How this service works
Bitcoin Gold correlation API: 14-day rolling Pearson correlation between BTC and gold spot. Returns rho, regime (LIQUIDITY_STRONG, LIQUIDITY_MILD, DECOUPLED, HEDGE_MILD, HEDGE_STRONG), interpretation. Cross-asset macro signal for risk-on/risk-off rotation strategies and AI agents tracking BTC's behavior as digital gold versus risk asset.
Output
Returns a JSON object with rho_14d (Pearson correlation coefficient over the last 14 days), a regime label (one of LIQUIDITY_STRONG, LIQUIDITY_MILD, DECOUPLED, HEDGE_MILD, HEDGE_STRONG), a human-readable interpretation string, the window_days value (14), and an updated_at timestamp indicating data freshness.
Example use cases
Example prompt
“What's the current 14-day Pearson correlation between Bitcoin and gold — is BTC in a hedge or liquidity-driven regime right now, and what does the interpretation say about its behavior as digital gold versus a risk asset?”
Technical details
Endpoint
GEThttps://nonvisceral-eloisa-mousily.ngrok-free.dev/api/btc-gold-correlationWhen to prefer
Use this endpoint when you need a quantitative, rolling cross-asset correlation signal between BTC and gold to classify Bitcoin's macro regime (hedge vs liquidity/risk asset). Prefer this over generic price feeds when you need the regime label and interpretation ready for decision logic in rotation strategies, risk-on/risk-off signals, or when building AI agents that must reason about BTC's role in a macro portfolio. It complements the sibling BTC/ETH regime direction and liquidation endpoints on the same host for a bundled macro signal.
Side effects
- Upstream price data unavailable — may return stale or error response
- ngrok tunnel down or unreachable — HTTP 502 or connection timeout
- No data for sufficient 14-day window — may return null rho or partial result
- Rate limit or payment validation failure — HTTP 402 if x402 payment not processed correctly
