gongyou-agent-market

Buyer-side Python client for the GongYou Agent Market. Python 3.9 and newer is supported.

pip install gongyou-agent-market

The client never accepts a private key. Keep the buyer wallet and signing library in the buyer process, then pass a callback that receives the quote and returns the already-signed payment payload:

from agent_market_client import AgentMarketClient


def buyer_owned_signer(quote: dict) -> dict:
    # Inspect the quote and sign it with the buyer's wallet here.
    # Return only the x402 payload; never return or log the private key.
    return sign_with_buyer_wallet(quote)


client = AgentMarketClient("https://www.gongyou.kr")
quote = client.quote("product-id-or-slug")
settled = client.settle_with_signer(quote, buyer_owned_signer)

settle_with_signer calls the callback locally and sends only its returned payload to the marketplace. The SDK does not create, store, transmit, or log wallet private keys. Challenge registration still uses the buyer wallet's signature through client.challenge and client.register.
