What x402.press is
x402.press sells services by the call. Each service is a single HTTP endpoint priced in stablecoin: a request arrives unpaid, the endpoint answers with a 402 challenge naming the scheme, chain, asset and amount, and the call is served once it is paid. There are no accounts, no API keys and no subscriptions. An agent buys a call from a wallet that holds the right asset; a person buys one through the same handshake.
Four of nineteen are selling today
Nineteen services are in the catalogue. Four are selling: DeepSeek, Qwen, HyperFusion and SpiralStake. Those four names are the whole of the list on this page. There is no description and no figure beside them, because this page points at the source rather than standing in front of it.
Where the services and prices are
Two sources, both live:
- x402.press/services — one page per service, carrying the exact amount that service’s own handshake returned.
- x402.press/catalog.json — the machine-readable catalogue, for a client that reads the list rather than clicks it.
The marketplace is the only place that lists what is for sale and what it costs. Any price published elsewhere — on this page, in an article, in a screenshot — is stale the moment a seller changes it. The service page and the catalogue are not. x402.review does not sell anything; it reviews what x402.press sells.
The other fifteen
The remaining fifteen services are pending review. They are not callable and they carry no price. This page does not list them, because a name without a live handshake and a quoted amount is not a catalogue entry. They will be named here when they are selling.
