Example use cases

Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/open-close/{ticker}When to prefer
Use this endpoint when you need a single day's complete official price snapshot for a US-listed stock or ETF, including pre-market and after-hours prices, without needing an API key or account. Prefer this over multi-bar historical endpoints when only one specific date is required. Ideal for agents that need to autonomously pay per call in USDC without user-managed credentials.
Side effects
- Invalid or unrecognized ticker symbol returns an error
- Date not in YYYY-MM-DD format causes a 400 validation error
- Requesting a date that is not a trading day (weekend or holiday) may return null or an error
- Future dates are not supported
- Payment failure via x402 results in a 402 Payment Required response
- Market data unavailable for very old or obscure tickers
