FAQ

Common questions

Short answers to the questions that usually matter before buying an API key.

How much does the Claude API cost?+
Enter any positive whole USD top-up amount. Each request is converted to official API spend, then your active discount is applied: B2C progresses from 60% to 80% off, while B2B pricing is negotiated.
Is there a free option?+
Yes — every new B2C account gets $10 of Claude usage at official API prices, enough to wire up your tools and run real calls.
Which models are available?+
The full current Claude line — Opus 4.8, Opus 4.7, Sonnet 4.6, Haiku and more — all on the same balance and the same key.
Which Claude model is best for coding?+
For agentic coding and long sessions, Opus and Sonnet tiers give the best results; Haiku is ideal for fast, cheap calls.
What base URL should I use?+
Point any Anthropic-compatible tool at the platform gateway, or use the /v1 path for OpenAI-compatible clients. Both share one key and balance.
What are the rate limits?+
Per-key request caps are configurable in the dashboard, so you can protect your balance and split limits across tools.
