Endpoint
GEThttps://blockrun-web-vbsbhh7lea-uc.a.run.app/api/v1/stocks/us/price/SPYWhen to prefer
Use this endpoint when you need a real-time, high-confidence price for the SPY ETF specifically, with Pyth Network provenance and optional pre/post market session support. Prefer over aggregator APIs when you need a cryptographically-sourced price feed ID alongside the quote.
Side effects
- Invalid or unsupported ticker symbol returns an error
- Market closed with no session parameter may return stale or unavailable data
- Invalid session enum value (not 'pre', 'post', or 'on') causes a validation error
- Payment failure (insufficient USDC) results in HTTP 402
- Network timeout or Pyth feed unavailability causes service error
