## 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 genesis-token-labs-live-crypto-token-spot-price-f1baca6f
```

Example prompt: What's the current USD spot price of ETH right now? I need the live aggregated price for my portfolio calculation.

## When to prefer this

Choose this endpoint when you need a real-time, aggregated USD spot price for a crypto token and want pay-per-call pricing at $0.001 per request with no subscription required. It supports both ticker symbol lookups (e.g. ETH) and contract address + chain lookups, making it flexible for both well-known and long-tail tokens. Prefer it over centralized exchange APIs when you need aggregated pricing across sources rather than a single exchange's order book price.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty data
- Invalid contract address format returns a 400 bad request
- Chain parameter not supported for address-based lookup
- Service unavailable or price feed outage results in non-200 response
- Rate limiting or payment failure (402) if USDC payment is not properly attached

## How this service works

Use when an agent needs a live crypto token spot price in USD for trading, pricing, or portfolio math, for $0.001 per call. Example input: GET /x402/v1/token-price?symbol=ETH (or ?address=0x…&chain=base). Example output: {"symbol":"ETH","priceUsd":3412.55,"source":"aggregated","ts":"2026-10-30T14:00:00Z"}

## Output

Returns a JSON object with the token symbol, current USD price (as a float), the aggregation source label, and an ISO 8601 timestamp of when the price was recorded. Example: {"symbol":"ETH","priceUsd":3412.55,"source":"aggregated","ts":"2026-10-30T14:00:00Z"}.
