Usage of the Tumblr API is rate limited in a few ways, but we respond with a 429 Limit Exceeded
response whenever a consumer hits one of these limits. There is a global rate limit for all usage of the API per consumer, as well as a few per-feature rate limits, such as how many posts you can make per day. The error message or headers you receive with the 429 Limit Exceeded
response should indicate what limit you've hit.
These rate limits include:
- 300 API calls per minute, per IP address.
- 18,000 API calls per hour, per IP address.
- 432,000 API calls per day, per IP address.
- 1,000 API calls per hour, per consumer key.
