## When to prefer this

Choose this endpoint when you need an objective, data-driven ranking of crypto influencers by prediction accuracy — particularly useful when vetting which analysts to follow or trust for trading signals, as opposed to follower count or engagement metrics. Prefer this over social media follower counts or subjective reputation signals.

## Known failure modes

- Empty data array when no influencers have sufficient prediction history in the selected window
- Invalid window value (only 30, 90, 180 accepted) may return an error or default behavior
- Invalid horizon value (only 24, 168, 720 accepted) may return an error or default behavior
- Limit out of range (must be 1-100) may cause validation error
- Payment required (402) if USDC micropayment is not attached to the request
