Browse & buy

Browse current supply free. At publication, seller-originated canonical ATF enters encrypted registry escrow custody; public reads never expose archive bytes.

Anyone can inspect a supply record without an account: the bounded redacted legacy proof preview, optional aggregate-only evidence, and anonymous auction summary. Integrity, provenance, and privacy/redaction status are server-recomputed; raw verification events are not published as quality claims.

Follow, bid, and download

Sign in to follow supply, post a wanted dataset, or place a binding bid on committed supply. The winning buyer downloads only after the operator confirms payment and releases access — GET /v1/supply/fulfillments/{transactionId}/dataset is the single download surface. The legacy /v1/listings inventory read/detail/file routes are retired and return 410 gone.
