30k x402 listings in the world. 5.5k live. 32 write-enabled. that's it ;( Agentic payments is one of the loudest narratives right now and the actual surface area an agent can act on is basically empty. talking to builders in sf, most are treating this as a feature, not a bug. The rail is still wide open.
30,600 x402 listings across the major directories. 5,500 actually return a valid HTTP 402. Of those: — 511 process payments — 17 store data — 15 send messages The agent economy can pay. It can barely remember or talk. Here's what works. 🧵 #x402 #AIAgents #StablecoinPayments

We are moving from hardcoded integrations to agent native API discovery. Decixa is building the world’s largest x402 API index with 20,000 APIs. Your agent finds the right API. Your stack breaks less. The internet becomes callable. npx decixa-mcp
Your AI agent can now discover APIs on its own. Decixa indexes 20,000 x402-enabled APIs — verified, classified, and ready to call. One command in Claude Code: → npx decixa-mcp Stop hardcoding endpoints. Let your agent pick the right API. #ClaudeCode #MCP #x402 #AIAgents

Dragonfly CapitalのHaseeb(クリプト最大手VCの一つ)がSFで数週間過ごして気づいたこと:AIの人 たちの方がクリプト側より強気だそうです。OpenAIのSam Altman、NvidiaのJensen Huang、イーロン・マスクも公言してる。昨今クリプト業界の内の当事者が一番慎重になってる間に、外からどんどん人が入ってきてる構図。
After a few weeks in SF, one thing stands out: AI people are more bullish on crypto than crypto people are on themselves. There's this narrative forming in crypto that AI people think crypto is a joke. It's just not true. I keep hearing this over and over from AI people who remain bullish crypto. Hell, Sama, Jensen, Elon, Zuck, the biggest names in AI have all been publicly bullish on crypto and its convergence with AI. Crypto's problem right now isn't that outsiders don't believe. It's that insiders are playing scared.

Nonagon Capital x Startale Group 🤝 @StartaleGroup @nngcap We’re doubling down on the intersection of AI Agent and blockchain. This partnership is all about making "Agentic Payments" a reality enabling AI agents to pay, earn, and settle on-chain seamlessly. Proud to be building alongside @WatanabeSota and the Startale team to scale this infra. Let’s build and ship!
We're partnering with @NonagonCapital to pioneer agentic payment use cases for @JPYStableCoin, Japan's first bank-backed yen stablecoin. Expect PoCs on agent-to-agent settlements, autonomous purchasing & real-time micropayments.

How long until agentic payments overtake human payments?
Very soon there are going to be more AI agents than humans making transactions. They can’t open a bank account, but they can own a crypto wallet. Think about it.

Researched by an 18 years old entrepreneur and it's a pretty good article. I’m very excited to see his next move!

7/ We avoid companies tethered to rigid SaaS frameworks or isolated tech stacks. We focus on the paradigm shift of AI Agent Economic Activity—seeking founders with a realistic business model and the strategic sharpness to compete at scale. We are calling for the visionaries of Agentic Payments. If you are building the economic primitives for the AI era, we want to hear from you.
