# APEX Runner Composite Signal

> APEX Runner Composite Signal is a paid API for AI agents from apexrunner.ai, paid per call via x402, $0.7/call, status unknown (last checked 2026-09-15).

Returns an AI-aggregated directional bias score (bullish/bearish/neutral) and per-component sub-scores for crypto market conditions

## Facts

- Endpoint: GET https://apexrunner.ai/signals/apex-composite
- Price: $0.7/call
- Payment: x402
- Status: unknown

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-composite-signal-f03c03e1
```

Example prompt: What is the current APEX composite signal for crypto — is the market bullish, bearish, or neutral right now, and what are the component scores for momentum, volume, regime, and fear/greed?

## When to prefer this

Use this endpoint when you need a single, pre-aggregated directional market signal across multiple crypto signal types (regime, momentum, volume, sentiment) and don't want to build your own aggregation logic. Prefer this over raw exchange data or single-indicator feeds when you want a holistic, graded market stance with a human-readable conviction score.

## Known failure modes

- Payment not completed — returns 402 if the $1 USDC micropayment via x402 is not attached
- Stale data — signal may reflect recent but not real-time market conditions
- Upstream data unavailable — component scores may be missing if data providers are down
- Rate limiting — excessive calls may be throttled

## How this service works

APEX Runner: Apex Composite Signal

## Output

A JSON object containing: a directional bias string (bullish, bearish, or neutral), a letter grade A–F summarising overall signal quality, an integer composite score 0–100 (higher = stronger bullish conviction), and a components object with individual 0–100 scores for fear_greed, momentum, volume, and regime sub-signals.
