CartAI
CartAI is a developer-first API that deploys AI agents to complete real transactions on any web property — retail checkout, subscription sign-up, invoice payment or order submission — with PCI-compliant hosted payments and affiliate commission tracking built in.
What is CartAI?
CartAI is a transaction-execution layer for AI agents, published by CartAI, LLC, a Texas limited liability company based in Plano. It describes itself as Agentic Commerce as a Service: a single API that deploys a specialised agent able to navigate any web property and carry an order through to confirmation — a retail checkout, a subscription sign-up, an invoice payment, a purchase-order submission, or any workflow sitting behind a login.
The company places itself deliberately between two adjacent markets. General browser automation can navigate anything, but treats a cleared transaction as one task among many. Agentic payment rails handle identity and money, but still need something able to reach the payment step. CartAI claims the narrow ground in between, arguing that the hard part is not the click but everything between the click and the confirmation.
Four products cover that ground. Catalog searches products across merchants, returns every variant with its stock and price, and prices a basket before any cart exists. Checkouts submits an asynchronous task that an agent runs on the merchant's own site, and a single task can span multiple SKUs at multiple retailers. Payments issues a hosted, PCI-compliant session so card data never touches the customer's servers, DOM or logs. Monetization captures affiliate commission on the products surfaced and the orders cleared, then shares the revenue back.
Three engineering claims underpin the promise: composable workflows with conditional branching and retry-safe idempotency; a PCI-compliant intake and tokenised vault, with single-use payment tokens issued through Visa Intelligent Commerce and Mastercard Agent Pay; and cooperative bot mitigation — CartAI states it does not evade Cloudflare, HUMAN or Fingerprint, but identifies itself through Web Bot Auth and Skyfire KYA.
There are three ways to integrate: the REST API on api.cartai.ai, an open-source MCP server released under Apache 2.0 for hosts such as Claude Desktop, Claude Code, Cursor and VS Code, and a drop-in Hosted Cart still announced as coming soon. The homepage displays orders the company says cleared at BestBuy, Newegg, Jomashop and Ulta. The domain was registered in July 2025 and the founder is named on the blog as Manil Uppal.
What it does
- Complete a checkout on a merchant's live site, from cart to order confirmation
- Run one task across several SKUs and several merchants at once, with an agent per merchant
- Search products across thousands of merchants and return variants, stock and live prices
- Estimate a full basket — subtotal, shipping and itemised tax — before any cart is created
- Collect and tokenise a card through a hosted, PCI-compliant payment session
- Stream every state change of a transaction back through webhooks, up to confirmation
- Capture affiliate commission on products surfaced and orders cleared, with attribution preserved
When to use CartAI / When not to
A quick filter to help you decide if CartAI is the right fit.
When to use CartAI
- Engineering teams building AI shopping assistants or copilots that must place orders, not merely recommend them
- Publishers, editorial media and affiliate platforms that want product mentions to convert in place, without a redirect
- Product teams behind vertical AI apps such as gift finders, recipe-to-cart tools, virtual closets or travel planners
- Marketplaces, aggregators, influencer platforms and cashback or loyalty apps that need branded checkout with attribution preserved
- B2B operations and procurement teams automating purchase-order submission, vendor portals and invoice or utility bill payment
When not to use CartAI
- Non-technical buyers looking for a ready-to-use application: everything runs through an API integration or an MCP server
- Anyone who needs a predictable, published price before committing, since no pricing page exists and fees are negotiated or shown only in the account dashboard
- Businesses that expect the vendor to stand behind pricing, stock, delivery, returns or refunds, as CartAI is never the merchant of record
- Teams handling European personal data under a strict compliance checklist, given the absence of any GDPR statement, DPA or subprocessor list
- Mobile-first or browser-extension use cases, and anyone under 18, since no app exists and the Terms require adult users
How to use CartAI
A typical end-to-end flow, from setup to results.
