Pay it. Any x402 client will do.

The terms, plainly

The 402 is the quote

An unpaid POST is answered with the exact price for that body, in x402 v1 and v2. Reading it is free.

You pay at submission

Settlement happens when the job is accepted, not when the file lands. A job that fails is resubmitted once, automatically.

Failures are reported, not hidden

A job that fails after its automatic retry says so in its status, with the reason. Write to support@kino402.com with the job id.
