## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Choose this endpoint when an autonomous agent or risk tool needs a derived, actionable alert about Bitcoin 15-minute prediction-market threshold proximity — rather than raw price data or generic market feeds. It is specifically designed for x402-paying agents that need a structured buyer playbook, pressure scoring, and priority queues to decide whether to enter or avoid a btc15 up/down position. Prefer it over general crypto price APIs when the agent needs pre-computed risk signals and decision evidence for short-term BTC prediction markets.

## Known failure modes

- lookback_rows outside 15–180 range returns validation error
- threshold_gap_usd outside 5–250 range returns validation error
- pressure_score_min outside 0–100 returns validation error
- invalid or non-existent market_timestamp returns market-not-found error
- payment not processed (402) if x402 micropayment fails
- live collector database unavailable causes stale or empty source_status
- no active market returns null or empty market field
