Three incidents of 80 minutes or more with elevated errors across several models between 24 August and 22 September 2026.\n\n**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.\n\n## Before you call either\n\n### Claude API\n\n1. Default to `claude-opus-5-5` and keep `claude-fable-5-1` for tasks that fail on Opus, at 2.5 times the price\n2. Don't send `tool_choice` any or tool to Opus 5.5, Sonnet 5.5 or Fable 5.1. Use auto with `strict: true` on the tool\n3. Put `cache_control` on the system prompt and tool list. Reads cost 0.05x input on Opus 5.5\n4. Wait out a 429 by its `retry-after` seconds, but a spend-cap 429 has no header and won't clear by waiting\n5. Move off `claude-sonnet-4-5-20250929` before 2026-11-30. Retired ids fail, they don't redirect\n\n### Cloudflare AI Gateway\n\n1. 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\n2. 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\n3. 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\n4. 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\n5. 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\n\n## Questions\n\n### Which is better for AI agents, Claude API or Cloudflare AI Gateway?\n\nClaude API scores 77.3 (BB) on agent readiness against Cloudflare AI Gateway's 66.8 (B), and leads in 5 of 7 scored categories. Cloudflare AI Gateway leads on reliability and payments \u0026 pricing.\n\n### Do Claude API and Cloudflare AI Gateway need an API key?\n\nBoth need an API key.\n\n### Can an agent call Claude API and Cloudflare AI Gateway without installing anything?\n\nYes. Claude API has a hosted endpoint at https://api.anthropic.com/v1/messages and Cloudflare AI Gateway at https://api.cloudflare.com/client/v4/accounts/{account_id}/ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/anthropic-api-vs-cloudflare-ai-gateway.json, and with the fewest tokens: https://www.anchorterminal.com/compare/anthropic-api-vs-cloudflare-ai-gateway.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"anthropic-api\", \"b\": \"cloudflare-ai-gateway\"}`.
