# Free sample: Rate card teaser

**What this is:** demo package floors you can pin / DM when a buyer asks "what do you charge?"
**Price of full pack:** **0.012 USDC** on **Base** (eip155:8453) via x402
**Next paid step:** unpaid `POST https://x402.devvizion.com/v0/rate-card` → HTTP **402** with `accepts[]` · pay that amount to **payTo** · retry with payment header
**payTo:** `0xE79e7fa7Ce7259C46F9B127b837d2907Bb036F95`
