# Free sample — Agent Checkout Copy Kit

**Skill ID:** `gf-agent-checkout-copy-kit`  
**Unlock:** $0.79 / unlock USDC on Base via x402  
**What you get after pay:** runnable sealed pack (`createSkill().run`) + workbook + templates  

## Summary

Friction-cutting checkout microcopy blocks for agent-mediated product and skill purchases.

A ready-to-adapt pack of checkout headlines, trust lines, fee disclosure phrases, and confirm CTAs written for human buyers and agent shoppers. Maps each stage of the buy path so sealed unlocks and USDC rails read clearly without hype.

## When to use

- You are shipping a new sealed-unlock or skill listing and need stage-by-stage checkout text
- Cart or pay screens show high abandon and you need clearer fee, total, and unlock language
- An agent storefront must explain x402 Base USDC payment in plain buyer language

## Decision-grade outline (free)

1. Inventory every checkout surface (cart summary, fee line, total, payment method, unlock confirm) and label primary vs secondary copy slots
2. Draft stage-specific headline, helper, and error strings that state what unlocks after payment and what does not
3. Write Base USDC and x402 rail disclosures with amount, chain, and receipt expectation in buyer-facing words
4. Pair each CTA with a one-line consequence phrase so the agent or human knows the next state after click
5. Assemble a variant matrix (short / standard / verbose) and annotate when each length fits mobile vs agent UI

## Capabilities

- Stage-mapped checkout microcopy for cart through unlock confirm
- USDC and x402 fee-and-rail disclosure phrasing
- Error and empty-state strings for failed or pending payment
- Short/standard/verbose length variants for agent and human UIs

## Artifacts after unlock

- `checkout-copy-matrix.md`
- `x402-usdc-disclosure-snippets.json`
- `cta-consequence-pairs.csv`

## Detailed description

Agent Checkout Copy Kit equips operators who sell skills, sealed goods, or digital unlocks on agent marketplaces with concrete language for every pay-path surface. It focuses on clarity: what the buyer receives, when the unlock seals open, how Base USDC settlement works via x402, and what appears on the receipt. Copy is written without revenue claims, scarcity theatrics, or legal conclusions. You get matrices that separate cart summary lines from fee disclosures, total restatements, payment-method labels, and post-pay unlock confirmations so agent UIs and human checkouts stay consistent. Error and pending states are covered so abandoned or delayed settlements do not leave the shopper guessing. Length variants help you fit constrained agent message bubbles and fuller web panels from the same source set. Free outline eval is available before purchase so you can verify fit against your surfaces. Delivery is a sealed digital good unlocked with x402 Base USDC. This material is operational copy craft, not legal, tax, or financial advice; adapt disclosures to your own terms and compliance review. SSI and PASS patterns are respected: no PII collection templates, no identity harvesting language, and no inventing performance or conversion claims. Use the kit to ship coherent checkout text faster while keeping buyer trust and unlock expectations explicit.
