Side by side
| Jupiter Swap API | BLIX trade API | |
|---|---|---|
| Covers | Every DEX and launchpad Jupiter indexes, any token pair | pump.fun bonding curve and PumpSwap pools (SOL pairs) today |
| Round trips before signing | Two (quote, then swap transaction) | One account read; the build is local |
| Fee | None from Jupiter; integrators may add a platform fee | 2% a trade, 1.6% with an invite, inside the transaction |
| Auth and limits | Keyless on the free endpoint, metered; a portal key raises the limits (per Jupiter's plans) | Bearer key; 120 quotes and builds, 60 sends a minute |
| Who signs | You | You |
| Sends | You, to your own RPC | Blix: Helius Sender staked path + RPCs, re-sent every second, landing reported; or send it yourself |
| Stream | None (price API) | WebSocket, PumpPortal-compatible: launches, trades, migrations |
| Data on the same key | Prices, token lists | Pulse, holders with snipers and bundles, candles from real trades, AI grades, smart-money wallets (61 endpoints) |

The same buy, request by request
# The same buy, 0.1 SOL of one coin, asked of each. Both return something you sign yourself.
SOL=So11111111111111111111111111111111111111112
# Jupiter: a quote, then the swap transaction for that quote (two round trips; keyless on the free endpoint)
curl -s "https://lite-api.jup.ag/swap/v1/quote?inputMint=$SOL&outputMint=$MINT&amount=100000000&slippageBps=300" > quote.json
curl -s https://lite-api.jup.ag/swap/v1/swap -H "content-type: application/json" \
-d "{\"quoteResponse\":$(cat quote.json),\"userPublicKey\":\"$WALLET\"}"
# → { "swapTransaction": "<base64>", ... } sign it, send it to your own RPC, poll the signature yourself
# BLIX: the build is the quote and the transaction in one answer (one account read, no router)
curl -s https://blixvip.com/api/v1/trade/build -H "authorization: Bearer $BLIX_KEY" -H "content-type: application/json" \
-d '{"wallet":"'$WALLET'","mint":"'$MINT'","side":"buy","sol":0.1,"slippageBps":300}'
# → { "transaction": "<base64>", "quote": {...}, "validForMs": 90000 } sign it, POST { transaction } to /api/v1/trade/send
# → { "signature": "…", "status": "confirmed", "slot": …, "landedMs": 1180 }Which one, when
- A coin in its first minutes on pump.fun, where every hundred milliseconds matters: BLIX. The transaction is built from one read of the curve and sent over staked connections with your priority fee and tip; the quote shows the exact fill.
- A coin on Raydium, Meteora, Orca, or a pair that is not against SOL: Jupiter today; BLIX answers
409 route: "unsupported"for those until its Jupiter-routed build with Blix's fee ships. - A bot that needs the filter as much as the fill: BLIX, because the holder ledger, the AI grade and the live stream are on the same key as the build; with Jupiter you assemble those from other services.
- Zero fee above the pool's own: Jupiter, and you run your own RPC and sends.
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.

Frequently asked questions
Is Jupiter's trading API free?
Yes to callers; Jupiter earns from its own products and lets integrators attach a fee. BLIX's API charges 2% a trade (1.6% with an invite) and bundles the staked send path, the stream and the data.
Why would I pay BLIX when Jupiter is free?
For pump.fun's first minutes: one account read and a local build instead of two router round trips, staked sends with the landing time reported, and the holder ledger and AI grade on the same key to decide with. For anything else, use Jupiter; BLIX will route those through Jupiter itself next.
Will BLIX use Jupiter?
Yes, for every launchpad and pool it does not hand-build, with Blix's fee attached, in the next phase. Hand-built paths stay where milliseconds are worth money.
