Hi, I have a question about your API (https://blockchain.info/api/blockchain_api). I often get the HTTP 429 Too many requests response. I use your API to parse the blockchain. I didn't find any API usage limits on your website but apparently I'm successful in hitting them. Could you please tell me how many requests I'm allowed to do per second or minute?

Requests in 8 Hours: 3 (Soft Limit = 28800, Hard Limit = 28900)
Requests in 5 minutes: 2 (Soft Limit = 700, Hard Limit = 725)
