Recap (https://free.law/recap/) is a really cool piece of civic tech to work around PACER’s absurd fees. Fantastic news that we could someday be rid of them.
Edit: Also, have you considered going through YC’s non profit pipeline, if only for access to their network and partner resources?
Keep it under $30/quarter and PACER waives the fees.
Anyone else could setup a pacer alternative and just pay for the docs once. I think some legal services even do that.
PACER also includes documents filed by the parties to cases, which don't have the same cut-and-dried nature. A fair use argument probably goes a long way here but that's always more uncertain.
