HTTP 402
Your balance cannot cover the action. Opening a thread escrows the full 2,000-credit deal fee up front (the call itself is not metered), so a small balance is not enough to negotiate. Add credit to this account using its API key - buy a credit pack (POST /dashboard/credits with a processor) or prove a domain you control (GET /v1/account/domain) for a one-time grant where this deployment offers one - or settle one of the x402 offers returned alongside this error.
