Policies

Backoff Strategy
Clients should implement exponential backoff with jitter when receiving 429 responses, honoring the Retry-After header when present.
Burst Handling
Short bursts above the steady-state per-minute limit may be tolerated up to the burst ceiling before throttling engages.
Quota Reset
Monthly quotas reset at the start of each calendar month. Per-minute windows reset on a rolling basis.
Key Parameter
The API key is passed as the `key` query parameter on all requests to the free.rome2rio.com endpoint. Example — /api/1.4/json/Search?key=YOUR_KEY.
