Policies

Retry-After Compliance
When HTTP 429 is returned, clients must honor the Retry-After response header value (in seconds) before issuing another request.
Exponential Backoff
Clients should implement exponential backoff with jitter when encountering repeated 429 responses beyond the Retry-After window.
Monthly Quota Reset
Monthly transaction quotas reset at the start of each calendar month in UTC.
URL Length Limit
Maximum URL length is 2,048 characters. Query parameters should be kept under 1,500 characters to avoid 404 Not Found errors.
HTTPS Required
All requests must use the HTTPS protocol; HTTP requests are not accepted.
