Plexa /v1/quote — executable swap quote: the realizable fill price at your trade size, not a mid/spot price feed. Returns price impact (bps), worst-case slippage, depth and the per-leg route across Base/Polygon/Arbitrum liquidity, from canonical on-chain quoters. Call it before a swap to see what the fill actually costs. Informational data, not financial advice.
