Unified multi-provider gateway
Access models from providers including OpenAI, Anthropic, Google, DeepSeek, MiniMax, Zhipu, and xAI through one platform and API key.
4ALL API
Freemium
4ALL API is an API aggregation gateway for enterprises and developers that provides one access layer for text, image, video, and audio models from multiple providers. It supports OpenAI-compatible access, usage-based billing, model routing, and failover workflows.
4ALL APIとは？
4ALL API is an enterprise and developer-oriented gateway for accessing multiple AI model providers through one platform and API key. Its catalog includes text, image, video, and audio capabilities, with examples spanning GPT, Claude, Gemini, DeepSeek, MiniMax, GLM, and other provider models. The service is intended to reduce the need to integrate and operate separate provider endpoints for each model family.
The gateway exposes an OpenAI-compatible workflow. Existing OpenAI SDK projects can generally connect by changing the base URL to https://api.4allapi.com/v1 and replacing the API key, while continuing to use the existing SDK or an HTTP client. The documented chat endpoint is /v1/chat/completions; the site also identifies image, video, and audio endpoint families for corresponding capabilities.
Pricing is usage-based rather than subscription-plan based. The pricing page presents model costs by token, request, or second, depending on the model or capability, and provides a model catalog for comparing text, image, video, and audio options. Users should consult the current catalog and documentation before choosing a production route.
4ALL APIでできること
OpenAI-compatible migration
Connect an existing OpenAI SDK or HTTP client by changing the base URL and API key; the documented base URL is https://api.4allapi.com/v1.
Multimodal model access
The catalog covers text chat, image generation, video generation, and audio processing, with separate endpoint families described for these capabilities.
Routing and failover controls
Partition routes by task type and configure primary and fallback choices using latency, cost, and success-rate considerations.
Usage observability and cost controls
Logs and metrics support model-level monitoring of usage, quota consumption, latency, error rates, retry costs, and project spending.
利用シーン
“Batch content production”
Generate short-video scripts, cover images, advertising assets, and social content by combining text, image, and video models in a repeatable workflow.
“E-commerce visual marketing”
Produce product scene images, model try-ons, and marketing posters to support merchandising and campaign production.
“Automated customer service”
Assign questions to models according to complexity, balancing response quality with model cost and route stability.
“Code-assisted development”
Give development teams a single access layer for code-capable models such as Claude, GPT, and DeepSeek, with model selection suited to different technical stacks.
“Research and education workflows”
Use long-context models for structured financial research summaries, or select models dynamically for student questions ranging from basic explanations to competition coaching.
よくある質問
How do I connect an existing OpenAI SDK project?
Change the SDK base_url to https://api.4allapi.com/v1 and replace the API key. The site states that most SDK calls do not need to be rewritten.
Which request endpoint is documented for chat?
The documented chat endpoint is POST https://api.4allapi.com/v1/chat/completions, using Bearer-token authentication.
How does routing handle provider or model instability?
4ALL API describes multi-provider routing, health checks, and automatic failover. Routes can be organized by task type with primary and fallback choices based on latency, cost, and success rate.
How is usage billed?
Model pricing is usage-based and may be calculated by token, request, or second, depending on the model or capability. Current rates are listed in the pricing and model catalog pages.
What should I do if a request receives a 429 rate-limit error?
The site recommends exponential backoff with jitter, reducing concurrency, and switching to an available model group when necessary.
