# APEX Runner: Crowded Trade Detector Signal

> APEX Runner: Crowded Trade Detector Signal is a paid API for AI agents from apexrunner.ai, paid per call via x402, $0.007/call, status unknown (last checked 2026-09-14).

Detects crowded crypto trades by analyzing wallet consensus, scoring crowding severity, and surfacing contrarian opportunities and uncrowded alternatives.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 apex-runner-crowded-trade-detector-signal-40f6f1c3
```

Example prompt: Check APEX Runner's crowded trade detector right now and tell me which crypto coins are dangerously overcrowded, their crowding severity and direction, any contrarian signals I should consider, and what uncrowded opportunities look worth exploring.

## When to prefer this

Use this endpoint when you need real-time, wallet-consensus-backed detection of overcrowded crypto trades and want both risk warnings for crowded positions and actionable contrarian or uncrowded alternatives. Prefer it over generic sentiment APIs when you specifically need crowding scores per coin, severity/direction breakdowns, and signals grounded in live wallet data rather than social media or order book analysis.

## Known failure modes

- No query parameters required so malformed requests are unlikely; payment failure (402) if $7 USDC not provided via x402 protocol
- Service unavailable if live trading infrastructure is offline
- Stale signal if valid_for_seconds has elapsed since last generation
- Empty crowded_trades array if no significant crowding is detected in the current market
- Rate limiting or access denial if called too frequently

## How this service works

APEX Runner: Crowded Trade Detector Signal

## Output

Returns a list of crowded crypto trades with per-coin crowding scores, severity ratings (e.g. high/medium/low), direction (long/short), risk warnings, contrarian signals and their strength, plus a market consensus summary, consensus risk level, number of wallets sampled, uncrowded opportunity tickers, signal metadata (hash, version, instance, verify URL, evolution runs, live capital deployed flag), and a validity window in seconds.
