## 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`):

## When to prefer this

Use this endpoint when you specifically need trading volume data for tokens on the Pump.fun launchpad on Solana. Prefer this over generic DEX volume endpoints when focusing on newly launched memecoins and speculative tokens native to Pump.fun, powered by Bitquery on-chain data.

## Known failure modes

- Invalid or out-of-range limit parameter
- Bitquery upstream API unavailable or rate-limited
- Payment of $0.75 USDC not completed via x402 protocol
- No data available for the specified time period
