Abstract:

   This document specifies the Verifiable Data Access Contract (VDAC),
   a protocol for cryptographically verifiable bilateral agreement
   between a content publisher and an automated agent regarding the
   terms of programmatic data access. VDAC defines the mechanism by
   which a site issues an access offer, an agent accepts that
   offer, both parties sign the resulting contract, and per-request
   references bind individual interactions to agreed terms.

   VDAC is the protocol-layer realization of the bilateral commitment
   principle introduced in Section 6.6 of the Verifiable Identity
   Claims and Delegation Model [VICDM] and operates as a companion
   specification to the Signed Agent Identity Protocol [SAIP].

   This document defines mechanism, not content: VDAC verifies the
   existence and integrity of an agreement; the substance of what is
   agreed remains entirely between the contracting parties.

   VDAC also defines an append-only contract history. Changes to the
   recorded state of a Contract are recorded as signed change records
   and associated immutable snapshots; the original Contract Document
   is never modified.
