How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
A JSON object containing the queried ticker, a list of related ticker symbols (e.g. ['MSFT','AMZN','GOOGL','NVDA','META']), a count of related tickers, and an as-of timestamp indicating data freshness.
Example use cases
Build watchlist around NVDA
“Can you find me a list of stocks that are closely related to NVDA? I want to build a watchlist of similar names that tend to move with it.”
Peer comparison screen for Tesla
“I'm doing a peer comparison on Tesla — what other stocks are most closely related to TSLA that I should be looking at alongside it?”
Diversification check against SPY
“I already hold SPY in my portfolio — what other ETFs or stocks are highly correlated with it so I can avoid doubling up on the same exposure?”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/related/%7Bticker%7DWhen to prefer
Use this endpoint when you need to discover stocks that are correlated with or peer to a given ticker — ideal for building watchlists, peer comparison screens, or diversification analysis. Prefer this over general market search endpoints when you already have a specific ticker and want to find its market relatives without manually curating peer groups.

- Ticker not found in the database returns a 404 or empty data response
