1,000,000

Token Context Window

Primary Model: Claude 3.5 Sonnet✓ Sub-50ms Latency

Infrastructure Control & Isolation

Multi-tenant key management built to support teams and developers with 5-hour rolling windows.

Per-Key 5-Hour Rolling Budgets

Every key carries its allowance on a rolling five-hour window. Watch it drain in real time; it resets automatically on cycle.

Isolated Rate Limits (RPM)

Requests per minute and expiration dates are set per key. No single high-volume key can starve another developer.

Pass-Through SSE Streaming

Server-sent events are streamed token-by-token with sub-50ms latency directly to your IDE or application.

Zero-Cost Prompt Caching

Cache hits and prompt cache reads do not count against your 5-hour rolling window. Only fresh completions deduct.

Drop-In Protocol Compatibility

Full Anthropic Messages (/v1/messages) and OpenAI ChatCompletions (/v1/chat/completions) drop-in endpoints.

Multi-Surface Stack Support

Use one key across Claude Code CLI, Cursor, Windsurf, Continue, VS Code, Python SDK, TypeScript SDK, and cURL.

Automated Developer Onboarding

From API key to ready in seconds.

Eliminate manual configuration files. The official LightningDeals CLI configures all your favorite AI developer tools in one step.

Frequently Asked Questions

Everything you need to know.

Answers to common questions regarding 5-hour rolling token windows, WhatsApp key setup, CLI setup, API routing, and security controls.

Every key is assigned a 5-hour rolling token window. As you send API calls, token usage drains your window allowance. The window automatically resets on cycle, giving you fresh token capacity continuously.
