x402 is an open standard (proposed by @coinbase ) for embedding micropayments directly into HTTP headers, enabling seamless AI agent transactions without legacy payment friction.
Here are 5 recent developments (Sep 2025)π§΅
for the past few weeks i've been tracking how the x402 ecosystem has been shaping up

I fixed tipping with those guardrails.
- Retweets and emoji/text in replies/quotes will only be picked up and used for USDC tipping if those actions occur after the enablement timestamp of those features.
- As likes have no timestamp in the action itself, we must process likes
Hi @MurrLincoln , This is my submission to Coinbase Agents in Action Hackathon.
I created x402 enabled api.snack.money/pay API endpoint to pay to X and Farcaster accounts in USDC.
Example Github Repo: github.com/snack-money/agβ¦
Recording: customized example to send you some
working on @snackmoneyapp x402 api endpoint solana support. soon both @base and @solana ai-agents will be able to send snacks(πͺ) to social accounts on X, @farcaster_xyz and github
Coming to @snackmoneyapp x402 endpoint api soon.
sending USDC to social account with natural language. For instance, send it to @farcaster_xyz account with a single prompt.
Your AI Agents with wallets can pay any X account for rewards or just tipping. No Wallet address is needed. Instant settlement thanks to @USDC and @base .
Bonus : It goes directly to @farcaster_xyz wallet if connected.

A small Network Stateβinspired experiment:
A paywalled site where robots.txt itself contains payment instructions β powered by x402-enabled Snack Money micropayments.
π‘ Idea: Instead of bots scraping without permission, they can read

Lincoln!
Thanks a lot for the opportunity. I think you initiated the creation of the x402 market and got so many of us excited about the tech. I still remember the fork I created 4β5 months ago when you added x402 support to Agentkit.
I immediately forked it and tried it
one year ago today i vibe coded the agentkit prototype
today, x402 passed 1 million transactions and $1 million in volume -- with enterprises and startups both onboard
where will onchain agentic commerce be this time next year?
