# BTC15 Threshold Pressure Alert

> BTC15 Threshold Pressure Alert is a paid API for AI agents from xx402.icu, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a pressure alert indicating whether Bitcoin's current 15-minute prediction market price is within a user-defined USD gap of a target threshold, along with derived pressure scores and liquidity signals.

## 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`):

```sh
zero fetch --capability btc15-threshold-pressure-alert-e2b4c0d7
```

Example prompt: Check the current BTC 15-minute prediction market for threshold pressure — alert me if Bitcoin is within $75 of the target and the pressure score is at least 30, looking back over the last 90 snapshots.

## When to prefer this

Use this endpoint when you need a single, pre-computed pressure alert for Bitcoin's 15-minute prediction market based on configurable threshold proximity and minimum pressure score. It is purpose-built for BTC microstructure monitoring and does not require the caller to aggregate raw tape data. Prefer it over generic price feeds when you want a boolean alert_active flag plus supporting liquidity and pressure signals in one response.

## 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 range returns validation error
- invalid or non-existent market_timestamp returns error or empty result
- live collector database unavailable causes source_status degradation
- payment failure (x402) causes 402 response before data is returned
