Example prompt: What's the current USD price, 24-hour change, and liquidity for the Base token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?

## When to prefer this

Use this endpoint when you need quick, no-auth-required USD price data for a Base network token with liquidity and volume context from DexScreener. Prefer this over on-chain RPC calls when you want human-readable price metrics without setting up oracle integrations. Ideal for agents doing DeFi research, portfolio tracking, or trade screening on Base.

## Known failure modes

- Invalid or non-Base contract address returns an error or empty result
- Token not listed on DexScreener or has no liquidity pairs — returns no data
- Newly deployed token with no trading history may have missing price or volume fields
- DexScreener API downtime or rate limiting may cause failures
- Malformed address format causes query rejection

## How this service works

Pass a Base token contract address and get the current USD price, 24h change, liquidity, and volume from DexScreener (highest-liquidity pair auto-selected). No API key required.

## Output

Returns the current USD price of the token, its percentage price change over the last 24 hours, total liquidity in USD, and trading volume — all sourced from the highest-liquidity DexScreener pair for that contract address on Base.
