Why not poll it yourself?
On a request-priced API, watching a flight means a poller you write, run and keep alive, and somewhere between 70 and 500 requests per flight depending on how nervous you are. The diffing, the signatures, the retries at three in the morning and the log that tells you what was delivered are all yours to build.
Here that is one watched flight. We poll on an adaptive schedule, diff every answer, deliver only the changes, retry when your endpoint is down, and keep the log.
- Poll every 5 minutes for the last 6 hours
- 72 requests
- Poll every 3 minutes for a full day
- 480 requests
- Plus a poller, a differ, a retry queue and a delivery log
- your engineering time
- One watched flight on FlightByte
- 1 line item
Request counts assume one status call per poll. Our own schedule spends roughly 40 to 120 upstream polls per flight, and that cost is inside the price.
How billing works
What counts as a watched flight?
What happens when I reach a limit?
429 with a Retry-After header. Extra watched flights are billed at your plan's overage rate, so a busy month never stops halfway, and nothing already being watched is ever dropped. Free is the exception: the fourth subscription in a month answers 402, and the three you have keep running.How do I pay?
