Rate limiting is only forced for unauthenticated accounts with a limit of 2 requests per minutes. Once authenticated, you can convert up to 250 documents per minute (10 only if you use the sandbox mode). When reaching the rate limit, you will get an HTTP status code of 429. Each request will contain three headers to let you know your usage:
​
X-RateLimit-Remaining
Integer
Indicates the number of requests before hitting the rate limit.
​
X-RateLimit-Limit
Integer
Indicates the number of requests you can make per minutes.
​
X-RateLimit-Reset
Integer
Represents a timestamp in seconds. Indicates when the rate limit will reset.
