Which one, for what

Cloudflare AI Gateway B

Good for Teams that already hold a Cloudflare account and want one token, one bill, logs, budgets and fallbacks in front of several model providers, or that want to keep their own provider keys behind a proxy with spend limits.

Ahead on

  • Reliability, 66 against 55
  • Security & auth, 75 against 60
  • Payments & pricing, 52 against 40

Watch for

API tokens are account-scoped. Any token with AI Gateway Run can send requests through every gateway in the account and spend its stored provider keys

OpenRouter B

Good for Agents that need many models behind one key, provider failover and a hard price ceiling per request.

Ahead on

  • Schema & documentation, 90 against 75
  • Agent ergonomics, 85 against 73
  • Maintenance & community, 84 against 75

Also in its favour

  • Free to start without a card
  • No incidents deducted, where Cloudflare AI Gateway loses 3 points for them

Watch for

No machine payment. USDC top-ups go to a prepaid balance

Before you call either

Cloudflare AI Gateway

  1. Use the REST API at api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1 with a token holding Workers AI Read. A token with only an AI Gateway permission returns 401 with code 10000
  2. Send cf-aig-gateway-id on every Workers AI (@cf/) call and on dynamic routes. Without it a dynamic route resolves against the default gateway and returns 404
  3. Set cf-aig-collect-log: false or cf-aig-collect-log-payload: false on sensitive requests. Logging of prompts and responses is on by default
  4. Treat a 429 as a rate limit or a spent budget and a 401 with code 2009 as a rejected provider key. Do not retry a 2009
  5. Set byok_only on the gateway or send cf-aig-no-wholesale: true to stop a request without a provider key falling through to paid Unified Billing credits

OpenRouter

  1. Set provider.data_collection: "deny" or provider.zdr: true when the prompt holds anything private
  2. Pass a models list so a failed provider falls through to the next one
  3. Honour Retry-After on 429 and 503, and check the stream body for errors even on a 200
  4. Set max_price so a routed request can't land on an expensive provider
  5. Free models allow 50 requests a day until $10 of credit has been bought. Check GET /api/v1/key for what's left
