## 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

## Verdicts

**Cloudflare AI Gateway.** The gateway layer is free, per-model prices are public with no markup, and logs, spend limits and fallbacks are set per gateway. API tokens cannot be limited to one gateway, the service terms take third-party models outside Cloudflare's DPA, no SLA names the product, and error codes changed on 6 October 2026 with same-day notice.

**OpenRouter.** Public OpenAPI document, llms.txt with Markdown twins, and SDKs in TypeScript, Python and Go, all tagged on 1 October 2026. 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
