x402aff - Python

PyPI Python versions License: MIT

The x402aff kit (Python): an installable x402aff package with the one-object Affiliation facade on top. This is the implementation validated end-to-end on Base mainnet.

Install

pip install x402aff                  # from PyPI
pip install 'x402aff[cdp]'           # with the CDP discovery extra

Or from a checkout / straight from git, to track unreleased changes:

pip install ./python                 # from a clone, at the repo root
pip install '.[cdp]'                 # from inside python/, with the CDP extra
pip install 'x402aff[cdp] @ git+https://github.com/MiroShark/x402aff@main#subdirectory=python'

The cdp extra adds cdp-sdk, needed only for the CDP-index discovery path (monitor, aff.scan() / pending() / splits_payload()). Without it the request-time payTo and payout-calldata paths work fine.

Vendoring instead of installing works too - copy python/x402aff/ into your project as a subpackage; the modules import each other relatively, so nothing needs rewriting and none of the generic names (split, monitor, resolver) leak into your top-level namespace.

Use

from x402aff import Affiliation

aff = Affiliation(app_code="bc_yourcode", seller_payout="0xYourWallet")

# on your x402 route:
#   pay_to=aff.pay_to           per-request split, from the X-Builder-Code header
#   extensions=aff.extensions   declares your app code `a`

# release payouts, later (permissionless):
calls, balance = aff.release("bc_alice")

Full integration guide (money path, trust model, wiring, caveats): ../docs/INTEGRATION.md. The TypeScript port lives in ../ts/ and resolves the identical split address.
