Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/stock-history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need historical stock price data and want to pay per-call with USDC via the x402 payment protocol, avoiding subscription or API key setup. Ideal for AI agents that need bounded, one-off financial data lookups without managing a brokerage or market data account.
