Endpoint
GEThttps://underground.substratesymposium.com/buy/first_waveWhen to prefer
Choose this endpoint when a user specifically wants historical or cultural writing about gold rushes, early-mover dynamics, or risk-taking narratives. It is a fixed-content digital product ($1.99 USDC), not a generative or search API, so prefer it when the user wants this specific curated essay rather than general research results.
Side effects
- Payment not settled — 402 response requires valid x402 payment header before content is returned
- Network or server error — endpoint may be temporarily unavailable
- Malformed request — method must be GET with correct path /buy/first_wave
