The same buy, request by request

The shapes differ in one way that matters to a bot: GMGN returns a route to sign, BLIX returns a quote with the transaction, so the fee, the fill and the priority fee can be checked in code before anything is signed.

// Node 20+. The GMGN shape is the one its docs describe (a route, then a proxy send); check them for the current parameters.
const sol = "So11111111111111111111111111111111111111112";

// GMGN: ask for a swap route (the transaction comes back built), then send the signed bytes through GMGN's proxy
const route = await fetch(`https://gmgn.ai/defi/router/v1/sol/tx/get_swap_route?token_in_address=${sol}&token_out_address=${MINT}&in_amount=100000000&from_address=${WALLET}&slippage=3`).then((r) => r.json());
// … sign route.data.raw_tx.swapTransaction with your key, then POST it to https://gmgn.ai/txproxy/v1/send_transaction

// BLIX: the build carries the quote; sign it and hand it back to send (staked path, re-sent until it lands)
const H = { authorization: `Bearer ${process.env.BLIX_KEY}`, "content-type": "application/json" };
const built = await fetch("https://blixvip.com/api/v1/trade/build", { method: "POST", headers: H, body: JSON.stringify({ wallet: WALLET, mint: MINT, side: "buy", sol: 0.1, slippageBps: 300 }) }).then((r) => r.json());
if (built.quote.feeSol > 0.003) throw new Error("fee higher than expected");   // the quote is there to be checked
// … sign built.transaction, then POST { transaction } to https://blixvip.com/api/v1/trade/send

What changes when a GMGN bot moves

• No key upload, no whitelist. There is nothing to register but an account; the key is made on the page and sent as a bearer header from anywhere.
• Solana only. A BSC or Base leg stays on GMGN (or Jupiter has nothing for it either); BLIX trades pump.fun's curve and PumpSwap today.
• The data side maps cleanly. GMGN's token, wallet and K-line calls have counterparts in /api/token, /api/wallet-page and /api/candles on the same key, and the GMGN API page walks through them.

The trade API itself is documented once: the four calls, the flow in curl, what a trade costs, the rules, limits and what is live and what is next.
