How EXIPRA works

Overview and fees

EXIPRA is a marketplace where product ideas and designs are sold as design documents. The seller chooses what is public; everyone can read the public part, and the rest becomes readable after purchase, on grant.

Payment goes directly from buyer to seller — EXIPRA never holds funds. EXIPRA currently takes no fee from sales.Any future fee will be announced in advance and apply only to transactions concluded after the announced date (Terms, Article 7). When card (Stripe) or PayPal is used, the payment provider's processing fee applies on the seller's side under the seller's own agreement with that provider. Direct payment (bank transfer, etc.) involves no EXIPRA-side cost.

Selling

  1. Create an account and set up at least one way to receive payments on "Payout rails" (/me/rails): Stripe, PayPal, or payment instructions for direct payment.
  2. From "Publish", upload or paste a Markdown design document. Toggle each section public or paid, and check the buyer preview.
  3. Set the title, category, price and "What you get", then publish. There is no screening. Drafts can be saved.
  4. Purchase requests appear under "Sales" on your account page. Card and PayPal grant automatically on successful payment. On the direct-payment rail, verify the payment yourself and record either "Grant" or "Could not verify the payment" within 72 hours of the buyer's payment declaration.
  5. You can withdraw a listing at any time (buyers who already purchased keep access).

Buying

  1. Open a design from the listing or search. The public sections, the titles of the non-public sections, "What you get", the price and the payment methods are all visible before purchase.
  2. Choose a payment method under "Request purchase". Card (Stripe) and PayPal proceed to checkout, and the full document is granted automatically on successful payment.
  3. For direct payment (bank transfer, etc.), the seller's payment instructions are shown. Pay as instructed, then record "I paid" on the transaction page; the document is granted after the seller verifies the payment.
  4. After grant, download the full document from the transaction page.

Transaction states and deadlines

  • A purchase request (REQUESTED) with no activity for 30 days is recorded as cancelled.
  • The seller's response deadline after a payment declaration (PAID DECLARED) is 72 hours. A missed deadline is recorded as EXPIRED on the seller's record.
  • Granted transactions remain downloadable.

The isolation-verified badge

The badge on a design page is a statement of fact: the preview passed a publish process that verified, by measurement, that non-public content did not reach the judging AI. It appears only while the published disclosure matches the judged line, and the judgment is a snapshot of the model at judging time. See "Use EXIPRA from your AI tools" for details.

Using EXIPRA from AI tools

Search, purchase and publishing also work from Claude, ChatGPT, Claude Code and Codex CLI (connection guide). To turn a chat conversation into a listing, see "Sell from a chat conversation".
