When you sign up for a free developer account, you get 100 free requests.If you need to make more requests, please upgrade to a paid plan. When upgrading, you can confirm your quota by looking at the x-api-key-quota response header. To see your current month’s usage, look for the x-api-key-approximate-usage response header.We will also send you an email warning you upon reaching 80% of your quota. The API will return an HTTP status code 429 when the quota has been reached.In addition to a usage quota we also apply a request throughput limit to protect our service from abuse. By default, throughput is limited to a sustained 100 requests/second with some flexibility to accommodate bursts (30,000 requests / rolling 5 minute hard limit). You’ll receive an HTTP status code 429 when you exceed this limit.If your use-case requires higher throughput limits, contact us.
