Endpoint
GEThttps://blockrun.ai/api/v1/stocks/us/price/AAPL?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time US equity prices sourced from the Pyth Network oracle with a confidence score, require no long-term API key setup, and want micropayment-per-call billing settled in USDC on Base or Solana. Ideal for AI agents operating autonomously that need verifiable, oracle-backed stock prices without subscription overhead.

- Invalid session enum value returns a 400 bad request
- Payment failure (insufficient USDC balance) returns HTTP 402
- Network or Pyth oracle downtime may result in stale or unavailable price data
- Pre/post-market session requested outside valid hours may return no data
