As answered by people managing Postman for Mac (Beta) and MandAPI.
MandAPI's answer:
MandAPI is primarily built for software developers, indie hackers, AI startups, SaaS teams, agencies and technical teams that need programmatic access to multiple large language models through a unified API.
MandAPI's answer:
MandAPI combines multiple AI model families behind a single OpenAI-compatible API. Developers can access GPT, Claude, Gemini, DeepSeek and other models without maintaining separate integrations for every provider. It also provides transparent usage-based pricing, model discovery, usage tracking and developer tooling.
MandAPI's answer:
MandAPI is designed for developers who want a simple way to use multiple AI providers through one familiar API. Its OpenAI-compatible interface makes migration straightforward, while unified billing, model discovery, transparent pricing and support for multiple model families reduce the operational work required to manage several AI APIs separately.
MandAPI's answer:
MandAPI started from a simple problem: developers increasingly need access to several AI model providers, but every provider has different APIs, pricing systems and account requirements. MandAPI was built to simplify that fragmented experience by providing a single OpenAI-compatible interface for multiple model families, with transparent pricing and developer-focused tooling.
MandAPI's answer:
MandAPI is built around an OpenAI-compatible REST API architecture with streaming support, API-key authentication, multi-provider routing, usage metering and model catalog services. The production platform uses containerized cloud infrastructure, reverse proxying and CDN services for deployment and traffic delivery.
