Firestarter — Commerce Execution API for AI Agents

One API call to find, buy, ship, and track any product. Your agent buys. Their agent sells.

Give your AI agent the ability to buy things

Firestarter handles the full purchase lifecycle: product search, supplier comparison, human approval, payment held in escrow until delivery, shipping labels, tracking, and exception handling.

curl -X POST https://api.firestarter.network/v1/executions \
  -H "Authorization: Bearer fs_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"request": "noise cancelling headphones under $80", "budget": {"max_total": 80}}'

How it works

  1. Understand intent — your agent sends one natural-language sentence; Firestarter parses product, constraints, and budget.
  2. Search & compare — the network is searched and suppliers are compared on price, shipping, and ETA, returning structured options.
  3. Match & purchase — after human approval, payment is taken and held in escrow until delivery.
  4. Coordinate fulfillment — shipping labels, tracking numbers, delivery confirmation, and exception handling, all on the same execution.

Works with your stack

One platform: shop, sell, or build

Shoppers

Find products with AI search, get personalized recommendations, and never miss a deal. One API key replaces per-store accounts, passwords, and saved payment details.

Sellers

Optimize pricing, automate negotiations, and manage inventory with AI agents. Your products become buyable by every agent on the network.

Developers

Build commerce into any app with our APIs, SDKs, and automation tools. One execution endpoint covers the full purchase lifecycle.

Sell to AI agents

Connect your Shopify, WooCommerce, BigCommerce, Wix, or Squarespace store (auto-detected, about 30 seconds), upload products via CSV/JSON, or point your own agent at SELL.md and it onboards for you through the seller API. Free to list, 3% commission on completed sales only — you keep 97% of every sale. Founding sellers pay 0% for their first 12 months, capped at 10 sellers per category.

Safe by default

Every purchase requires human approval. Spend limits per execution. Full audit trail with proof of action: receipts, tracking numbers, delivery confirmation. Payment is held in escrow and only released to the seller after delivery; cancellations trigger automatic refunds.

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.

What are tokens and how many does a purchase use?

Tokens meter usage. Creating an execution costs 10 tokens and approving it costs 10 more, so a completed purchase uses about 20. Free accounts start with a one-time 100 tokens; Pro includes 10,000 tokens per month; top-up packs are 500 for $9.99, 2,000 for $29.99, or 5,000 for $59.99.

Is searching for products free?

Yes. Product search costs no tokens. You spend tokens only when your agent creates an execution and when you approve it, so browsing options and comparing suppliers is always free.

Do buyers pay transaction fees?

No. Buyers pay no transaction fees and no markup on products; buyer usage is metered in tokens. The 3% commission is paid by sellers, and only on completed sales.

What happens if my order never arrives or arrives damaged?

Payment is held in escrow and is not released to the seller until delivery, so a missing order means the seller doesn't get paid. Exceptions like damage or non-delivery are handled per execution with the full audit trail as evidence, and cancellations trigger automatic refunds.

Can I set a spend limit for my agent?

Yes. Spend limits are enforced per execution, and every request carries an explicit budget (for example {"budget": {"max_total": 80}}). Options above the budget are never purchasable, and approval is still required before any payment.

Can a custom GPT buy things through Firestarter?

Yes. Add the OpenAPI spec at api.firestarter.network/.well-known/openapi.json as a GPT Action with your API key. Purchase endpoints are marked consequential (x-openai-isConsequential), so the GPT confirms with you before executing.

What proof do I get that a purchase actually happened?

Every execution returns proof of action: receipts, tracking numbers, and delivery confirmation. The audit trail records who requested it, what was found, who approved it, what was paid, and where it shipped.

Which store platforms can sellers connect?

Shopify, WooCommerce, BigCommerce, Wix, and Squarespace are auto-detected and connect in about 30 seconds. No storefront? Upload products via CSV/JSON or the seller dashboard, or point your own AI agent at SELL.md and it onboards your catalog through the seller API.

What is the founding seller program?

Early sellers pay 0% commission for their first 12 months, capped at 10 sellers per category, with priority placement in agent matching. After that, the standard 3% on completed sales applies.

Does Firestarter work outside the US?

The network is global: live scenarios range from same-day roses in Bangkok to bulk kraft mailer boxes in Austin. Availability for a given product depends on sellers in the network for that category and region, and your agent compares shipping and ETA per option.
