Translation:
Please include your API key in the request header and set an appropriate timeout for each request.
Alternative phrasing:
Include the API key in the request headers and configure an appropriate timeout for each request.
Notes on word choices:
- "携带" is best rendered as "include" — the standard verb in API documentation (e.g., "Include your API key in the
Authorizationheader") - "合理的" can be "appropriate" or "reasonable"; both are common, though "appropriate" is slightly more formal
- The second version drops "Please" and uses the imperative mood, which is the preferred style in many technical writing guidelines (e.g., Google Developer Documentation Style Guide)
