What is APIVAI?
APIVAI is an AI developer tool that acts as an API gateway, giving you pay-as-you-go access to frontier Claude and GPT models through a single key with no subscription. It exposes both an OpenAI-compatible API and the Anthropic Messages format on the same key, so you can point existing tooling like Claude Code, Cursor, or the Anthropic SDK at it without rewriting integrations. Signup needs only email verification, with no credit card and no KYC, and the platform does not log request or response bodies, recording only usage metadata. Through one account you can switch across 12 Claude variants and 8 GPT models, which is useful when you want to drop a cheaper model into a workflow for routine calls and reserve a stronger one for hard tasks. The homepage states each key is limited to 60 requests per minute, and you scale throughput by provisioning additional keys. Payment is flexible: cards, crypto in USDT, Alipay, and WeChat Pay, with a minimum top-up of $10 (or ¥20 for Alipay/WeChat). APIVAI claims roughly 56 to 58 percent savings against Anthropic's list pricing and up to 86 percent below OpenAI, pricing a Claude Sonnet 4.6 message at about $0.0145 for a typical 4K-in, 1.5K-out call. For international developers who want metered access to both model families without committing to either vendor's billing, it is a practical option to compare on BestAIFor.
