Paladin Swap
A multi-aggregator swap router that queries 0x and Velora in parallel on Base and returns whichever delivers the higher post-fee buy amount. Exposes three MCP tools: swap_quote returns ready-to-execute calldata with slippage protection and a 10 bps affiliate fee already baked in, trust_check_preview runs a sample-fixture risk screen against OFAC/Goplus/Etherscan (the real paid endpoint costs $0.001 USDC per call via x402), and swap_health reports service liveness and per-source counters. Non-custodial, meaning your agent signs and submits every transaction. Reach for this when you need an agent to execute swaps without writing aggregator glue or slippage logic yourself.

Readme
paladin-swap-mcp
Open client and API spec for PaladinFi Swap — a competitive multi-aggregator swap router for AI agents on Base. This repository contains the public REST and MCP API specification, working code examples, and thin client wrappers. The hosted backend at swap.paladinfi.com is proprietary.
Routing scope. PaladinFi Swap queries integrated upstream aggregators (currently 0x and Velora) in parallel and returns whichever delivers the higher post-fee buy amount. We do not represent any returned route as the best available, lowest-cost, or optimal across the broader DeFi market. Phrases like "best execution" are reserved-meaning terms in U.S. securities law and are deliberately not used here.
