Payload in → 0-100 quality score, pass/warn/fail, tags and issues before your agent uses it: broken/truncated JSON (auto-repair), JSON Schema mismatch, syntax errors, cut-off code, bot-challenge/captcha/404 scrapes, LLM refusals, placeholders, repetition loops, mojibake, ragged CSV. $0.03/check, deterministic, nothing stored.

Coin (or ALL) → live positioning of ~70 tracked Hyperliquid whales and top-PnL traders: net long/short, smart-money bias, biggest positions with liquidation prices, liquidation-cluster map, funding/OI/premium crowding and squeeze risk. Not investment advice.
