How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
fal stores request inputs and outputs by default. The X-Fal-Store-IO: 0 request header prevents payload storage, but uploaded CDN files can remain accessible and need separate lifecycle handling.
Provider and API links
SpaceXAI says API inputs and outputs are not used for training without explicit permission. Default encrypted retention is 30 days; team-level zero data retention is available with feature tradeoffs.
