Why this limit matters

OpenAI: o3 RPM limit decides whether a key can enter a production route. TestKey reads model ID openai/o3, provider OpenAI, catalog context, real-key headers, 429 errors, and region signals together.

How to prove it

Read-only check. Detection data burns after 5 minutes.

Start with the visible signal: real key probe required, then read headers and error bodies with read-only requests.
RPM limit must bind model ID openai/o3; limits from another model at the same provider cannot be reused.
