How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing: the crypto symbol and its CoinGecko ID, the benchmark used (QQQ), the 90-day correlation coefficient (e.g. 0.5124), a human-readable interpretation (e.g. 'moderate positive'), the sample size of observations, the as-of timestamp, and an optional note field.
Example use cases
Portfolio diversification check
“I'm holding a lot of ETH in my portfolio alongside NASDAQ ETFs — can you tell me how correlated ETH has been to QQQ over the last 90 days so I know if I'm actually diversified?”
Crypto macro regime analysis
“I want to know if Bitcoin is currently trading in sync with the QQQ or if it's decoupled from equities — pull the 90-day correlation for BTC and tell me what the interpretation is.”
Alt-coin risk assessment
“Before I add Solana to my fund, can you check how correlated SOL is to QQQ right now? I want to know the coefficient and whether it's a moderate or strong relationship.”
Technical details
Endpoint
GEThttps://x402financialdata.com/crypto-correlation/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need a fast, pay-per-call (no API key or subscription) statistical correlation between a specific cryptocurrency and the QQQ equity benchmark. Ideal for agents performing portfolio analysis, macro regime detection, or risk assessment without a standing data subscription. Prefer over general financial data APIs when you need crypto-to-equity correlation specifically and want micro-payment billing via x402/USDC.
Side effects
- Unknown or unsupported crypto symbol returns an error or null data
- Payment of $0.01 USDC not completed results in HTTP 402 response
- Network issues on Base or Solana blockchain may delay payment settlement
- Insufficient historical data for a newly listed token may reduce sample size or return null
- Malformed symbol path parameter returns a 400 or 404 error
