Configuration & Setup

Creating a Gateway

Dashboard

AI > AI Gateway > Create Gateway > Configure (auth, caching, rate limiting, logging)

API

curl -X POST https://api.cloudflare.com/client/v4/accounts/{account_id}/ai-gateway/gateways \
  -H "Authorization: Bearer $CF_API_TOKEN" -H "Content-Type: application/json" \
  -d '{"id":"my-gateway","cache_ttl":3600,"rate_limiting_interval":60,"rate_limiting_limit":100,"collect_logs":true}'

Naming: lowercase alphanumeric + hyphens (e.g., prod-api, dev-chat)

Wrangler Integration

[ai]
binding = "AI"

[[ai.gateway]]
id = "my-gateway"

wrangler secret put CF_API_TOKEN
wrangler secret put OPENAI_API_KEY  # If not using BYOK

Authentication

Gateway Auth (protects gateway access)

const client = new OpenAI({
  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,
  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }
});

Provider Auth Options

1. Unified Billing (keyless) - pay through Cloudflare, no provider key:

const client = new OpenAI({
  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,
  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }
});

Supports: OpenAI, Anthropic, Google AI Studio

2. BYOK - store keys in dashboard (Provider Keys > Add), no key in code

3. Request Headers - pass provider key per request:

const client = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,
  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }
});

API Token Permissions

• Gateway management: AI Gateway - Read + Edit
• Gateway access: AI Gateway - Read (minimum)

Gateway Management API

# List
curl https://api.cloudflare.com/client/v4/accounts/{account_id}/ai-gateway/gateways \
  -H "Authorization: Bearer $CF_API_TOKEN"

# Get
curl .../gateways/{gateway_id}

# Update
curl -X PUT .../gateways/{gateway_id} \
  -d '{"cache_ttl":7200,"rate_limiting_limit":200}'

# Delete
curl -X DELETE .../gateways/{gateway_id}

Getting IDs

• Account ID: Dashboard > Overview > Copy
• Gateway ID: AI Gateway > Gateway name column

Python Example

from openai import OpenAI
import os

client = OpenAI(
    api_key=os.environ.get("OPENAI_API_KEY"),
    base_url=f"https://gateway.ai.cloudflare.com/v1/{os.environ['CF_ACCOUNT_ID']}/{os.environ['GATEWAY_ID']}/openai",
    default_headers={"cf-aig-authorization": f"Bearer {os.environ['CF_API_TOKEN']}"}
)

Best Practices

1. Always authenticate gateways in production
2. Use BYOK or unified billing - secrets out of code
3. Environment-specific gateways - separate dev/staging/prod
4. Set rate limits - prevent runaway costs
5. Enable logging - track usage, debug issues
