## 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-prices-crypto-spot-price-72e1f898
```

Example prompt: What's the current spot price of Bitcoin in USDT right now? Pull it from Agent Prices using my USDC balance — no API key needed.

## When to prefer this

Choose this endpoint when you need a lightweight, keyless, pay-per-call real-time crypto spot price lookup — especially useful for AI agents that cannot manage long-lived API credentials and need to pay micro-amounts via USDC x402. Best for single-pair spot price queries where Binance pricing is acceptable and low latency matters.

## Known failure modes

- Invalid or unsupported trading pair symbol returns an error or empty result
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting or quota exceeded on underlying Binance Vision feed
- Network timeout from Cloudflare Worker if Binance data source is unavailable
- Missing or malformed query parameters returns a validation error

## How this service works

## Output

A JSON object containing the symbol (e.g. 'BTCUSDT') and the current spot price as a number (e.g. {"symbol": "BTCUSDT", "price": 78000}), sourced in real time from Binance Vision public market data.
