# nasdaq-quote-api — validation only

https://api.nasdaq.com/api/quote/<SYMBOL>/info?assetclass=stocks|etf — the JSON behind nasdaq.com quote pages (delayed).

  • Type: XHR · Rights: PUBLIC_RESTRICTED_REDISTRIBUTION → validator role: the consensus engine excludes it from the canonical value (reason: validation_only) but counts its agreement (validator_count) and flags disagreement (validator_disagrees). Values are never shown or streamed.
  • Family: nasdaq — independent from Cboe, so a Cboe/Nasdaq agreement is a real cross-check for US equities.
  • Timestamps: lastTradeTimestamp like "Sep 12, 2026 4:00 PM ET" or "Sep 10, 2026" (→ 16:00 ET) parsed with parseNasdaqTime.
  • Schedule: every 5 min while Nasdaq is open (0.5 req/s → full universe in ~2.5 min), hourly closed, every 6 h on weekends.
