AI agents are becoming a real traffic and purchase source. Here's how to make your products findable and buyable by agents — and what happens when an order arrives.

AI agents are buying products on behalf of real people right now. To sell to them, you need two things: your catalog needs to be machine-readable so agents can find your products, and you need a checkout path an agent can actually complete without hitting a CAPTCHA or a fragmented payment flow. This guide covers both, with a focus on what sellers can do today.

## Why AI Agents Are a New Traffic Source

Search traffic has been fragmenting for years. AI assistants now answer product questions directly, and when they have purchasing capability, they skip the browse-and-click loop entirely. A buyer agent given the task "order me three cases of 4-ounce amber glass jars, under $40 shipped, from a small business" will query a structured product index, compare options, and place an order — all without visiting a storefront.

This is different from organic search or paid ads. The agent doesn't read your homepage copy, react to your brand photography, or respond to a discount popup. It reads structured product data: title, SKU, price, weight, dimensions, availability, shipping time. If that data isn't exposed in a machine-readable format, your products are invisible to it.

Being visible is step one. Being *buyable* — meaning the agent can complete a purchase without a human manually intervening on the checkout page — is the gap most sellers haven't closed yet.

## Agentic SEO: Getting Found Before You Can Be Bought

Optimizing for agent discovery is sometimes called agentic SEO. It shares some DNA with traditional structured data work, but the intent is different: you're writing for a system that parses, not a user who reads.

Practical steps:

- **Structured product markup.** Schema.org `Product` and `Offer` markup on product pages gives agents machine-readable price, availability, and identifier data without scraping.
- **Accurate product feeds.** A clean, current product feed (Google Merchant Center XML, or a well-structured JSON feed) is the most reliable signal. Agents that query product indices pull from feed data, not page copy.
- **llms.txt.** A plain-text file at `/llms.txt` on your domain that describes what your store sells, who it's for, and how to interact with it programmatically. [Firestarter publishes one](https://firestarter.network/llms.txt) as a reference.
- **Descriptive product data.** Agents parse titles and descriptions for attribute matching. "4 oz Amber Glass Boston Round Bottle with Black Lid — Pack of 12" resolves far better than "Amber Bottle Pack."

None of this requires a technical overhaul. It's largely a data hygiene and metadata problem.

## Three Ways to List on Firestarter

Once your catalog is structured, the next step is listing it where buyer agents actively query. [Firestarter](/sell) is a two-sided commerce network: buyer agents query it for products, seller agents manage inventory through it. Sellers can get listed three ways.

### 1. Connect Your Existing Store

If you're on Shopify, WooCommerce, BigCommerce, Wix, or Squarespace, Firestarter auto-detects your platform and pulls your catalog automatically. The process takes about 30 seconds: you authenticate, Firestarter reads your product feed, and your inventory is live in the network.

Your product data syncs — price changes, stock updates, new SKUs — so agents always see current availability. Orders placed through Firestarter appear in your existing store admin just like any other order, with no separate fulfillment workflow to manage.

### 2. CSV or JSON Bulk Upload

If you're on a custom platform, a headless stack, or managing inventory outside a traditional storefront, you can upload a product catalog directly. Firestarter accepts standard CSV or JSON formats. The [seller documentation](/seller) has the field spec, but the required fields are minimal: title, SKU, price, currency, and availability. Everything else — images, weight, dimensions, shipping class — improves agent matching but isn't required to list.

Bulk upload works well for wholesale catalogs, B2B suppliers, and sellers with large static inventories that don't need real-time sync.

### 3. Point Your AI Agent at /SELL.md

This path is designed for sellers who are already using AI agents in their operations — or want to. [Firestarter's /SELL.md file](https://firestarter.network/SELL.md) is a machine-readable skill file that a capable AI agent can read and act on. Point your agent at that URL and it can register a seller account, list your products, and manage order responses entirely programmatically via the seller API:

```
POST /seller/register       — create seller account
POST /seller/stores         — connect or describe your store
POST /seller/products/create — list individual products
GET  /seller/orders         — retrieve incoming orders
GET  /seller/feed           — retrieve your live catalog feed
```

This is the agentic-native path: your agent manages your storefront the same way a buyer's agent places orders. No human needs to log in to a dashboard.

## How Agent Orders Arrive and Settle

When a buyer's agent places an order through Firestarter, here's what happens on the seller side:

1. The buyer agent submits a purchase execution via `POST /v1/executions`.
2. If the buyer has a human approval checkpoint enabled (it's on by default), the execution pauses for human sign-off. The buyer confirms; nothing is charged until they do.
3. Payment is held in escrow via Stripe. The seller receives funds after delivery confirmation, not at order placement. This protects both sides.
4. The order appears in your Firestarter seller dashboard and, if you connected a store, in your existing store admin. You fulfill it like any other order.
5. Firestarter generates a shipping label via EasyPost. Tracking updates flow back to the buyer agent automatically.
6. On delivery confirmation, funds release from escrow and settle to your Stripe Connect account.

Exception handling — failed deliveries, returns, disputes — is managed through the execution API so buyer agents can act on it programmatically rather than opening a support ticket.

## What the Founding Seller Program Offers

Firestarter's founding seller program locks in 0% commission for the first 12 months. It's capped at 10 sellers per product category to avoid diluting placement quality. Sellers who join early get priority ranking in agent matching — meaning their products score higher in the comparison step before a buyer agent presents options.

For context on fees: Amazon's total fees run 30–45%, Etsy's run 12–20%, TikTok Shop runs 8–10%. Firestarter's standard rate after the founding period is a [3% commission on completed sales only](/pricing) — no listing fees, no monthly storefront fees.

Standard pricing: free tier includes 100 tokens to start plus a 14-day Pro trial, no credit card required. Pro is $99/month with 10,000 tokens. Sellers list free and pay a 3% commission on completed sales only. Buyers pay no transaction fees.

## The Structural Shift

Selling to agents isn't a niche technical exercise — it's the next distribution channel. The sellers who figure out structured data and machine-readable catalogs now will have the same advantage that early Shopify adopters had over sellers who stayed on static HTML sites. The checkout infrastructure problem is already solved; the catalog discovery and listing work is what's left.

## FAQ

### Do I need a developer to list on Firestarter?

No. The store connect path (Shopify, WooCommerce, BigCommerce, Wix, Squarespace) requires no code — just authentication. CSV/JSON upload is a spreadsheet-level task. Only the /SELL.md agent path requires a capable AI agent or developer work.

### What happens if an item goes out of stock after an agent submits an order?

The execution enters exception handling. The buyer agent is notified, and the execution can be cancelled or re-sourced. Funds held in escrow are returned if the order can't be fulfilled.

### How does payment work for sellers?

Payment is held in Stripe escrow from order placement until delivery confirmation. Funds then settle to your connected Stripe account. You're not paid at order time — which also means you're not exposed to chargebacks from unfulfilled orders.

### Can I list digital products or services, not just physical goods?

Firestarter's current infrastructure — EasyPost shipping labels, delivery confirmation — is built around physical goods. Digital products and services are not supported in the current version.

### How do agents find my products specifically?

When a buyer agent submits a purchase intent, Firestarter's matching layer queries the seller catalog index for products matching the described attributes (type, price range, quantity, specifications). Sellers with cleaner, more attribute-rich product data get better matches. Priority placement in the founding seller program also affects ranking.
