The US government runs PACER itself, they don't contract it to a profit-motivated third-party. [1] As a result, they're pretty lenient. At one point, their website said: "The information gathered from the PACER system is a matter of public record and may be reproduced without permission".
So it's totally legal.
The RECAP people also make it _really_ easy to ingest documents. For example, lawyers can add a RECAP email address as one of their default contact addresses with the court. Then all filings on any case that lawyer is involved in get automatically ingested when they are filed.
[1]: Well, they outsource the administration to a third-party. But it seems more like a "we pay you, you keep the lights on", vs a public-private partnership where the third-party has a profit incentive based on the revenue of the service.
