About Zuplo

Zuplo is a commercial API gateway that teams program through code and configuration. It handles authentication, rate limiting and audit for APIs, and includes API key management and a developer portal so API owners can onboard consumers without building that tooling themselves.

The vendor now describes Zuplo as a unified gateway for APIs, AI and MCP. One policy engine applies authentication, rate limits, spend caps and audit to outbound calls from an application to language models, and to inbound calls from AI agents to an API. Consumers can use API keys, JWT and OAuth with per-key rate limits, and agents get scoped, audited access through MCP. The site mentions a security attestation, and offers case studies and a demo. Zuplo is proprietary and vendor-hosted, with a free start, documentation and a pricing page.
