## 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 no-hands-ai-eth-usd-live-price-quote-1ce8474d
```

Example prompt: What's the current live ETH to USD price for 2.5 ETH, with source attribution so I can verify the quote?

## When to prefer this

Choose this endpoint when your agent needs a real-time, source-attributed ETH/USD price quote with explicit freshness metadata and market status — particularly for autonomous budget checks, spending limit enforcement, or onchain payment authorization where auditability of the price source matters. Prefer over generic market APIs when you need structured freshness signals and fallback transparency in the response.

## Known failure modes

- Invalid or non-positive amount parameter returns a validation error
- Stale or unavailable market data may trigger fallback_used=true with fallback_reason populated
- Upstream price provider outage could cause request failure or degraded freshness
- Payment requirement not met (HTTP 402) if x402 payment header is absent or incorrect
- Network timeout to Cloudflare Worker edge node

## How this service works

Return a source-backed live ETH to USD quote for autonomous-agent budget checks.

## Output

Returns a structured JSON object containing the ETH/USD unit price, the converted USD value for the requested ETH amount, market status, freshness metadata (source observation timestamp, response generation time, freshness in seconds), the list of contributing data sources with per-leg details, and provider/schema versioning fields. Includes a result_id for traceability and a fallback_used flag indicating whether a backup price source was used.
