## 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 crypto-price-data-agent-tollgate-engine-49ca0780
```

Example prompt: What are the current prices for BTC, ETH, and SOL quoted in USDT, including their 24h highs, lows, and percent changes?

## When to prefer this

Choose this endpoint when you need real-time spot prices and 24h statistics for one or more crypto assets in a single call, especially within an x402 micropayment-enabled agent workflow. It supports batching up to 20 symbols, making it efficient for portfolio checks or multi-asset dashboards. Prefer this over general-purpose market data APIs when you're already operating in an x402/USDC payment context and need low-cost, per-call pricing at $0.001 USDC.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty prices array
- Exceeding 20 symbols in a single request may result in an error
- Missing required 'symbols' query parameter returns a validation error
- Payment failure via x402 (insufficient USDC balance or unsupported chain) blocks the request
- Network timeout or upstream exchange outage results in a 5xx error

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

Returns a JSON array of price objects, one per requested symbol. Each object includes the trading pair symbol (e.g. BTCUSDT), current spot price, 24h high, 24h low, 24h percent change, and 24h quote volume. Up to 20 symbols can be queried per call.
