SwapTitan Swap API — free, non-custodial, no API key

以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →

Swap on **Solana** and **7 EVM chains** with one free REST API. Every endpoint returns an **unsigned transaction** — you sign with your own wallet. The server never holds funds, never sees keys. No registration, no API key, no KYC.
Base URL: https://swaptitan.net
Run as MCP server (stdio)
A self-contained MCP server — no dependencies, Node >= 18:
18 tools (prices, quotes, Solana + EVM swaps, routing, priority fees, Hyperliquid, rug checks). The protocol layer runs locally; tool calls hit the free public API. Hosted alternative: https://swaptitan.net/mcp (streamable HTTP, no auth).
Solana swap (Jupiter aggregator)
Response contains swapTransaction (base64, unsigned) — deserialize, sign, send to any RPC:
- from / to: sol, usdc, usdt or any base58 mint (memecoins, pump.fun tokens — anything Jupiter routes)
- amount (human units for sol/usdc/usdt) or amountRaw (base units, any mint)
- slippageBps: 1–1000, default 50
- Pricing: **free API** — 0.3% routing fee + small flat network service fee inside the transaction (disclosed in the response as feeBps and serviceFeeLamports)
EVM swap — Ethereum, Base, BSC, Arbitrum, Polygon, Optimism, Avalanche (KyberSwap aggregator)
Response: tx: { to, data, value } — sign and broadcast with your own wallet (ethers/viem/web3.js). ERC-20 input requires prior approval to tx.to. Pricing: free API, 0.3% routing fee in calldata.
Universal cross-chain router
One call compares **all rails** (cross-chain exchange bridge, direct H2H liquidity, Solana DEX) and returns the best route with ready-to-execute parameters — including hard pairs like eth -> xmr:
Solana priority-fee oracle
Live compute-unit price tiers, refreshed continuously — call before sending any Solana transaction:
Connect
Remote endpoint (no auth, free tier): https://swaptitan.net/mcp — JSON-RPC 2.0, streamable HTTP, 18 tools.
- **Claude (web & desktop):** Settings → Connectors → *Add custom connector* → paste https://swaptitan.net/mcp → Connect.
- **Claude Desktop / Cursor / VS Code / Cline:** add to your MCP config:
- **Local stdio** (no hosted dependency): node mcp-server.js (see above).
- **Any SDK / agent:** call tools/list then tools/call. Tools: sol_swap, evm_swap, smart_route, sol_priority_fee, swap_create, swap_status, get_prices, rug_check and more.
