jupiter-swap-python 0.1.0

Async Python client for the Jupiter DEX aggregator on Solana — V6 quote/swap and Ultra API.

jupiter-swap-python

The missing Jupiter swap client for Python. Async. Typed. Production-tested.

Jupiter's own Python SDK was abandoned (returns 404). This library fills the gap — a clean, typed, async client for Jupiter, the #1 DEX aggregator on Solana.

⚡ Quickstart

pip install jupiter-swap-python

Get a quote

import asyncio
from jupiter_swap import JupiterClient

SOL = "So11111111111111111111111111111111111111112"
USDC = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"

async def main():
    async with JupiterClient() as jup:
        quote = await jup.get_quote(SOL, USDC, 1_000_000_000)  # 1 SOL
        print(f"1 SOL = {int(quote.out_amount) / 1e6:.2f} USDC")
        print(f"Price impact: {quote.price_impact_pct}%")

asyncio.run(main())

Swap tokens

async with JupiterClient(api_key="your-key") as jup:
    # Step 1: Get quote
    quote = await jup.get_quote(SOL, USDC, 1_000_000_000)

    # Step 2: Build swap transaction
    swap = await jup.get_swap_transaction(
        quote,
        user_public_key="YourWalletPublicKey...",
        priority_fee_lamports=500_000,  # 0.0005 SOL
    )

    # Step 3: Sign and send swap.swap_transaction with your wallet
    print(f"Transaction ready (block height: {swap.last_valid_block_height})")

Ultra API (recommended for production)

async with JupiterClient(api_key="your-key") as jup:
    # Combined quote + swap in one call
    order = await jup.ultra_order(
        input_mint=SOL,
        output_mint=USDC,
        amount=1_000_000_000,
        taker="YourWalletPublicKey...",
    )

    print(f"Swap type: {order.swap_type}")
    print(f"Out amount: {order.out_amount}")

    # Sign order.swap_transaction with your wallet, then:
    tx_sig = await jup.ultra_execute(signed_transaction, order.request_id)
    print(f"Executed: {tx_sig}")

Token verification

from jupiter_swap import TokenClient

async with TokenClient() as tokens:
    info = await tokens.get_token_info("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v")
    print(f"{info.symbol} — verified: {info.is_verified}, banned: {info.is_banned}")

    # Check if a token is a known scam
    if await tokens.is_banned("SomeScamMint..."):
        print("🚫 Token is banned!")

🔧 API Reference

JupiterClient

Method	Description
get_quote()	Get the best swap route and price
get_swap_transaction()	Build a signable transaction from a quote
ultra_order()	Combined quote + swap via Ultra API (MEV protection)
ultra_execute()	Execute a signed Ultra swap order

TokenClient

Method	Description
get_token_info()	Get token metadata and verification status
is_banned()	Check if a token is on the banned list
is_verified()	Check if a token is verified
get_strict_list()	Get all strictly verified tokens
refresh_banned_list()	Manually refresh the banned list

Models

• QuoteResponse — Route details, expected output, price impact
• SwapResponse — Base64 transaction ready to sign
• UltraOrder — Combined quote + transaction from Ultra API
• TokenInfo — Name, symbol, decimals, verification flags

🛡️ Why this library?

Problem	Solution
Jupiter's Python SDK is deleted	This exists
Raw httpx.post() calls everywhere	Typed client with proper models
No 429 handling	Built-in retry with exponential backoff
Token safety is an afterthought	TokenClient with banned/verified checks
Sync-only clients	Fully async with httpx

🔑 API Key

A Jupiter API key is optional but recommended for production use (higher rate limits).

Get one at station.jup.ag.

client = JupiterClient(api_key="your-api-key")
