## When to prefer this

Use this endpoint when you need a quick, reliable USD spot price for any ERC-20 token by contract address across major EVM networks (Ethereum, Base, Polygon, Arbitrum, Optimism), especially when building portfolio valuation tools or fiat-denominated balance displays backed by Alchemy's aggregated feed.

## Known failure modes

- Invalid or unrecognized contract address returns an error or null price
- Unsupported network name causes a validation error
- Token not listed on Alchemy's price feed returns no price data
- Malformed 0x address format causes a bad request error
- Payment failure (x402 protocol) prevents the request from being processed

## Output
