Integration guides for Claude Code, Codex, OpenCode and CC Switch, plus how usage and billing are recorded on ROIBest AI.https://ai.roibest.com/enhttps://ai.roibest.com/blog/claude-code-setup/https://ai.roibest.com/blog/claude-code-setup/Pointing Claude Code at ROIBest AI takes two environment variables. What actually trips people up is picking the wrong protocol group for the key, and adding /v1 to ANTHROPIC_BASE_URL — one curl call catches both.Fri, 07 Aug 2026 11:58:28 GMThttps://ai.roibest.com/blog/codex-setup/https://ai.roibest.com/blog/codex-setup/Codex speaks the OpenAI protocol, so the key, the endpoint and the config format all differ from Claude Code: an OpenAI-compatible key, a base_url that does include /v1, and settings in config.toml rather than environment variables.Fri, 07 Aug 2026 01:00:00 GMThttps://ai.roibest.com/blog/sdk-and-curl/https://ai.roibest.com/blog/sdk-and-curl/The official SDKs need no code changes — only a different base URL and key. Here are all the endpoints the gateway exposes, plus the most common source of 404s: the OpenAI SDK wants /v1, the Anthropic SDK does not.Thu, 06 Aug 2026 03:00:00 GMThttps://ai.roibest.com/blog/cc-switch-import/https://ai.roibest.com/blog/cc-switch-import/Manual setup is not hard, it is just easy to mistype. The import flow generates config that matches the key's own protocol group, taking the two easiest mistakes — group mismatch and the /v1 suffix — off your hands.Thu, 06 Aug 2026 02:00:00 GMThttps://ai.roibest.com/blog/usage-records-explained/https://ai.roibest.com/blog/usage-records-explained/The console records usage per request. This is what each column means, and where to look first when a call costs more than the last one — most of the variance comes down to model, output length and cache hits.Wed, 05 Aug 2026 03:00:00 GMThttps://ai.roibest.com/blog/api-key-quota-expiry/https://ai.roibest.com/blog/api-key-quota-expiry/One account can issue many keys, each with its own quota and expiry. This is not just access control — it is the cheapest way to turn 'who spent what' from one opaque bill into readable data.Wed, 05 Aug 2026 02:00:00 GMT
