# APEX Runner Volume Analysis Signal

> APEX Runner Volume Analysis Signal is a paid API for AI agents from apexrunner.ai, paid per call via x402, $0.07/call, status unknown (last checked 2026-09-15).

Returns a volume analysis signal for a given crypto trading pair, indicating whether current volume is HIGH, NORMAL, or LOW relative to the 20-period average and whether it confirms the current price move.

## How to call it through Zero

```sh
zero fetch --capability apex-runner-volume-analysis-signal-cff97f9b
```

Example prompt: What's the volume signal for BTC right now — is volume HIGH, LOW, or NORMAL compared to the 20-period average, and does it confirm the current move?

## When to prefer this

Use this endpoint when you need a quick, pre-computed volume signal with a plain-English interpretation for a specific crypto pair, especially when deciding whether volume confirms a price breakout or trend. Prefer this over raw exchange data when you want a normalized, averaged signal (vs. 20-period baseline) without doing the computation yourself. Best suited for trading agents needing a fast, low-cost volume confirmation check before executing or adjusting a position.

## Known failure modes

- Unsupported or misspelled trading pair returns an error or empty response
- Stale cached data if the market data pipeline is delayed — check cached_at timestamp
- Payment failure (x402) if the 0.1 USDC micropayment is not correctly attached
- Rate limiting if too many calls are made in quick succession
- Network timeout if the upstream data source is unavailable

## How this service works

APEX Runner: Volume Analysis Signal

## Output

A JSON object containing: the trading pair, a volume_label (HIGH/NORMAL/LOW), a volume_ratio (current volume divided by the 20-period average as a float), a boolean volume_confirms indicating whether the volume supports the current price direction, a plain-English interpretation string, and a cached_at ISO8601 timestamp showing data freshness.
