## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.02 USDC) structured digest of Solana ecosystem headlines tagged by activity lane, without needing full article content or deep analysis. Ideal for monitoring dashboards, newsletter pipelines, or agent workflows that need a quick 24-hour pulse of the Solana ecosystem rather than raw social data or full news articles.

## Known failure modes

- Missing required 'ecosystem' query param — validation error returned
- Missing required 'window' query param — schema validation failure
- Invalid lane value — may return empty results or an error
- Payment not provided or insufficient — x402 payment required error
- Service cold-start latency on Render free tier — slow first response or timeout
- No headlines available for the requested lanes — empty result set returned
