TradingDefiBaseDexQuotes

Use when an agent is about to swap on Base and needs the best executable price before committing funds. Flow best-execution quotes: compares Uniswap V3, PancakeSwap V3 and Aerodrome across fee tiers and returns the best venue, expected output, edge vs Uniswap baseline, block number, and an expiry window so the agent knows exactly how long the price holds.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
