Explore who paid whom, how much and how often in the frozen June 1, 2026 x402 payment snapshot on Base.
The x402 snapshot explorer for payments on Base
x402 is an onchain protocol that lets AI agents pay for APIs and services programmatically, settling in USDC on Base. lookx402 presents archived observations from June 1, 2026, so you can explore agents, behavioral archetypes, top services and the state of x402. What is x402?
x402 is an open protocol from Coinbase that lets AI agents pay for online services without human approval. It uses crypto wallets · mostly USDC · on chains like Base, Solana, and Stellar. Behind the scenes, it's HTTP error 402 · Payment Required turned into a standard way for machines to transact.
When an AI agent calls an API, the server can respond with a 402 instead of the data. The agent signs a payment authorization and retries with proof of payment. lookx402 displays archived observations from the June 1, 2026 snapshot.
Why this matters
Until now, AI-agent payments happened in the dark · between machines, in HTTP headers, invisible. With x402 settling on a public blockchain, every transaction is recorded forever. That changes the conversation.
Companies deploying agents can finally see what their bots are doing with the budget. Journalists can watch the agent economy emerge in public. Compliance teams can trace flows. Researchers can study M2M (machine-to-machine) economies as they happen. We don't speculate on what AI will do · we map what it's already doing.
Frequently asked
What exactly is an AI agent?
An autonomous program · like a coding assistant, trading bot, or research agent · that has been given a crypto wallet and the right to spend on its own. It calls APIs, buys compute, pays other agents · without a human clicking 'pay' each time.
Why are most of the wallets anonymous?
A wallet address does not establish the identity of a business or prove that its payer is an autonomous agent. The profiles reflect the frozen June 1, 2026 dataset. Any labels are dataset annotations, not identity verification; no current anonymity percentage is established here.
How accurate is your data?
The published counts and profiles reproduce observations in the frozen June 1, 2026 dataset. Individual payer and recipient profiles require at least 30 recorded payments. Read the methodology for coverage and limits; this snapshot does not measure a current indexing interval or guarantee complete current activity.
Are you affiliated with Coinbase, OpenAI, Anthropic, or a facilitator?
No. lookx402 is an independent public observatory. The data is public on-chain · anyone could build this. We just made it readable.
What about Solana, Stellar, or other chains?
The published payment snapshot covers Base as of June 1, 2026. It does not establish current coverage or market shares for other chains.
Can I export the data or get alerts?
The published statistics and profiles use the June 1, 2026 snapshot. Consult the methodology for the scope of available data; current export and alert services are not verified here.
