Questions
What if a request fails?
You are not charged. Payments settle only after a successful response is ready.
Can people buy, not just agents?
Yes. Each dossier page has a "Pay with browser wallet" button.
Is there volume pricing?
Research packs bundle a dossier with the topic's key literature for the same $0.20. For bulk or institutional access, see contact.
