Today, we released x402, to let any agent with a wallet pay for an API without signing up. Below are some of my insights from thinking about crypto agents for the past six months, and why we think x402 will catalyze the next wave of crypto AI innovation

x402 is now available on @AEON_Community on BNB Chain! Note: This post is for informational purposes only and not financial advice. DYOR.

Our DevRel @asimfiles spent this week exploring x402, a protocol that lets agents pay for API access autonomously. He built Vend to test it: an API using Alchemy's data endpoints + webhooks that agents can query and pay for directly. Here's what he learned 🧵

x402 is one of the hottest topics in the crypto industry. Due to high demand, @VandyBlockchain alum @MurrLincoln will be joining us at MBC to give an x402 workshop at MBC 2025.

prediction markets are exciting bc they give consumers access to bet on AI directly: ChatGPT user count Product releases IPO valuations jobs reports earnings instead of tail risks from proxy bets: overinflated OTC OpenAI "stocks" macro drawdowns company drama litigation

x402 lets you attach a stablecoin payment to any web request. We think this will be a big part of the new internet. Try it out in your products with @CoinbaseDev

New tool & video: x402 is hot right now. New standards like x402 need lots of people experimenting. So I spun up AgentBlocks, a forked version of n8n with nodes for x402 basics. Now anyone can try x402 without writing code! Watch me build an x402-gated ETH price API here:

npm install facilitators The drop-in configuration for all x402 facilitators

x402 x ERC-8004 x EigenCloud this is how it all comes together to build the agentic payment stack

one of the fun examples i used for x402 and service discovery was telling your agent to "find me a nice day this week and book me tickets to an outdoor event" now we can do step 1! step 2 coming soon?

Interested in how to build with x402? Join us tomorrow to learn about x402 and build on Solana for the x402 hackathon x.com/i/broadcasts/1rmGPvbrL…

Vanderbilt has put itself on the map as one of the top blockchain clubs, with alumni spanning across Coinbase, Galaxy, Artemis, and much more! @VandyBlockchain recruited over 60 members in the fall and they aim to bring 40 members to MBC on December Dec 5-6th! Insane numbers.

If you're wondering what x402 is, why it's a big deal, and why it is the main narrative on Crypto Twitter right now - checkout the latest episode of the Coinbase Developer Podcast. I interview the protocol's creator, the one and only @programmer, on everything x402!

The x402 Solana Hackathon is live 🔥 It’s time to build at the frontier of payments: internet native, designed for AI $50,000 in prizes across 5 tracks 👇

x402 Gateway live at x402gateway.io , powered by @coinbase @CoinbaseDev @base. No API keys required - just provide your API URL and get instant payment protection. Start with free requests and monetize your API with x402 micropayments. @MurrLincoln @kleffew94 @jessepollak @x402Foundation

after a few months deep in x402, here are the directions I’m most excited for builders to take: 1. Client-Side Integrations – what does UI for the end user look like? this could be MCP servers, or an AI-enhanced web browser, some hardware interface, or B2B workflow. This is then end interface where some user tells an AI agent what to do + what to buy 2. Facilitator Providers – who controls the purse? facilitators are arguably the most lucrative role within the entire x402 workflow. They control how money flows, and the policy engines on whether tx go through. community facilitators with properietary volume will be huge. 3. Vendor Adoption – what can these HTTP 402-enabled agents actually buy? this is a legacy compatibility question - how do we make legacy ecommerce services (like Amazon purchases or NYT subscriptions) compatible with x402? could be through some proxy server/relay mech. this hugely expands the pool of resources that x402 agents can buy - but can be difficult to achieve without first-party vendor support 4. Underlying Stablecoin Rails – how is the payment processed? things like stablecoins payin/payout, payment orchestration (Stripe/Bridge), real-time FX settlements that improve the stablecoin settlement stack will ultimately also benefit app-layer innovations as x402. if you're a builder building in any of these directions (or know companies building these) please reach out in comments and DMs!
