Google Translation API付费版调用次数及定义技术咨询（Python场景）
Let’s break this down clearly, since it depends on which version of the API you’re using and the size of your comments:
What counts as "one API call"?
For Google’s Translation API (both v2 and v3), a single API call is one HTTP request sent to the API’s endpoint. Each request can include multiple text entries (your comments), but you’re constrained by two key limits per request:
- The maximum number of text items allowed per request
- The total character count across all text items in the request
If you stay within both limits for a request, that’s one API call—regardless of how many individual comments you include (as long as it’s under the item limit).
How many calls for 1000 comments?
This depends on which API version you’re using:
Case 1: Using Translation API v3 (Recommended for Paid Users)
- Per request limits: Up to 1000 text items per request, and a total of 30,000 characters per request.
- So, if your 1000 comments combined are under 30,000 characters, you can send all of them in one single API call.
- If the total character count exceeds 30,000, you’ll need to split the comments into batches where each batch stays under both limits. For example, if each comment averages 40 characters, 1000 would be 40,000 characters—so you’d split into two batches (like 750 comments first, then 250) to stay under the character limit, resulting in 2 API calls.
Case 2: Using Translation API v2 (Legacy)
- Per request limits: Up to 100 text items per request, and a total of 5000 characters per request.
- Even if your comments are short, you’d need at least 10 API calls (since 1000 / 100 = 10). But if the character count per batch exceeds 5000, you’ll need more calls. For example, if each comment is 60 characters, a batch of 100 would be 6000 characters—so you’d split into batches of 83 comments each, leading to ~12 API calls total.
Pro Tip for Python
When using the REST interface directly in Python, structure your request body to include multiple contents entries (for v3) or multiple q parameters (for v2) to batch comments efficiently. Just make sure to validate each batch against the API’s limits to avoid errors.
