Fields
agent_id, profile_url, and, from 12 October, history_url identify LocalMark pages. card_url, endpoint_url, also_published_at, publisher_domain, and publisher_declared describe what the publisher advertised. The publisher_declared object contains name, protocol version, and short skill labels and tags. Full card descriptions are omitted.
observations contains LocalMark's first-listed and last-verified times, signature status, latest card check, 30-day card-check totals, endpoint TLS result, and read-only A2A probe result. Snapshots from 12 October also add a normalized A2A version family, a probe reason code, last confirmed card-change time, claim status, public quality flag names, and x402 check state. These are point-in-time checks, not proof of task performance or a provider's identity. also_observed_in lists external public indexes where LocalMark encountered that card URL, with the last time observed. It does not establish that the source still lists the card or that publishers share ownership.

Publisher-supplied names, skill labels, links, endpoints, and Agent Card details are reproduced as published.

Each JSON Lines record repeats the licence scope so it travels with the data.
Corrections and removal
Listings removed on request are excluded from later snapshots. Earlier snapshots and copies already downloaded elsewhere are not rewritten. To request a correction or removal, email support@localmark.ai with the card URL. Read our privacy notice for personal data requests.
