  Full detail for one order including a FRESH live-contents snapshot (principal, claimable rewards, voting/earning power, as_of_block).
• get_listings ~306 tokens
  Active listings/auctions for a market. Each row carries the ask and the position's underlying contents priced at current market (published formula: /docs#data-sources), plus discountPct (the difference between them). Sorted by discount percentage, descending.
• get_orders ~130 tokens
  List orders created by an address (its listings, auctions, offers). Status is reconciled by the background worker — treat as advisory until checked at fill.
• get_owned_positions ~107 tokens
  List the positions an address owns in a market, with listability (voted/attached positions can't transfer).
• get_recent_trades ~172 tokens
  Recently settled sales for a market. `amount` is the EXACT settled total (incl. fee) from the on-chain fill where the indexer recorded it, with `settledAt` the block time and `exact: true`; otherwise it falls back to the listed ask with `exact: false` (a decayed Dutch auction settles BELOW its liste
