Free to own, paid to depend on

Everything a publisher needs to prove and keep an honest record of their own server is free, and stays free. You pay when you depend on servers you do not own — to be told when they change, to take their history with you, or to build a product on what we observe.

Agents pay per request

An agent with no account can keep going past the free limit by paying for each request in USDC on Base: $0.005 for a search or resolve, $0.01 for an evidence document. Nothing to sign up for, and a caller with an API key never pays per request at all. How it works

What no plan buys

No plan changes where a record ranks or what it says about it. Ranking comes from what we observe and from verified ownership, and verifying ownership is free. The observations are only worth citing as long as nobody can pay to change them.

Prices in US dollars. Subscriptions renew monthly and are cancelled from Billing at any time; you keep the plan until the end of the period you paid for. Checkout and card details are handled by Stripe. Questions: hello@wellknown.network.
