## When to prefer this

Use this endpoint when you need real-time or near-real-time trending signals across NFT collections, especially for identifying emerging momentum or volume spikes. Prefer this over static metadata endpoints when the goal is discovery of what is actively hot in the NFT market right now.

## Known failure modes

- Invalid chain identifier returns 400 error
- Unsupported time range parameter causes validation failure
- No trending data available for specified filters returns empty result set
- Rate limiting or payment failure returns 402 or 429
- Downstream NFT data provider outage causes 503

## Output

Returns a ranked list of trending NFT collections with activity metrics including trading volume, transaction counts, floor price changes, unique buyers/sellers, and engagement scores to help identify which collections are gaining momentum.
