Lunar

Lunar is an enterprise-grade API management and AI control plane platform that provides a unified gateway for managing API traffic policies, rate limiting, quota enforcement, and API monetization across gateways. The platform combines an API consumption gateway with an MCP (Model Context Protocol) gateway to govern, secure, and observe interactions between AI agents, APIs, and data sources. Lunar delivers real-time visibility into model, API, and tool invocations alongside policy-based enforcement, cost controls, and advanced traffic shaping including retries, priority queues, and circuit breakers.

Lunar publishes 6 APIs on the APIs.io network, including Configuration API, Discovery API, Doctor API, and 3 more. Tagged areas include API Management, API Gateway, AI Gateway, MCP Gateway, and Rate Limiting.

The Lunar catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Lunar’s developer surface includes documentation, engineering blog, pricing, signup flow, YouTube channel, product news, and 11 more developer resources.

  name: Lunar API Consumption Gateway
  description: The Lunar API Consumption Gateway is a proxy-based infrastructure layer that routes outbound HTTP/HTTPS API
    traffic through configurable YAML-based flows. It enforces rate limits, quota policies, priority queues, circuit breakers,
    and endpoint access controls without requiring code changes in consuming applications. Requests are routed by setting
    x-lunar-scheme, x-lunar-host, and x-lunar-consumer-tag headers and targeting the gateway on port 8000.

  name: Lunar MCPX Gateway
  description: The Lunar MCPX Gateway is an agent-native Model Context Protocol gateway that governs tool invocation for AI
    agents. It consolidates multiple MCP servers into a single endpoint, providing authentication, scoped permissions, secret
    forwarding, audit trails, and risk evaluation for AI agent workloads. The MCPX gateway supports role-based access control,
    tool groups, tool customization, and remote MCP authentication.
