What to do for each tuple (chain, scheme) is defined in the spec, and clients implement the spec That x402 isn't opinionated on, the rest is up to the HTTP server accepting x402. Any part of http or standards on top of http (OpenAPI, MCP, HTML) are valid in the response to the request making payment

I can help here! x402 standardizes a response that describes how to const payment, and a header the includes a payment. The client creates the X-Payment payload based on the response body. There are other details like delegating settlement to the facilitator, but broadly thats it for the http exchange.

x402 is an extension of 402. Would love to enshrine it as a formal w3c standard but gotta start somewhere. Facilitators perform kyt, kyc isn’t required because the facilitator never holds funds. Facilitator is a documented standard, there’s an oss example one in our repo, anyone can deploy. Consumer validation is now, CDP has seen demand for a way for agents to seamlessly pay via our project agentkit and other places, but the time is now to see if this is the right approach.

Happy to chat in dms or at the eth Vancouver meetup. Agree on hype which is why x402 works live in production today

They’re unrelated. That standard focuses on merchant payments for e-commerce. X402 is lower level, arbitrary payments over http

Great question, I suspect because the Base team tests increases before they hit mainnet but @jessepollak @aneri would know best

Today, we're launching a new payments protocol that enables developers and AI agents to access and pay for APIs without API keys. x402 gets its name from HTTP Status Code 402 (Payment Required), and is built onchain. The new era of the internet will be powered by crypto. Read more at x402.org.

We think agents will make independent decisions on what developer tooling to use when building software. As a result, all Neynar APIs now accept micro crypto payments. No need to - create a developer account - create API key - give API key to LLM agent If building on Farcaster or Base, any LLM agent with a crypto wallet can now ping our APIs, send USDC on @base and get back an API response.

Technically: - x402 lives as standardized response body + status code (402: Payment Required) - payments are signature based, encoded as a header (meaning no gas for the payer, if you've got usdc in your @farcaster wallet, you can buy stuff) - servers don't need RPC or a wallet online, they can delegate onchain actions

Over at @coinbasedev we just dropped @x402, an open standard for payments on the internet. Why does this matter? - Paying for things on the internet sucks - API keys are terrible UX for AI agents - fees are too high x402 makes paying 3 clicks, kills API keys via pay per request, and has 0 fees.

First x402 demo in the wild. Amazing work by the Neynar team 👏 If you want to enable fully autonomous payments for your API without any API keys, DM me.

Excited to launch our new developer wallets. 🔥 Lightning fast. Secure. No key management needed. Base, all EVM and Solana compatible. At @coinbasedev we're going to keep making it trivial and safe to build onchain whether you have hundreds or millions of users. 👇
