Why use us
- Official access, verifiable source
Requests reach each model’s official API, and a third-party signed receipt lets you verify which model answered.
- Usage-based billing
You’re billed for the usage the provider reports, and 8 models cost less than official prices. Every request has an itemized receipt.
- Multi-provider failover
If a provider becomes unavailable, requests fail over to another; provider uptime is published.
- One key, native protocols
Native OpenAI, Anthropic and Gemini APIs; Claude Code and Codex connect by changing the base URL.
