Instead of integrating each AI provider separately, you connect once to Eden AI and get instant access to the entire AI ecosystem. ```mermaid theme={null} flowchart LR App["Your App"] Gateway["Eden AI Gateway"] OpenAI["OpenAI"] Anthropic["Anthropic"] Google["Google"] AWS["Amazon"] More["50+ providers..."] App -->|Single API Key| Gateway Gateway --> OpenAI Gateway --> Anthropic Gateway --> Google Gateway --> AWS Gateway --> More ``` ## Two Endpoints, Full Coverage Eden AI V3 organizes all AI capabilities under two main endpoints: | Endpoint | Purpose | Model Format | | --------------------------- | ------------------------------------------------------------- | ------------------------------------- | | `POST /v3/chat/completions` | LLMs (chat, text generation, vision, tool calling) | `provider/model` | | `POST /v3/universal-ai` | Expert models (OCR, text analysis, image, translation, audio) | `feature/subfeature/provider[/model]` | Both endpoints share the same base URL and authentication. ## Base URL ``` https://api.edenai.run/v3 ``` ## Authentication All requests require a Bearer token in the `Authorization` header: ``` Authorization: Bearer YOUR_API_KEY ``` Get your API key from the [Eden AI dashboard](https://app.edenai.run/). ## Key Benefits Connect once to Eden AI and access every supported AI provider. No need to manage separate SDKs or API keys for each provider. One invoice for all your AI usage. Every API response includes a `cost` field in USD so you always know exactly what you spent. The LLM endpoint follows the OpenAI chat completions format. Use any OpenAI-compatible SDK or tool and just change the base URL. Switch between providers by changing a single string in your request. No code changes needed. Upload files once and reference them by UUID across multiple requests and features. Explore available models, features, and input schemas programmatically through the listing endpoints. ## Pay-Per-Use Pricing Eden AI uses a **pay-per-use** model. You only pay for the API calls you make. Every response includes a `cost` field showing the exact charge in USD: ```json theme={null} { "status": "success", "cost": 0.0015, "output": { ... } } ``` No minimum commitments, no upfront fees. See [Plans & Pricing](/v3/overview/plans-prices) for details on available tiers. ## Quick Example ```python Python theme={null} import requests # LLM call response = requests.post( "https://api.edenai.run/v3/chat/completions", headers={ "Authorization": "Bearer YOUR_API_KEY", "Content-Type": "application/json" }, json={ "model": "openai/gpt-4", "messages": [{"role": "user", "content": "Hello!"}] } ) print(response.json()["choices"][0]["message"]["content"]) ``` ```bash cURL theme={null} curl -X POST https://api.edenai.run/v3/chat/completions \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "openai/gpt-4", "messages": [{"role": "user", "content": "Hello!"}] }' ``` ```javascript JavaScript theme={null} const response = await fetch('https://api.edenai.run/v3/chat/completions', { method: 'POST', headers: { 'Authorization': 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json' }, body: JSON.stringify({ model: 'openai/gpt-4', messages: [{role: 'user', content: 'Hello!'}] }) }); const result = await response.json(); console.log(result.choices[0].message.content); ``` If you were a user before January 2026, you still have access to the previous version at [old-app.edenai.run](https://old-app.edenai.run/). The old version will continue to be supported until the end of 2026. Documentation for the previous version is available at [old-docs.edenai.co](https://old-docs.edenai.co). ## Next Steps Send a chat completion request in under a minute. Try OCR, text analysis, or image generation with a single endpoint.
