x402 protocol support

まず、依存関係 zyte_api[x402] と https://api-x402.zyte.com を選択するソースのエントリポイントを確認し、認証動作を https://api.zyte.com と比較します。x402 がサポートされているか、表示されている認証が想定されたものか、どの設定またはドキュメントが必要かを明らかにできれば完了です。

Hi,

Could you please clarify whether the Zyte API currently supports the x402 protocol?

I contacted support previously, but I didn't receive a clear answer about whether this functionality is currently available.

I tried sending the following request:

from zyte_api import ZyteAPI

client = ZyteAPI(eth_key="my eth private key in base network")

result = client.get({"url": "https://toscrape.com", "httpResponseBody": True})
print(result)

However, I receive the following error:

zyte_api._errors.RequestError: RequestError: 401, message=Unauthorized, headers=<CIMultiDictProxy('Date': 'Sun, 19 Jul 2026 15:12:04 GMT', 'Content-Type': 'application/problem+json', 'Content-Length': '202', 'Connection': 'close', 'WWW-Authenticate': 'Basic realm="Zyte API"', 'Request-Id': '01be2ad971ff6e6511893c4a810d49a6', 'Vary': 'Accept-Encoding', 'Strict-Transport-Security': 'max-age=31536000; includeSubDomains; preload', 'Access-Control-Allow-Credentials': 'true', 'Access-Control-Expose-Headers': '*, X-Project-Key', 'Access-Control-Allow-Methods': 'GET, PUT, POST, DELETE, PATCH, OPTIONS', 'Access-Control-Allow-Headers': 'DNT, Keep-Alive, User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Type, Range, Authorization, X-Project-Key', 'Access-Control-Max-Age': '1728000')>, body=b'{"type":"/auth/not-valid","title":"Authentication Info Invalid","status":401,"detail":"No valid authentication info found in the request.

Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x101776c90>

These are my project dependencies:

requires-python = ">=3.12"
dependencies = [
    "zyte-api[x402]>=0.10.0",
]

While looking through the project source code, I found the endpoint https://api-x402.zyte.com. However, when I send requests to this endpoint, it also requires authentication in the same way as the main endpoint (api.zyte.com).

Is this the expected behavior, or is x402 support currently unavailable?
