AI Gateway

AI Gateway provides a unified endpoint for accessing multiple LLM providers (Azure OpenAI, Google Vertex AI Gemini, Anthropic via Vertex AI) through a single OpenAI-compatible API, with platform-managed credentials and workspace-scoped authentication.

Overview

AI Gateway provides:

• A unified, OpenAI-compatible endpoint for multiple LLM providers
• Mandatory authentication via your workspace's auth (request tokens are resolved against the configured auth namespace)
• Per-workspace isolation: each gateway is provisioned with its own platform-assigned URL
• Optional CORS allow-list for browser-based clients
• Built-in usage tracking and rate limiting (configured platform-side)

Configuration

Configure an AI Gateway using defineAIGateway():

Definition Rules:

• Multiple gateways allowed: You can define multiple AI Gateways in your config file
• Configuration location: Define in tailor.config.ts and add to the aiGateways array
• Uniqueness: Gateway names must be unique across all AI Gateways
• Name pattern: name must match ^[a-z0-9][a-z0-9-]{1,28}[a-z0-9]$ (lowercase alphanumeric and hyphens, 3-30 characters)

import { defineAIGateway, defineConfig } from "@tailor-platform/sdk";

const aiGateway = defineAIGateway("my-aigateway", {
  authNamespace: "default",
});

export default defineConfig({
  aiGateways: [aiGateway],
});

Options

authNamespace

The auth namespace used to resolve request tokens against your workspace's auth configuration. Must match an existing auth namespace.

defineAIGateway("my-aigateway", {
  authNamespace: "default",
});

cors

Optional list of allowed origins for browser-based clients. Each entry is one of:

• * — any origin (any scheme, any host)
• http(s)://* — any host on the given scheme
• http(s)://*.example.com — any subdomain of example.com on the given scheme
• http(s)://app.example.com — an exact origin

An optional :port may be appended in all URL forms. Omitting cors (or passing []) disables cross-origin access — browsers will block any cross-origin reads.

defineAIGateway("my-aigateway", {
  authNamespace: "default",
  cors: ["https://app.example.com", "https://*.example.com"],
});

Complete Example

import {
  defineAIGateway,
  defineAuth,
  defineConfig,
  defineStaticWebSite,
} from "@tailor-platform/sdk";

const website = defineStaticWebSite("my-frontend", {
  description: "Frontend application",
});

const aiGateway = defineAIGateway("my-aigateway", {
  authNamespace: "default",
  cors: [website.url],
});

const auth = defineAuth("my-auth", {
  // ...auth configuration...
});

export default defineConfig({
  name: "my-app",
  auth,
  staticWebsites: [website],
  aiGateways: [aiGateway],
});
