FAQ
How much does Claude (Anthropic) cost?
Pricing starts at $0.3850 per million tokens for the most affordable variant. You pay per call from your credit balance — no monthly subscription, no minimum commitment. First $10 on signup are free.
Is this an official Anthropic API?

Can I use Claude (Anthropic) in production?
Yes. The endpoint is rate-limited to 20 requests per 10 seconds per API key, retries are idempotent via taskId, and async results are delivered via polling or webhook. Set a spend cap in dashboard settings to protect against runaway usage.
Which Claude (Anthropic) variant should I pick?
For first tests, start with the cheapest variant (lowest "Price USD" in the table above). Upgrade to higher-resolution or "Quality" tiers only when you have validated prompts. The Playground (free) lets you A/B test all variants before spending credits.
