TIMATIC Online (for passport and visa information) [duplicate]

Olympic was the last fully accessible TIMATIC interface AFAIK, so unfortunately you now have to make do with the IATA Travel Centre (not recommended due to the inefficiency and inflexibility) or doing individual searches on e.g. the Emirates site. Sadly don't know any remaining interface offering general searches.

There used to be multiple, such as KLM, but IATA has slowly but surely cracked down on them.

There's IATA's own site at the IATA Travel Centre
