Agent skills that fact-check the internet: claim-by-claim verification with sources and a 0-10 BS score for any YouTube video, article, tweet, or PDF

Continuously updated paper list on advancements in Data Agents. Companion repo to our paper "A Survey of Data Agents: Emerging Paradigm or Overstated Hype?"

A style gate for marketing copy that enforces concrete claims via a Python linter and Claude Code/Codex session hooks.

Query historical and real-time crypto market data from 0xArchive across two top-level venue APIs: Hyperliquid and Lighter.xyz. HIP-3 builder perps live under the Hyperliquid namespace at /v1/hyperliquid/hip3. HIP-4 outcome markets (binary prediction markets like 'Will BTC be >= X by date Y?') live at /v1/hyperliquid/hip4. Hyperliquid Spot lives at /v1/hyperliquid/spot with 326 authenticated inventory rows (HYPE-USDC, PURR-USDC, AAPL-USDC, ...); Spot candles are served from 2025-03-22T10:50:22Z. Covers route-specific orderbooks, trades, candles, funding rates, open interest, liquidations, outcome markets, spot, TWAP, and data quality. Real-time WebSocket support is channel-specific. HIP-4 trades, L4 events, and settlement events are live; HIP-4 L2 orderbook and outcome-side OI remain available through REST and stored replay while their live bridges are paused. Use in Claude Code, Codex with skills enabled, and SKILL.md-compatible agents when the user asks about crypto market data, order
