We built Vexrail to solve a straightforward problem: advertisers want to reach users inside AI conversations, and publishers running AI applications want a way to monetize them. Vexrail connects both sides through a single, OpenAI-compatible API.

What You Can Do Today​

Advertisers​

Create campaigns to promote your products inside AI conversations across our publisher network. You set a CPC bid and budget, assign your products, and go live. You pay only when users click.

• Create projects and verify your domain.
• Add products with descriptions that drive contextual matching.
• Launch campaigns with daily or total budgets.
• Track performance with real-time analytics.

Publishers​

Monetize your AI application by integrating the Vexrail API. If you already use the OpenAI SDK, LangChain, Vercel AI SDK, or any OpenAI-compatible client, integration takes minutes -- change the base URL, add your API keys, and enable monetization.

• Drop-in integration with any OpenAI-compatible SDK.
• Earn revenue from contextual ad clicks in your AI responses.
• Track conversations, token usage, and earnings.
• Withdraw earnings to your bank account.

The API​

The Vexrail API follows the OpenAI chat completions format. Point any compatible SDK at https://api.vexrail.com/v1, authenticate with your API keys, and start making requests. Streaming and non-streaming responses are both supported.
