get_pow_ : Too Many Requests (HTTP 429)

[samueltsw]

Hi,

A few days ago, I was able to pull data from POWO using get_pow_ by inputting a vector of scientific names.
powo_data <- get_pow_(unlist(test_data_unique), messages = FALSE)

However, there are errors even I am just trying to pull one scientific name. It seems to be related to the rate limits mentioned in #598
Error: Too Many Requests (HTTP 429) & Error: Bad Gateway (HTTP 502).

Update:
I use a for loop instead to pull data with the use of trycatchand sys.sleep and it's okay now.

Thanks,
Samuel

Thanks for the issue @samueltsw Yes, its related to that issue - and see #598 (comment) - i'll add that information on rate limits to the docs.

your solution is the one i'd use too, sys.sleep between requests

note that they may change rate limits through time, so code that works now may work differently in the future (i.e., need to add more sleep time, or could use less, depending on whether they decreased or increased rate limit)
