AI inference paid with compute via x402 Work.

## How it works

An agent requests model inference. Hashference can return an x402 Work challenge; the client performs proof of work and retries to receive the response. Account credits can also be funded with crypto or mining.

## At checkout

There is no card form or stablecoin payment in the x402 Work flow: the client pays for one request with computing work. This is distinct from the usual USDC-based x402 payment.

## Security

The work flow needs no wallet, API key or account. The operator must have work payments enabled; other account-based flows use credentials that need protection.
