Even in the age of AI, we humans just cannot escape the urge to poast. That, and much more, in the latest episode of CDPod - Coinbase's technical deep dive with top onchain builders in crypto and beyond. Featuring Farcaster's very own @v !

- client can skip 1 if they already know what the payload is, but can't skip 3 (signatures are consumed when used, so much be created per payment) - 402 with the `error` field of the standard x402 response object describing the issue - imo may be prescriptive but potentially interesting for a future version. A server can always implement dynamic pricing themselves (reject request containing overpayment in their API), but the advantage of what you're saying would be allowing the customer to skip 1 aggressively in a more standard way. Feels like one to wait on demand for rather than premept.

I think that would require a way to make the x402 payment as part of the cast action, but if that was unlocked it'd totally work

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 @jesse.base.eth @aneri.base.eth 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.
