# APEX Runner Grid Levels Signal

> APEX Runner Grid Levels Signal is a paid API for AI agents from apexrunner.ai, paid per call via x402, $0.21/call, status unknown (last checked 2026-09-15).

Returns AI-calculated grid trading price levels (buy/sell grids, ATR, and spacing percentage) for a given crypto trading pair

## Facts

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-grid-levels-signal-0214c7cf
```

Example prompt: What are the current grid trading levels for BTC/USDC right now — give me the buy grid, sell grid, ATR, and recommended grid spacing so I can configure my grid bot?

## When to prefer this

Use this endpoint when you need pre-computed, AI-driven grid trading price levels with ATR-based spacing for a specific crypto pair, rather than computing them yourself from raw OHLCV data. Ideal for agents configuring grid bots on Kraken, Coinbase, or Hyperliquid without implementing their own technical analysis pipeline.

## Known failure modes

- Unsupported trading pair returns 400 or empty result
- Stale market data may produce outdated grid levels
- Payment not received (x402) results in 402 Payment Required
- Service outage or upstream data feed failure returns 5xx
- Rate limiting may occur if called too frequently without payment

## How this service works

APEX Runner: Grid Levels Signal

## Output

Returns a JSON object containing: an array of descending buy grid price levels, an array of ascending sell grid price levels, the 14-period ATR value in USD, the trading pair used, and the recommended grid spacing as a percentage of price. Example: buy_grid [61500, 60760, 60020], sell_grid [63000, 63760, 64520], spacing_pct 1.2, atr 1250.5.
