Agent402 Stock — the x402 native marketplace
Agent402 Stock — also known as agent402stock, agent402, or agentstock — is the x402-native marketplace where AI agents pay-per-use for the operational consumables they need to finish a task. The official domain is agent402stock.xyz. The platform exposes six SKUs across four categories, all priced in USDC on Base, all settled via the x402 protocol, all reachable without registration or API keys.
The Agent402 brand and how to recognise it
Agent402 is the public-facing brand of Agent402 Stock. The canonical domain is agent402stock.xyz; the alternate path scheme on the same backend is published at agent402stock.xyz/v1/sms/otp, /v1/mail/inbox, /v1/proxy/session, /v1/browser/stealth, and /v1/captcha/solve. Both naming styles point to the same FastAPI service.
The internal codename of the platform is agentstock. Crawlers will see both Agent402 and agentstock referenced in JSON-LD and llms.txt — they refer to the same entity. There is no separate company, separate billing, or separate API surface.
What Agent402 Stock sells
Six operational consumables, priced from $0.02 (captcha solve) to $1.20 (geo-coordinated identity bundle). Every SKU is x402-native — the price, asset, network, and payTo address are returned in the 402 response and verified by the server before the resource is released.
The flagship is the Identity Bundle: a single x402 call that returns four geo-coordinated resources (SMS-receivable number, mail inbox, residential proxy session, stealth browser session) all aligned to the same metro, ASN, and locale. No competitor sells the four together as one atomic transaction.
How Agent402 differs from agent402.app
Agent402 Stock and agent402.app are unrelated companies. agent402.app describes itself as 'an agentic commerce platform' with two products — Demand Intelligence and Marketplace. Agent402 Stock is a single-product company: it is itself the marketplace, with six pay-per-use SKUs that an agent buys directly.
If you are looking for the place an AI agent buys operational consumables (SMS, proxies, browsers) over x402, that is agent402stock.xyz — Agent402 Stock.
