FluxA
FluxA is a company building payment infrastructure for AI agents. Its own site describes a wallet an agent spends from within a budget its user approves, single-use virtual cards, a marketplace of paid services, and a product for accepting USDC payments from agents.
The site's central idea is that a user signs one payment intent, a budget and a purpose, and the wallet then signs each spend that stays inside it, with a risk engine checking every payment against the intent. It names support for x402 among the ways an agent can pay and be paid. The entry on an agent wallet defines the general thing.
FluxA also publishes a protocol of its own for embedding a payment mandate inside a call, with settlement deferred and batched on chain. Its site describes that protocol as usable within x402 calls.
→ FluxA is named in this issue of the Machine Commerce Reality Index, where probe402 reports what public settlement registers published for each facilitator.
