Announcing APISIX Integration with AI/ML API

#ai #api #apigateway #tutorial

We're thrilled to announce that AI/ML API has become a supported provider to the ai-proxy, ai-proxy-multi, and ai-request-rewrite plugins in Apache APISIX. All the AI/ML APIs will be supported in the next APISIX version.

Introduction

AI/ML API is a single endpoint that gives you access to more than 300 ready-to-use AI models—large language models, embeddings, image and audio tools—through one standard REST interface. It is used by over 150,000 developers and organizations as a centralized LLM API gateway.

We're thrilled to announce that AI/ML API has become a supported provider to the ai-proxy, ai-proxy-multi, and ai-request-rewrite plugins in Apache APISIX.

AI/ML API provides a unified OpenAI-compatible API with access to 300+ LLMs such as GPT-4, Claude, Gemini, DeepSeek, and others. This integration bridges the gap between your API infrastructure and leading AI services, enabling you to deploy intelligent features—like chatbots, real-time translations, and data analysis—faster than ever.

Proxy to OpenAI via AI/ML API

Prerequisites

  1. Install APISIX.
  2. Generate your API key on AI/ML API dashboard. Generate AI/ML API Key

Configure the Route

Create a route and configure the ai-proxy plugin as such:

curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
  -H "X-API-KEY: ${ADMIN_API_KEY}" \
  -d '{
    "id": "ai-proxy-route",
    "uri": "/anything",
    "methods": ["POST"],
    "plugins": {
      "ai-proxy": {
        "provider": "aimlapi",
        "auth": {
          "header": {
            "Authorization": "Bearer '"$OPENAI_API_KEY"'" # Generated openai key from AI/ML API dashboard
          }
        },
        "options":{
          "model": "gpt-4"
        }
      }
    }
  }'
Enter fullscreen mode Exit fullscreen mode

Test the Integration

Send a POST request to the route with a system prompt and a sample user question in the request body:

curl "http://127.0.0.1:9080/anything" -X POST \
  -H "Content-Type: application/json" \
  -H "Host: api.openai.com" \
  -d '{
    "messages": [
      { "role": "system", "content": "You are a mathematician" },
      { "role": "user", "content": "What is 1+1?" }
    ]
  }'
Enter fullscreen mode Exit fullscreen mode

Verify Response

You should receive a response similar to the following:

{
  ...,
  "choices": [
    {
      "index": 0,
      "finish_reason": "stop",
      "logprobs": null,
      "message": {
        "role": "assistant",
        "content": "1 + 1 equals 2.",
        "refusal": null,
        "annotations": []
      }
    }
  ],
  "created": 1753845968,
  "model": "gpt-4-0613",
  "usage": {
    "prompt_tokens": 1449,
    "completion_tokens": 1008,
    "total_tokens": 2457
  ...
}
Enter fullscreen mode Exit fullscreen mode

Core Use Cases

1.Unified AI Service Management

  • Multi-Model Proxy and Load Balancing: Replace hardcoded vendor endpoints with a single APISIX interface, dynamically routing requests to models from OpenAI, Claude, DeepSeek, Gemini, Mistral, etc., based on cost, latency, or performance needs.
  • Vendor-Agnostic Workflows: Seamlessly switch between models (e.g., GPT-4 for creative tasks, Claude for document analysis) without code changes.

2.Cost-Optimized Token Governance

  • Token-Based Budget Enforcement: Set per-team/monthly spending limits; auto-throttle requests when thresholds are exceeded.
  • Caching & Fallbacks: Cache frequent LLM responses (e.g., FAQ answers) or reroute to cheaper models during provider outages.

3.Real-Time AI Application Scaling

  • Chatbots & Virtual Agents: Power low-latency conversational interfaces with streaming support for token-by-token responses.
  • Data Enrichment Pipelines: Augment APIs with AI—e.g., auto-summarize user reviews or translate product descriptions on-the-fly.

4.Hybrid/Multi-Cloud AI Deployment

  • Unified Control Plane: Manage on-prem LLMs (e.g., Llama 3) alongside cloud APIs (OpenAI, Azure) with consistent policy enforcement.
  • High Availability & Fault Tolerance: Built-in health-checks, automatic retries and failover; if one LLM fails, traffic is rerouted within seconds to keep services alive.

5.Enterprise AI Security & Compliance

  • Data Security and Compliance: Prompt Guard, content moderation, PII redaction, and full audit logs in a single place.
  • One Auth Layer for 300+ LLMs: Unified authentication (JWT/OAuth2/OIDC) and authorization for 300+ LLM keys and policies.

Conclusion

With AI/ML API now natively supported in Apache APISIX, you no longer have to choose between speed, security, or scale—you get all three.

  • One line of YAML turns your gateway into a 300-model AI powerhouse.
  • Zero code changes let you hot-swap GPT-4 for Claude, or route 10 % of traffic to a cheaper model for instant cost savings.
  • Built-in guardrails (PII redaction, token budgets, content moderation) keep compliance teams happy while your product team ships faster.
