Max input size
- 14,336 Unicode characters.
- It includes whitespace characters and any markup characters such as HTML or XML tags.
- There is no rate limit except Keyword Suggestion API, which is 2 requests per 10 seconds.
- If you exceed the rate limit, you will get “Too many requests. Try again in a few seconds.” error messages.
- Normally our server can handle 6 requests per second. In case of more traffic, our server automatically scales up to more than 300 requests per second.
- However, the scaling happens periodically. This means, if you send 100 requests per second immediately, many requests will fail. Instead, we recommend to start out at 6 requests per second, and to increase the amount of requests per second every 3 minutes by 6 requests. For example, going from 6 to 12 requests per second after 3 minutes have passed. In this case, you will consume 6 requests per second * 60 seconds * 3 minutes = 1,080 requests.
- Please keep in mind that in case you stop sending requests, the server will go back to the original capacity of 6 requests per second.
