Claude API Gateway — Unified Access to All Claude Models
ClaudeStore API gateway provides unified access to all Claude models via Anthropic-compatible and OpenAI-compatible endpoints. One API key, multiple formats.
TL;DR
ClaudeStore acts as an API gateway for Claude models — providing both Anthropic-native and OpenAI-compatible endpoints through a single API key. No waitlist, instant access, same models and pricing.
What Is a Claude API Gateway?
A Claude API gateway is a proxy service that routes your requests to Anthropic's Claude models while adding convenience features: dual-format endpoints (Anthropic + OpenAI), instant signup, credit-based billing, and crypto payments.
Instead of managing separate API keys for different tools, you get one key that works everywhere — Cursor, VS Code, Claude Code, Python SDK, OpenAI SDK, and plain HTTP.
Two Endpoints, One Key
| Endpoint | Base URL | Format | Best For |
|---|---|---|---|
| Anthropic Messages | https://api2.claudestore.store/v1/messages | Anthropic SDK | Python/TS Anthropic SDK, Claude Code |
| OpenAI Compatible | https://api2.claudestore.store/v1 | OpenAI SDK | Cursor, VS Code, any OpenAI-compatible tool |
Quick Examples
Anthropic Format
