Summary of the week in AiFi

Amid all the green this week, Coinbase also introduced us to a new acronym for the growing world of agent payments: AiFi.

While I am still against another cutesy term, AiFi, short for finance agentseems to be the most appropriate term to encompass x402, MPP, agent trading, agent trading – anything that emerges as agents gain access to ready-made money.

Here’s to making it stick. Luckily, we received more than just well wishes this week.

The first major development was Stripe’s deal to acquire OpenRouter, which I wrote about on Monday, arguing that Stripe was moving into the inference routing business, a business ripe for the stablecoin and HTTP 402-based infrastructure it has spent the last year building.

Inference is by and large the (current) use case for x402 and agent payments, and Stripe clearly knows this. Two days after my article, a leaked investor note satisfactorily validated this thesis: Stripe described capital and intelligence (interchangeable with inference) as “two digital streams” increasingly supports businesses and said stablecoins will likely become the “native currency of the AI ​​economy.»

OpenRouter gives Stripe a place in this intelligence pipeline. And even if routing markets remain young and susceptible to manipulation, as Tarun and his co-authors demonstrated this week, the arrival of a payments company whose mission is to make economic flows more efficient offers some hope that Stripe can help mature the market.

But OpenRouter was just one of three headline developments this week for AiFi: the second was AWS making AgentCore Payments generally available on Tuesday.

AgentCore offers developers a layer of control to equip our mechanical servants with authorized access to capital. Users can connect wallets, set spending limits, and audit activities, while AgentCore handles the plumbing necessary for agents to access paid services via x402 and MPP.

AWS is by no means alone in building control layers.

I wrote about Catena, Ampersendand others before. Additionally, Ramp added support for x402 this week alongside similar monitoring features, building on its tightly controlled agent cards and financial tools for enterprise agents. The distinction is mostly in the audience: AgentCore feels like a customizable development framework, while Ramp feels like the enterprise financial version, connecting agents to company budgets, payment methods, and controls.

Ramp adds x402 payments for AI agents on Bankless

Ramp adds x402 payments for AI agents, expanding its agent funding campaign as AWS and Stripe accelerate the agent payments race.

Both converge on the same primitive: give money to an agent, define exactly what he can do with it, and keep track of what happens.

But overall, the significance of this launch is that Amazon is now firmly involved in AiFiand more particularly in x402. As you may recall, they join Google Cloud, which previously partnered with the Solana Foundation on Pay.sh, which allows agents to access proprietary Google Cloud APIs through x402.

The third major development came from one of China’s payments giantsAlipay, which launched its new full-stack agent commerce platform last Tuesday. Among the offerings the platform gives merchants access to is an agent payments stack that supports payments via the x402 protocol.

Quite big.

A More Something to watch out for

Beyond these three major announcements, an earlier development from this week is worth keeping an eye on.

The first is Rain Agent Payments Alliancewhich brings together companies such as Visa, Mastercard, Circle, among others, to work on identity, authorization, standards and regulation of agent commerce.

There is no tangible product yet, but Rain sits at an interesting crossroads between on-chain money and existing card rails. If x402 and MPP continue to develop the native side of machine payments while cards remain the easiest way to reach most merchants, Rain is well-positioned to help bridge the two.

Overall, it was a historic week on all fronts.

Depreciation trading returned as markets reacted to interventionist monetary policy, the type of environment Bitcoin was built in response to. The US government has indicated that it is working to introduce new financial instruments (expandable perpetuals) through decentralized means (by introducing Hyperliquid domestically). And AiFi has released another ‘before and after’ week, seeing crypto integrated by some of the world’s biggest technology and payments companies to enable machine-ready money.

I can’t wait to see what next week has in store for me.
