Aggregates only, no names. ## @context ## @type Dataset ## Name State of the public x402 registry ## Description A weekly running tally of the public x402 discovery list: how many listed doors answer a well-formed payment challenge, how many serve structurally valid signed offers, what the market charges, and how concentrated it is. Aggregates only, no names. ## URL ## License ## Creator - **@type** — Organization - **@id** — - **Name** — SCVD General Store - **URL** — ## Isaccessibleforfree true ## Conditionsofaccess Free to read. No account, no key, no rate limit. ## Corrections URL ## Measurementtechnique One signed GET per declared host per week against the published preflight battery, verifiable in the host's own logs. The walk is capped; where a round hit that cap or lost coverage, the week's coverage block says so. Published by the keeper's hand, never by a clock. ## Variablemeasured ### listed x402 doors probed this round - **@type** — PropertyValue - **Propertyid** — weeks[].probed ### doors answering a well-formed x402 payment challenge (shape only, one vantage) - **@type** — PropertyValue - **Propertyid** — weeks[].ready - **Description** — Not 'working': this is challenge shape, not delivery. ### listed doors serving no valid payment challenge - **@type** — PropertyValue - **Propertyid** — weeks[].rot.pct - **Unittext** — PERCENT ### shape-ready doors serving structurally valid signed offers (JWS parse only, signatures not verified) - **@type** — PropertyValue - **Propertyid** — weeks[].signed_offers.serving ### distinct hosts seen this round - **@type** — PropertyValue - **Propertyid** — weeks[].hosts ### share of doors held by the five largest operators - **@type** — PropertyValue - **Propertyid** — weeks[].top5_share_pct - **Unittext** — PERCENT ### what the round could not see: cap hit, coverage suspect, coverage drop, population denominator #### @type PropertyValue #### Propertyid weeks[].coverage #### Description Absent on weeks measured before this layer existed. Missing means not recorded, never means coverage was fine. ## What this is not NOT a ranking of any operator, no verdict without its derivation and denominator beside it, and not a claim any door is safe to buy from. A verdict is shape-conformance from one vantage at one moment: the census parses signed offers as JWS and does NOT verify their signatures. A door counted as answering is a door that answered our probe, not a door that delivers goods. Weeks whose coverage block is absent were measured before that layer existed — treat missing as NOT MEASURED, never as full coverage. ## How to read Every percentage ships beside the counts it was computed from; use those rather than recomputing against another field. Read each week's coverage block before comparing weeks — a capped round and a quiet week produce the same totals. The weeks array is ascending by ISO week. ## Version 1 ## Weeks ### 2026-W32 #### Observed at 2026-08-09T11:00:44.613Z #### Published at 2026-09-10T00:11:13.143Z #### Probed 39 #### Ready 28 #### Rot - **Dead doors** — 10 - **percent** — 26 #### Signed offers ##### Serving 0 ##### Of ready 28 ##### percent 0 ##### Not found in challenge 28 ##### Present but unparseable 0 ##### Cannot distinguish A door counted in not_found_in_challenge served no extensions['offer-receipt'] offers in the challenge this census read, on the one path it walked.
