## When to prefer this

Use this endpoint when an autonomous agent needs a curated, risk-tiered tape of recent Bitcoin 15-minute Up/Down prediction markets with pre-computed buy/avoid signals and buyer playbooks, rather than raw exchange data or general crypto price feeds. Best suited for agents making micro-decisions on prediction market participation with a $0.01 USDC per call budget.

## Known failure modes

- limit exceeds maximum of 24 — validation error
