## 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 liminal-spot-prices-bulk-e77d6cfe -d '<json body>'
```

Example prompt: What are the current spot prices for Bitcoin, Ethereum, and Solana in USD — I need a live snapshot right now?

## When to prefer this

Choose this endpoint when you need live spot prices for multiple crypto assets or fiat pairs in a single low-latency call and are comfortable with x402 micropayment authentication ($0.01 USDC per call). It is ideal for agents that need real-time price data without a subscription, paying only per use. Prefer alternatives if you need historical price data, order book depth, or OHLCV candlestick data.

## Known failure modes

- HTTP 402 returned if no payment signature is provided — must retry with PAYMENT-SIGNATURE header
- Individual asset lookups within the bulk response may return ok:false with an error string if the data source is unavailable
- Invalid or unsupported asset symbols return an error entry in the results array rather than rejecting the whole request
- Network timeout if Cloudflare Worker is under high load

## How this service works

Live crypto spot-price snapshots (USD) and fiat FX spot rates. Pay-per-request via x402 v2: $0.01 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453), Monad (eip155:143), Arbitrum (eip155:42161), Optimism (eip155:10), Polygon (eip155:137), Avalanche (eip155:43114) or Solana, scheme exact (EIP-3009). Unpaid calls return HTTP 402 with a base64 PAYMENT-REQUIRED header; retry with a PAYMENT-SIGNATURE header.

## Output

A JSON object containing a Unix timestamp (as_of), an array of per-asset results each with ok status and either price data or an error message, the service name ('bulk'), the USDC price charged, and counts of ops requested vs succeeded.
