About ai-api.cloud

ai-api.cloud is a unified API gateway to frontier LLMs. One key and one balance give you access to multiple models through both OpenAI-compatible (/v1/chat/completions) and native Anthropic (/v1/messages) endpoints, with transparent per-token billing and cache-aware pricing.

What you get

• A single API key that works across models and both protocols.
• Transparent billing in USD — every request records the model, tokens, cache and the exact charge.
• A self-service cabinet: keys, usage, balance and setup guides.

Contact

• Support: support@ai-api.cloud — account, keys, billing and technical help. Signed-in users can also open a support ticket in the cabinet.
• Partnerships & proposals: manager@ai-api.cloud — business, cooperation and custom plans.

We aim to reply within one business day.
