verify_assetread-onlyReturn the canonical on-chain verification verdict for a TAG IT physical asset: its lifecycle state (MINTED, BOUND, ACTIVATED, CLAIMED, FLAGGED, RECYCLED), whether that state counts as authentic, and a re-derivable chain reference. Byte-identical to the public JSON at GET https://verify.tagit.network/api/asset/{token_id}. IMPORTANT LIMIT: `authentic` is a claim about LIFECYCLE STATE ONLY. It is no
get_lifecycle_historyread-onlyReturn the ordered on-chain event timeline for a TAG IT asset, oldest first: mint, NFC tag binding, every state transition, and every resale. Each event carries the block number and transaction hash that produced it, so any entry can be re-derived independently from a Base Sepolia node. Addresses are returned as domain-separated commitments, never raw. IMPORTANT: check the `available` field. When
check_flaggedread-onlyFast yes/no on whether a TAG IT asset is currently FLAGGED — TAGITCore lifecycle state 5, meaning an open lost / stolen / recall investigation. IMPORTANT: `flagged: false` does NOT mean the asset is in good standing. RECYCLED (end-of-life) and unminted assets are also not flagged. Always read the `state` and `authentic` fields returned alongside it before treating a negative as a pass.
