How this service works
S&P 500, gold and Nasdaq 100 quotes as the traditional-market leg of a crypto read. BTC trades as a high-beta risk asset far more often than as digital gold, so equities direction is usually the better correlation to check before blaming a crypto-native cause. Priced as ETFs, so use direction and percent change, not the absolute level.
Output
Returns ETF-priced quotes for S&P 500 (SPY), Nasdaq 100 (QQQ), and gold (GLD) including current price and percent change. Intended for directional and percentage-change analysis rather than absolute price levels, since these are ETF proxies rather than the underlying indices.
Example use cases
Crypto drop root cause check
“ETH just dropped 4% — grab the S&P 500, Nasdaq, and gold quotes so I can tell whether this is a macro equities selloff dragging crypto down or a crypto-native event.”
Morning macro briefing for crypto trader
“Give me a quick snapshot of where S&P 500, Nasdaq 100, and gold are trading right now so I know the traditional market backdrop before I look at crypto prices this morning.”
Risk-on vs risk-off regime filter
“Are we in a risk-on or risk-off environment today? Check the S&P 500 and Nasdaq 100 direction and percent change for me.”

Endpoint
POSThttps://asistent-crypto.vercel.app/api/x402/data/tradfi-quotesWhen to prefer
Choose this endpoint when you need to contextualize a crypto price move against traditional market conditions, specifically to check whether BTC/ETH selling is correlated with a broad equities selloff rather than a crypto-native cause. Prefer this over general market data APIs when you are already working within the asistent-crypto.vercel.app ecosystem and want a single pay-per-call call covering S&P 500, Nasdaq 100, and gold together as a macro regime snapshot.
