Use ProofFetch only for lawful retrieval of public resources. Do not use it to evade access controls, authenticate to third-party services, or access private networks. Paid fulfillment covers the exact successful response bound to its machine-payment receipt. Prices: a card pack is $5.00 for 500 successful extractions ($0.01 a page); a $0.50 payment through Stripe MPP buys 50 successful extractions: the page requested plus an API key for 49 more. A ProofFetch key covers the stated number of successful extractions; each successful extraction uses one credit and failed fetches use none. Free keys: a free key costs nothing and holds 25 successful extractions, used the same way as paid credits (failed fetches use none). It is separate from paid credits and is not topped up; when it runs out, buy a card pack. One free key per network per month, and at most 200 free keys are issued each day across all users. We may revoke free keys used to get around these limits.
