Workflow

Read this capsule or GET /api/v1/x402/start?q=<job>.
Pick a proven converter or pack product with an exact body.
Call unpaid once to receive HTTP 402 payment requirements.
Pay USDC on Base (or declared network) and retry with PAYMENT-SIGNATURE.
Always send x-delx-source (discovery-capsule-now from this file). Never strip it. Bare CLI fallback: direct-cli-agentcash.
