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 agent-signals-crypto-price-feed-cryptojp-com-v1-price-e78a2f67
```

Example prompt: What's BTC's current price right now, including the 24h high and low, how it's changed today, and how the price compares across Binance and Bybit?

## When to prefer this

Use this endpoint when an AI trading agent needs real-time cross-venue price data for a single crypto asset, including spread analysis and 24h range context. Prefer this over generic price APIs when you need multi-venue comparison (Binance + Bybit) and range-position context in a single pay-per-call call settled in USDC via x402.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Symbol not supported returns a 404 or empty result
- Payment not settled via x402 returns a 402 Payment Required
- Upstream exchange data unavailable may return stale or partial venue data
- Network timeout from exchange aggregator may cause delayed response

## How this service works

Pay-per-call crypto market-intelligence API for autonomous AI trading agents. Funding-rate, BTC lead-lag and trend/chop regime signals, settled in USDC over x402.

## Output

A JSON object containing the asset's current mid-market price, 24h high and low, 24h percentage change, 24h volume in USD, where in its 24h range the price currently sits (rangePositionPct), cross-venue spread percentage, and individual prices from Bybit and Binance.
