored or used for training, and all requests are sent over encrypted connections.

Why is it cheaper than buying from Anthropic directly?

We aggregate volume across channels and bill strictly per token with no minimums, so the effective price lands well below Anthropic's official list price.
