## When to prefer this

Choose this endpoint when you need a pre-ranked feed of currently trending Base network tokens with associated risk scores, especially for AI trading agents that need to combine momentum signals with onchain risk intelligence in a single pay-per-call call. Prefer it over generic token screeners when operating specifically on Base and needing quantified risk scores rather than just price or volume data.

## Known failure modes

- Invalid limit parameter returns an error or default behavior
- Payment not processed (x402 payment required) returns 402 status
- Base network data unavailable causes empty or stale token list
- Limit value too large may return fewer results than requested
