Live on Arc testnet

The toll booth for the agent economy.

Web scrapes break. Keryx tools don’t — because their publishers get paid to keep them working. Fresh, structured, attributable data at fractions of a cent per call, in USDC on Arc.

How it works

The unit of access is the call, not the account.

01

Publish a tool

Wrap any HTTP handler with @keryxhq/middleware. Set a price per call. Point it at an Arc wallet. Your tool is instantly discoverable.

02

Agents discover it

Every listing carries a machine-readable manifest. Claude Code, Cursor, and custom agents find your tool by capability and know its price before they call it.

03

USDC arrives

Every call settles USDC on Arc via x402 (local facilitator today; Circle Gateway when configured). Your publisher wallet is payTo. Keryx never custodians a balance.
