No account, no key. ?view=compact pages the shelf eight at a time. ### An issue GET any issue url without payment for the 402 quote; decode PAYMENT-REQUIRED (base64 JSON), sign the first accepts entry, retry the identical URL with PAYMENT-SIGNATURE and one Idempotency-Key. The issue arrives as text/markdown; PAYMENT-RESPONSE is the receipt. No certificate is minted for a page. ### Pay more if you like The first tier is $25 and that is the price. The two tiers above it buy the same issue and are booked as tips. ## Errors ### 402 Unpaid: the PAYMENT-REQUIRED header carries the terms. Nothing was charged. ### 404 No issue for that week: the week is not on this index. The index is free. ### Settlement failed The payment did not clear and the issue stays shut. No charge; retry with the same payment and idempotency key. ## Security ### What this does in your name Nothing. A GET on the index reads the shelf; a paid GET presents your signed payment to the facilitator once and delivers the issue. ### What it stores about you The purchase record the x402 receipt implies: the exact markdown prepared for your payment, retained for recovery under your private Purchase-Recovery handle. No account, no cookie, no reader list. ### What we never do No account, cookie, caller identifier or IP-based budget. Budgets bound our cost, not caller rank. Requests are never sold, shared or published. The weekly census reads public discovery feeds, never these requests. ### Standards Disclosure is private-first and symmetric: notify the operator before publication, including our own defects. Corrections are dated and public. Signed artifacts verify offline against our published key. ### Reporting https://scvd.store/.well-known/security.txt for a vulnerability, https://scvd.store/corrections for something we got wrong. ## What this is not Not a ranking, not a score on any door, and not a report on any named seller: the issue counts shapes and never names a host that did not consent. Not a subscription either; every issue is bought on its own. ## Checkout ### MPP #### Protocol mpp #### Payment method evm #### Intent charge #### Network eip155:8453 #### Currency USDC #### Amount unit atomic #### Method GET #### Request header Authorization #### Authorization scheme Payment #### Challenge header WWW-Authenticate #### Response header Payment-Receipt #### Idempotency header Idempotency-Key #### Delivery mime type text/markdown #### Per purchase certificate false #### Steps - GET the page's buy_url without payment: the same free quote. WWW-Authenticate carries one Payment challenge per price tier (an RFC 9110 challenge list, minimum first); the first buys the whole page and a higher one is an optional tip. Keep the quote's Idempotency-Key. - Authorize one listed challenge in a compatible MPP client, unchanged. Never combine it with an x402 payment header. Never send private keys, seed phrases or wallet secrets. - Retry the identical URL with Authorization: Payment and the same Idempotency-Key. On success, save the markdown body, the Payment-Receipt header and the private Purchase-Recovery header (base64 JSON). The same credential again returns the retained page without a second settle; an interrupted response does not prove payment failed. ### Buyer guidance #### Price effect - **Higher payment** — optional_tip - **Higher payment changes scope** — false - **Scope** — The entire named page at the lowest offered tier. #### Production - **Kind** — existing_publication - **Attribution** — See the page byline and publication date; purchase does not commission new writing. #### Credit - **Accrues** — false #### Recovery ##### How Retain the exact URL, original signed payment, idempotency key and receipt. Retry the same request; do not sign a fresh payment to check status. ##### Private status handle true ##### Status header Purchase-Recovery ##### Status header encoding base64 JSON ##### Retained good The exact markdown prepared for the original payment; later edits do not replace it. ##### Replay cache seconds 86400 ##### Replay cache limit A cache write or read can fail. Retain the original authorization; do not use a fresh one to recover a missing response. ### Protocol x402 ### Version 2 ### Currency USDC ### Amount unit atomic ### Method GET ### Request header PAYMENT-SIGNATURE ### Challenge header PAYMENT-REQUIRED ### Response header PAYMENT-RESPONSE ### Idempotency header Idempotency-Key ### Delivery mime type text/markdown ### Per purchase certificate false ### Steps - GET the page's buy_url without payment for a free quote. Decode the PAYMENT-REQUIRED header as base64 JSON. - Choose an offered network and amount within your budget. Use accepts[].amount unchanged: it is atomic USDC, not dollars. The lowest tier buys the whole page; higher tiers are optional tips. - Sign in your wallet or payment client. Without a compatible wallet, stop here. Never send private keys, seed phrases or wallet secrets. - Retry the identical URL with the signed x402 v2 payload in PAYMENT-SIGNATURE. Keep one unique Idempotency-Key (16–128 characters) for this purchase and reuse it on retries. - On success, save the markdown body, PAYMENT-RESPONSE header and private Purchase-Recovery header (base64 JSON). The recovery handle retrieves the retained page through a free authenticated status read. No per-purchase certificate is minted for a page. An interrupted response does not prove payment failed; retry with the same payment and idempotency key. ### Documentation URL ## Shelf complete true ## Issues ### Open for Business — 2026-W44 #### Week 2026-W44 #### Date 2026-11-02 #### Teaser 9 agents were refused before paying between 2026-10-26 and 2026-11-01: 1 for a field they left out, 0 for a field in the wrong shape, 0 for pasting the worked example back, and 8 for something other than a field's shape, most often `url`… #### Number of the week 66 of 69 receipt re-checks between 2026-10-26 and 2026-11-01 came more than a week after minting. #### Price USDC 25 #### URL #### Buy URL #### Method GET #### Required params none #### Input schema ##### Type object ##### Properties ##### Required none #### Inputschema ##### Type object ##### Properties ##### Required none ### Open for Business — 2026-W43 #### Week 2026-W43 #### Date 2026-10-26 #### Teaser 63 agents were refused before paying between 2026-10-19 and 2026-10-25: 54 for a field they left out, 0 for a field in the wrong shape, 0 for pasting the worked example back, and 9 for something other than a field's shape, most often `url`… #### Number of the week 109 of 110 receipt re-checks between 2026-10-19 and 2026-10-25 came more than a week after minting. #### Price USDC 25 #### URL #### Buy URL #### Method GET #### Required params none #### Input schema ##### Type object ##### Properties ##### Required none #### Inputschema ##### Type object ##### Properties ##### Required none ### Open for Business — 2026-W42 #### Week 2026-W42 #### Date 2026-10-19 #### Teaser 8 agents were refused before paying between 2026-10-12 and 2026-10-18: 5 for a field they left out, 0 for a field in the wrong shape, 0 for pasting the worked example back, and 3 for something other than a field's shape, most often `url`… #### Number of the week 86 of 101 receipt re-checks between 2026-10-12 and 2026-10-18 came more than a week after minting. #### Price USDC 25 #### URL #### Buy URL #### Method GET #### Required params none #### Input schema ##### Type object ##### Properties ##### Required none #### Inputschema ##### Type object ##### Properties ##### Required none ### Open for Business — 2026-W41 #### Week 2026-W41 #### Date 2026-10-12 #### Teaser 58 agents were refused before paying between 2026-10-05 and 2026-10-11: 52 for a field they left out, 0 for a field in the wrong shape, 0 for pasting the worked example back, and 6 for something other than a field's shape, most often `url`… #### Number of the week 267 of 298 receipt re-checks between 2026-10-05 and 2026-10-11 came more than a week after minting. #### Price USDC 25 #### URL #### Buy URL #### Method GET #### Required params none #### Input schema ##### Type object ##### Properties ##### Required none #### Inputschema ##### Type object ##### Properties ##### Required none ### Open for Business — 2026-W40 #### Week 2026-W40 #### Date 2026-09-28 #### Teaser The week in agent buying, from the till at scvd.store and the doors it probes.
