Derivasys changelog.

• Published the public daily-data REST API for BTC, ETH, SOL, XRP, HYPE, AVAX and TRX with no account or API key requirement.
• Added currency and date discovery, latest and dated observations, and paginated date-range queries preserving published provenance and unavailable values.
• Added a quickstart and API reference at /api/data/, linked from the data archive, asset histories, homepage and navigation. Live surface evaluation remains a separate offering.

Changed

• Corrected 8 October realised-volatility measurements using recovered one-minute index-price history at the original report cutoff. Correction notices retain the original publication time and link the previous artifact.
• Made monthly report archive snapshot summaries use the corrected structured market read when a verified correction supersedes the original summary.
• Added canonical JSON and CSV report datasets under /data, preserving measurement units, source provenance and unavailable values.
• Added /sitemap-status to show the checked availability, freshness and URL counts of the main, news and data sitemaps.

Changed

• Updated the public /live route so its What matters now summary and reviewed source stories appear before raw signals.
• Kept the seven-market overview flat and removed duplicate cross-asset event rows so a qualifying event has one grouped overview item.
• Added evidence-linked report observations on the published daily, major-coins, altcoins, weekly and weekly cross-asset report routes.

Changed

• Added permanent monthly report archives at /reports/archive/[month], with links from the published BTC, ETH, SOL, major-coins, altcoins and weekly report collections.

Changed

• Added the weekly cross-asset report archive at /reports/weekly/cross-asset for aligned BTC, ETH, SOL, XRP, HYPE, AVAX and TRX options comparisons.

Changed

• Moved XRP, Hyperliquid HYPE, Avalanche AVAX and Tron TRX into verified live production coverage alongside BTC, ETH and SOL.
• Added a dedicated altcoin options volatility surface page with market-specific search intent, structured data and dashboard deep links.

• Updated the shared product registry, homepage metadata, current product documentation, contact copy, footer and sitemap-derived content manifest for seven live markets.
