How much does Claude API cost?

Claude API pricing is per-token. Anthropic's current public rates are $1/$5 per 1M tokens for Haiku 4.5, $3/$15 for Sonnet 4.6, and $5/$25 for the Opus tier. ClaudeStore sells discounted Anthropic-equivalent usage packs: $45 buys $500 of usage and $90 buys $1,000. Opus 4.8 is available through the same API3 balance.

Claude API is not free — it uses pay-per-token pricing. ClaudeStore sells one-time Anthropic-equivalent usage packs starting at $45, with no recurring charge.

Which models are available?

ClaudeStore gives one-key access to the current Opus, Sonnet, and Haiku families, including Claude Opus 4.7, Claude Opus 4.8, Claude Sonnet 4.6, and Claude Haiku 4.5.

Which Claude model is best for coding?

Claude Sonnet 4.6 is the default choice for daily coding and agent workflows. Use Opus 4.7 or Opus 4.8 for complex refactors, architecture, long sessions, and high-stakes reasoning; use Haiku 4.5 for fast low-cost tasks.

What base URL should I use?

Use https://api3.claudestore.store as your base URL. For the Anthropic-compatible API, the messages endpoint is POST /v1/messages. For OpenAI-compatible, it's POST /v1/chat/completions.

What's the difference between Anthropic and OpenAI-compatible modes?

Anthropic mode uses x-api-key header and anthropic-version header with the Messages API format. OpenAI mode uses Authorization: Bearer header with the Chat Completions format. Both access the same Claude models.

How do I get a ClaudeStore API key?

Sign up, add a one-time usage pack, and generate an API key from the dashboard. Available model IDs can be checked through GET /v1/models.

What are the rate limits?

ClaudeStore uses protective per-key and global gateway limits rather than a fixed public RPM table. If you hit 429, respect Retry-After, reduce concurrency, and contact support for sustained higher throughput.
