This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

Explainability primitive only \u2014 NOT a detector verdict, identity/control assertion, AML decision, or legal advice. window_from present means the answer was built from that date, the edge-grain horizon, not from the start of the requested window; the default window all, 90d and 1y included (/v1/methodology edge_grain_horizon). When window_from is present, read the graph as covering that span only \u2014 do not treat the absence of a counterparty, a path or a sanctioned node as evidence about anything before that date. volume on nodes is the token's raw minor units (divide by 10^decimals); volume_usd6 is the same amount in USD with 6 decimals at peg 1. On Solana (chain -1) the answer carries coverage_status for the subject address only, never for its counterparties: pending \u2014 its history is still being filled, so an empty or small answer is not final; partial \u2014 filled to a documented bound. The walk shows a finished fill after the next Solana rollup pass (about 10 minutes), and never shows history older than window_from. This read never starts a fill, so pending can also mean none was asked for yet: one compliance read of the address asks for it. A Solana answer without coverage_status could not read it in time \u2014 treat it as pending. On Solana (chain -1) the edge grain of 2026-07-20..2026-09-14 is incomplete: those days hold part of their transfers or none, because their raw rows were offloaded before a fix reached production on 2026-09-17; they are not restored, and answers do not mark them (decision of 2026-09-17). Solana's grain is never trimmed, so there the horizon that window_from reports is not where retained data ends: once window_from is later than 2026-09-14 the answer holds none of those days. An answer that reaches them \u2014 window_from on or before 2026-09-14, or no window_from over a window that includes them \u2014 counts them as floors: at least this much, never the whole, and a counterparty, path or sanctioned node missing from those days is not evidence that there was none.",

Surrounding whitespace, a leading + and leading zeros are ignored, a JSON number counts by its value (1.0 is 1), slugs and CAIP-2 ids match in any letter case, and an empty, blank or null chain is no chain at all.

Without chain, the address's spelling picks it: 0x\u2026 \u2192 8453 Base, T\u2026 \u2192 Tron, base58 \u2192 Solana. The answer states the chain it is about (chain_id) and how it was chosen (chain_source: explicit|default|address_form), and lists where else this address has data (chains_with_data) \u2014 read that map before concluding; there is no auto-switch, ask again with chain set.",
