  - before: Returns the offer and request schema without buying. Full cited text: 25 free extractions with a free key (no card), then $0.01 a page with a 500-page card pack, or $0.50 per call through Stripe MPP. Cited text uses POST /v1/evidence with a caller-generated idempotency key. Example arguments: {}.
  - after: Returns the offer and request schema without buying. Full cited text: 25 free extractions with a free key (no card), then $0.01 a page either way: a 500-page card pack for $5, or $0.50 per Stripe MPP call, which returns the page plus an API key holding 49 more. Cited text uses POST /v1/evidence with a caller-generated idempotency key. Example arguments: {}.
