AxLabs has deployed the complete Ax402 stack on Neo X, giving developers a live payment infrastructure to monetize REST APIs, gate resources behind a stablecoin paywall, and let AI agents pay each other programmatically. Payments settle on a per-request basis using supported tokens including $USDC and xGAS.
The release of the Ax402 stack marks its move from the initial July launch, covered by NNT, to a full production deployment. Ax402 is built on x402, an open protocol that repurposes the HTTP 402 Payment Required status code as the trigger for machine-to-machine payments. When Ax402 first launched on Neo X in July, the gateway integrated through xGAS, a wrapped GAS token deployed by Bane Labs for x402 payments, providing a Neo-native settlement option alongside the protocol’s broader $USDC support.
$USDC settlement on Neo X became possible one day before this announcement, when $USDC.e and WETH arrived on the network through Chainlink’s CCIP-powered Transporter bridge on Sept. 14.
What it enables #
Ax402 addresses a friction point in machine-to-machine commerce: AI agents and API consumers currently lack a standard way to pay for resources on a per-request basis without accounts, subscriptions, or checkout flows.
For example, a research agent could pay for a single query to a premium data API, a coding agent could pay to run a specialized security scan, or one AI agent could pay another for a translation or target="_blank" rel="noopener">ax402.io.
