## When to prefer this

Choose this endpoint when you need a real-time on-chain swap quote specifically for tokens on Robinhood Chain using the Pons v2 / Uniswap infrastructure, especially when you need hook-decoded pool state or are working with Pons launchpad-graduated tokens. Prefer over generic DEX aggregators when Robinhood Chain coverage is required.

## Known failure modes

- Invalid or unsupported token address returns an error or empty result
- Token pair with no liquidity pool returns no quote
- Malformed query parameters result in upstream API error
- Network issues on Robinhood Chain cause timeout or unavailable response
- Payment failure (insufficient USDC/USDG balance) blocks the request
