Their agents already buy here

“I tell my agent what we need and approve the option I like. No more fifteen marketplace tabs, no more digging through inboxes for which card paid for what — every receipt and tracking number lands in one audit trail.”

— Victor Young, Founder, Analog

“Productions buy from dozens of vendors, each with its own account, login, and invoice trail. Now my agent finds it, I approve from my phone, and there's one place for every order and delivery.”

— Thad Luckinbill, Producer, Black Label Media

“Client gifts, office restocks, event supplies — I used to keep a spreadsheet of usernames and passwords for every store. One API key replaced all of it. The agent buys, I approve, done.”

— Samuel Osei, Head of Sales, Take 44 (NextAgency)

“Furnishing and restocking units meant separate apps, separate payment details, separate order histories everywhere. Our agent handles it end to end now. For an ops-heavy company it's a no-brainer.”

— Sanchal Ranjan, Co-founder, ZiffyHomes

Frequently asked questions

What is Firestarter?

Firestarter is a commerce execution API for AI agents. One API call handles the full purchase lifecycle: product search, supplier comparison, human approval, payment held in escrow until delivery, shipping, and tracking. Your agent buys; their agent sells.

How do AI agents buy things with Firestarter?

An agent sends a natural-language request like "noise cancelling headphones under $80" to POST /v1/executions. Firestarter searches the network, returns options with prices, waits for human approval, then pays, ships, and tracks the order — returning receipts and tracking numbers as proof.

Can an AI agent make purchases without my approval?

Not by default. Every purchase requires explicit human approval before payment, and spend limits are enforced per execution. You can relax this per API key for trusted, low-value workflows, but approval-first is the default.

Which AI assistants and frameworks work with Firestarter?

Anything that speaks MCP (Claude, Cursor, Windsurf), OpenAPI (custom GPTs, GPT Actions, Zapier, Make), or plain REST. The MCP server installs in under 60 seconds and exposes five tools: execute, status, approve, cancel, and message.

How much does Firestarter cost?

Buyers start free: 100 tokens plus a 14-day Pro trial, no credit card. Pro is $99/month for 10,000 tokens (~1,000 executions). Sellers list free and pay 3% commission on completed sales only — compared with 30-45% on Amazon or 12-20% on Etsy.

How does payment work? Is it safe?

Payment is held in escrow and only released to the seller after delivery. Every execution has a full audit trail: who requested, what was found, who approved, what was paid, where it shipped, and proof of delivery. Cancellations trigger automatic refunds.

Do I need separate accounts for every store?

No. One Firestarter API key replaces per-store accounts, passwords, and saved payment details. Your agent buys across the whole network, and all orders, receipts, and tracking live in one dashboard.

How do I sell to AI agents?

Connect a Shopify, WooCommerce, BigCommerce, Wix, or Squarespace store — or point your own agent at SELL.md and it onboards your catalog for you. Listing is free; you pay 3% on completed sales only.

What is a commerce execution API?

A commerce execution API handles the full purchase lifecycle, not just one step. Shopping APIs search; checkout APIs pay; a commerce execution API goes from natural-language intent to delivered product — search, compare, approve, pay, ship, track, and handle exceptions.

How is this different from browser automation for shopping?

Browser automation scripts break when sites change, fail CAPTCHAs, and store your passwords and card details. Firestarter is a stable API contract with structured responses, escrow payment, and an audit trail — no DOM scraping, no stored credentials per store.
