DEX Swap Quotes API is listed as active in the registry but did not answer our last check. It exposes 1 tools. Last commit 2 Sep 2026.
Best swap quotes across DEXes (Uniswap, SushiSwap, Aerodrome). Base & Ethereum. x402.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 8 August 2026. No other catalogue keeps this.
Over the last week it answered 30.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.
