Common responses

All error responses include a request_id — quote it when contacting support. The error envelope follows whichever SDK format you called (OpenAI / Anthropic / Gemini).

200 with empty content

A request can return 200 OK with an empty message — no error, just no text. This is almost always driven by request parameters, not a failure. The most common cause is a max_tokens that is too low for a reasoning (extended-thinking) model: the entire budget is consumed by internal reasoning before any visible output is produced, so the content comes back empty.

On this platform that request typically reports zero token usage and deducts no credits — an empty 200 with an empty usage object is the signature of this case, not a billing bug. Fix it by raising max_tokens so it covers the model's thinking budget plus your expected output, or turn extended thinking off. Always check finish_reason / stop_reason and usage before assuming text exists.
