## 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-money-map-x402-live-token-price-pulse-7de90862
```

Example prompt: What's the current price of ETH on Base right now, including its 24-hour percent change?

## When to prefer this

Choose this endpoint when you need a lightweight, real-time single-token price lookup specifically on the Base network, paid via x402 micropayments. It is ideal for AI agents operating in the x402/agent-economy context that need a formatted, human-readable price line alongside raw USD data. Prefer it over heavier exchange APIs when you only need a quick live spot price with 24h change and already support x402 payment flows.

## Known failure modes

- Missing or invalid x402 payment header returns 402 Payment Required
- Unsupported token symbol returns an error or falls back to ETH default
- Network outage or upstream price feed failure returns 5xx error
- Malformed query parameter returns 400 Bad Request
- Payment amount insufficient for the $0.001 USDC gate returns 402

## How this service works

x402-gated live x402/agent-economy snapshot on Base.

## Output

A JSON object containing the token's current USD price, a human-readable one-line price summary string (e.g. 'ETH $4300 (1.25% 24h) on Base.'), the 24-hour percent change, the token symbol, the network identifier (eip155:8453 for Base), and an ISO 8601 timestamp for when the price was recorded.
