Source OpenAPI: 0xArchive API 1.5.0; 140 paths; 119 component schemas. Get mark/mid price history for a HIP-4 outcome side. Lightweight projection of open interest data. Note: mark_price for HIP-4 outcomes is an implied probability in [0,1], not a USD price; same field name as perps because Hyperliquid upstream uses markPx for both. oracle_price is omitted for HIP-4 (outcomes have no oracle feed).
