Why curated JSON beats raw APIs

Raw exchange APIs return data dumps. 402crypto returns intelligence — pre-computed, cross-validated, and annotated for LLM reasoning.

Raw Exchange API

{
  "symbol": "BTC",
  "interval": "1h",
  "data": [[1710892800, 67234.5, 67890.2, ...]]

  // Single timeframe, single source
  // No reliability information
  // No known limitations
  // You compute everything yourself
  // You handle stale data yourself
}
