moltydex

Official Python SDK for MoltyDEX — the x402 token aggregator for AI agents on Solana.

• Zero fees on all swaps
• Best prices via Jupiter aggregator
• Automatic x402 payment handling — your agent pays for APIs automatically
• Token swaps — swap any SPL token with one function call

Install

pip install moltydex

Quick Start

from moltydex import MoltyDEX

dex = MoltyDEX(
    api_url="https://api.moltydex.com",
    wallet_path="~/.config/solana/id.json",
)

# Get a swap quote
quote = dex.quote(
    token_in="So11111111111111111111111111111111111111112",   # SOL
    token_out="EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", # USDC
    amount_in=100_000_000,  # 0.1 SOL in lamports
)
print(f"Output: {quote['output_after_fee']} USDC")

Execute a Swap

result = dex.swap(
    token_in="So11111111111111111111111111111111111111112",
    token_out="EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
    amount_in=100_000_000,
    wait_for_confirmation=True,
)
print(f"Swap signature: {result['signature']}")

Handle x402 Payments

# When your agent gets a 402 Payment Required response:
result = dex.handle_x402_payment(payment_402_response_body)

if result['ready']:
    print("Payment ready — sufficient balance")
else:
    print(f"Swap completed: {result['swap_result']['signature']}")

One-Call Auto-Pay

result = dex.x402_auto_pay(
    payment_response_body=response_402_body,
    auto_swap=True,
)
print(result)

API Reference

Wallet Configuration

# From file
dex = MoltyDEX(wallet_path="./wallet.json")

# From secret key bytes
dex = MoltyDEX(wallet_secret_key=[1, 2, 3, ...])

# From existing Keypair
from solana.keypair import Keypair
kp = Keypair()
dex = MoltyDEX(wallet_keypair=kp)
