The best place to develop your x402-enabled agent, hands down, is @CoinbaseDev. - Wallets with configurable custody; API-key driven or end-user driven - On/offramps built-in - Native x402 facilitator to make payments trivial If you're using x402, build with CDP! Link in 🧵
the average vibecoding experience changes when you give an agent a wallet with x402 - sonnet/opus doesn’t generate images? just pay an image generation provider per request (it would cost ~$0.05) - need transcription for audio ? ask the agent to find a service on the x402 marketplace - want to feed an article about FHE to your agent, but cloudflare blocks access? use a firecrawl x402 endpoint giving agents access to money unlocks an entirely new layer of capabilities

Real-time web search, agent-payable in USDC on @base, no API key or account needed. → Claude agent built by @Must_be_Ash reads the day's news for $0.10, built with x402 and @tavilyai. Partnerships: → @PPRO_Payments integrates Coinbase Payments, bringing stablecoin acceptance to enterprise merchants. Events: → Join us at @money2020 in Amsterdam next week: Panel 1 with Alaina Revoir: "Unlocking Value: Digital Assets in Institutional Payments," Tuesday June 2, 11:10, Intersection Stage.

Update: I’ve left Coinbase. I’m starting a company. I’ll continue to be involved with x402 as a member of the Technical Steering Committee with the foundation, and as an advisor to Coinbase on agentic commerce. I’m incredibly proud of the work we’ve done in @CoinbaseDev. It's truly an elite team executing at the highest of levels. Many exciting things coming soon 👀. @yugacohler will be taking the helm as Head of Engineering, he’s a rockstar, he’ll crush it. It's been an exceptional second tour of duty at Coinbase. It was a hard decision to leave, but there's an idea in my head I need to get into the world. Big thank you to @barmstrong, @emiliemc and @nemild for bringing me back, and to @alecglovett, @yuga @brian__foster and everyone else in CDP - it's been an honour.

AWS 🤝 x402 & Coinbase what makes me optimistic that agentic payments are here to stay is how quickly some of the biggest companies in the world are jumping onboard.

Every agent deserves a wallet. So we’re helping every dev on Amazon Bedrock AgentCore give their agents one. Autonomous spending, budget controls, built-in compliance, and USDC settlement on @base. This is the future, powered by x402.

Incredible to see all the recent improvements to the x402 protocol 🤯 - Algorand SDK - Hedera SDK - Go middleware (Echo net/http) - Fastify middleware - UpTo in Python - Bazaar search Most of these were community-driven, which is why open protocols win 🧵

The storefront of the agentic economy is live 🔥 A streamlined and snappy web UI for humans, and a rich MCP for agents to find x402-enabled products. Check it out!

x402 Bazaar v2 > Semantic Search: just describe what you need > Filters: narrow results by price, asset, chain > Quality Signals: think PageRank for APIs > MCP with proxy_tool_call: search in natural language, call any service as a tool. No need to know how the endpoint works.

Big scalability improvement for agentic payments: x402 "Upto". Pre-authorize up to an amount, use as much as you want, the final amount gets settled onchain.
A new way to bill AI agents just dropped: the x402 upto scheme 🤖💸 x402 is the HTTP 402 standard for machine-to-machine payments. Until now, it only supported fixed pay-per-request pricing. Here is why the new `upto` scheme changes everything 🧵👇

Usage-based pricing is now live on x402! The new "Upto" scheme lets agents pay only for what they consume, unlocking variable-cost services like LLM inference, compute, and data queries on x402. Available now on the x402 SDK CDP Facilitator. ↓
