x402 from zero

ATXP

Agent accounts and paid tools from Circuit & Chisel, a New York startup founded by two former Stripe crypto leads.

Checked 11 October

Our view

A credible, well-funded team that topped x402 leaderboards and then moved on. Its Base payments jumped on the day of a paid press release (16 April) and stopped within two weeks of the next one (10 June), and sampled payer wallets had only ever paid ATXP (x402scan and Base RPC checks). The company now leads with an LLM called Pareto.
