Limits
Async Job Concurrency account
not publicly documented
Use the returned polling_url; do not construct your own polling URL.

Policies
Backoff Strategy
Clients should implement exponential backoff with jitter and honor any Retry-After header.
Polling Discipline
Always use the polling_url returned in the response rather than constructing one client-side.
Regional Routing
Choose the EU or US regional endpoint to control data residency and latency.
