Overview

ApiPass is a unified API platform that gives developers access to over 180 leading AI models from providers like OpenAI, Google, Anthropic, and more through a single API key and billing system. It supports text, image, video, and audio generation with a consistent request schema, async job pipeline, and webhook callbacks. ApiPass is designed for developers and teams who want to reduce API costs and simplify integration across multiple model providers.

How it works

ApiPass provides a single API key that works across all models in its marketplace, including Claude, GPT, Gemini, Veo, Kling, Flux, Suno, and more. Developers can submit a generation task with a single POST request using a predictable request schema, then poll the task status by taskId or receive results via webhook callbacks. The platform supports async job pipelines for long-running image, video, and music tasks, ensuring applications remain responsive.

Key capabilities

ApiPass offers drop-in compatibility with official APIs, allowing developers to swap the baseURL and API key without rewriting code. It includes officially maintained SDKs, a browser playground for testing models without code, and open-source toolkits like workflow-canvas and apipass-workflow-nextjs. The platform also provides real-time 24-hour success-rate monitoring, enterprise-grade security with end-to-end encryption, and 24/7 human support.

Who it is for

ApiPass is built for developers and teams building AI-powered applications who want to reduce API costs and simplify integration across multiple model providers. It is suitable for production workloads with high-availability infrastructure, task status queries, request logs, and enterprise support options. The platform also offers an affiliate program where users can earn 15% commission on referred customers' first-month purchases.

Pricing and limits

ApiPass uses a pay-as-you-go credit system with no subscription lock-in. Pricing is based on credits, with a rate of $0.005 per credit, and users pay only for successful calls. New users receive 50 free credits on signup to test models in the browser. The platform claims pricing is 30%-70% lower than official pricing, with specific examples like GPT Image 2.5 at $0.001 per image compared to $0.178 official.
