Technical details
Endpoint
GEThttps://x402broker.com/v1/hackernews-velocity-radar?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time HackerNews trend velocity signals rather than raw story lists — particularly when token efficiency matters (91%+ compression) and you want momentum-ranked results rather than simple chronological or score-based feeds. Ideal for agents that need to monitor fast-breaking tech news without consuming large token budgets.
Side effects
- Empty or null data if no stories match the query filter
- Payment failure if USDC balance is insufficient (x402 payment required)
- Stale data if HackerNews API upstream is slow or rate-limited
- Invalid query parameter causes 400-level error
- Compression artifact reduces fidelity for niche queries
