Rate limits

Each API key can make 120 requests per minute. Every response tells you where you stand:

Header	Meaning
`X-RateLimit-Limit`	Requests allowed per minute (120)
`X-RateLimit-Remaining`	Requests left in the current minute
`X-RateLimit-Reset`	Seconds until the budget resets

Over the limit, the API returns 429 RATE_LIMITED with a Retry-After header giving the seconds to wait.

Staying under the limit

Page with limit=100 to fetch more per request.
Sync incrementally. Use updated_since or the event feed instead of re-reading everything.
Fetch many deals at once with id (up to 100 IDs per request) instead of one request per deal.
On 429, wait for Retry-After seconds before retrying, and back off if it happens again.

Requests that fail authentication are limited per IP address.
