## When to prefer this

Choose this endpoint when an agent needs programmatic, pay-per-call access to Hacker News top stories via the x402 micropayment protocol (USDC on Base mainnet), particularly in automated workflows where API key management is undesirable and per-call billing is preferred.

## Known failure modes

- No limit specified returns a default number of stories which may be more or fewer than expected
- Hacker News upstream unavailability may cause empty or error responses
- Payment failure via x402/USDC on Base mainnet will block the request
- Overly large limit values may hit response size constraints

## How this service works