- Create an account on the CartAI portal with your name, email and a password, which opens the developer dashboard
- Note that a single environment covers both testing and production: there is no separate sandbox URL to manage
- Stay in test mode for development, where cards are not tokenised, and use the sample card 4242 4242 4242 4242, expiry 12/34, CVV 444 — never a real one
- Open the API Keys section of the portal, click Generate New Key, and store the key somewhere safe
- Authenticate every request with the X-API-Key header against the API base at api.cartai.ai
- Call the Catalog endpoints to search a product, pull its variants and estimate the basket total before creating any cart
- Create a payment session server-side, then either redirect the customer to the hosted URL or embed it in an iframe with allow=payment
- Pass the returned session identifier into a checkout task, together with the customer contact, shipping address and items
- Subscribe to webhooks in the Admin portal, securing your endpoint with Basic Auth or OAuth, and follow the task to confirmation
- Request production features through the Request Go Live button, then accept the clickwrap agreement once CartAI has reviewed the request
Pros & Cons
Pros
- Named, verifiable-looking proof: the site shows orders it says cleared at BestBuy, Newegg, Jomashop and Ulta rather than staged demos
- PCI scope stays off the customer's stack, since cards are entered in CartAI's hosted interface and never reach the customer's servers or logs
- Bot protection is met head-on through signed agent identity and KYA rather than evasion, which is a far more durable posture
- Full observability: one webhook per state transition, with a payload normalised across every supported merchant
- No scraper maintenance, as CartAI takes ownership of the extraction layer across supported merchants
- Affiliate attribution survives the agent, and can even be earned without running the checkout at all
- Fast, free first contact: sign up, generate a key, and run a simulated transaction in test mode within minutes
Cons
- No published pricing at all: no pricing page, no rate card, no entry price, and fees expressed only as basis points on GMV
- No free plan or free trial is announced; the sandbox account is offered as-is, for evaluation only and with no uptime guarantee
- Nothing is guaranteed about outcomes: failed, incomplete or duplicated transactions caused by third-party systems are expressly disclaimed
- Liability is capped at the greater of three months of fees or one hundred US dollars, with mandatory individual arbitration in Texas
- European compliance is thin: no GDPR statement, no Article 27 representative, no published DPA and no subprocessor list
- Parts of the promise are still ahead: the Hosted Cart and American Express support are both announced as coming soon
- Support has no dedicated channel beyond a contact form, a general address and a legal address, and no phone or help centre
Pricing & Plans
No permanent free plan and no free trial are announced. CartAI publishes no price list: /pricing returns a 404 and the sitemap contains no pricing page. The Terms of Service state that fees apply to production API usage according to the schedule shown in the account dashboard or as separately agreed, and that they are based on transaction volume — expressed as basis points on gross merchandise value — and/or other usage metrics. Prices may be revised with reasonable notice to active customers, taxes are borne by the customer, and cancellation gives no right to a refund of fees already paid. Consequently no starting price and no currency can be quoted.
- open to developers without a formal production agreement
- provided as-is for evaluation only
- with no uptime guarantee and no live transactions using real payment instruments
- activated through the Request Go Live button and a clickwrap acceptance
- billed on production API usage as basis points on gross merchandise value and/or other usage metrics
- custom pricing
- SLA commitments and other negotiated terms
- formalised in a separate written agreement that prevails over the standard Terms where the two conflict
Data, GDPR & hosting
A consolidated view of how CartAI handles your data.
GDPR overview
The word GDPR appears nowhere on the site, and the coverage is visibly built for United States law. The privacy policy nonetheless carries a section on legal bases for processing in the EEA and the UK — contract performance, legitimate interests, consent and legal obligations — and states that residents may request access, correction, deletion, restriction or portability by writing to legal@cartai.ai, and may complain to their local supervisory authority. CartAI declares itself established in the United States, processing data there and in other countries, with standard contractual clauses used where the law requires them. No Article 27 representative and no data protection officer are named, no data processing agreement is published, and no subprocessor list is available. The California CCPA and CPRA disclosures are far more developed than the European ones.
Who owns the data?
Under the Terms of Service, customers keep ownership of the Customer Data they submit, and grant CartAI only a limited licence to process it in order to run the service, prevent fraud, improve reliability and comply with the law. CartAI and its licensors own the platform itself — software, code, APIs, interfaces and branding — and any feedback a user sends becomes CartAI's to use perpetually and free of charge. For end-user data captured in a checkout flow, CartAI declares itself a CCPA service provider acting on the customer's instructions, leaving the customer responsible for collecting consent. Raw card numbers are never held by CartAI: a PCI-compliant vaulting partner keeps them and returns a token.
Reuse rights
The Terms give the customer a limited, revocable, non-exclusive and non-transferable licence to use the service for its intended purpose, and nothing more: data drawn from the platform may not be used to build a competing service, to run competitive benchmarks, or to be scraped outside the authorised APIs, and the service may not be resold, sub-licensed or white-labelled without written consent. Customer Data itself stays the customer's, so it can be reused freely in the customer's own product, provided end-user consent has been obtained. On CartAI's side, the privacy policy lists operating the service, pre-filling checkout profiles, processing payments, fraud prevention, analytics and product improvement, plus sharing with vaulting partners, payment protocol providers and the merchants that fulfil each order. CartAI states it neither sells personal data nor shares it for cross-context behavioural advertising.
Data retention & training
Hosting summary
CartAI states that it is established in the United States and that it and its service providers may process personal data in the United States and in other countries whose data protection laws differ, applying appropriate safeguards such as standard contractual clauses where transfers from the EEA or the UK require them. Beyond that sentence, the site names no hosting country, no region and no data residency option: hosting and infrastructure providers appear only as a category of service providers in the privacy policy, without names. There is no trust or security page and no certification is claimed by CartAI itself; the only standard cited is PCI DSS, and it is carried by the third-party vaulting partners that hold the raw card numbers. Security measures listed are encryption in transit, access controls and regular security reviews. For the record, the domain resolves to an Amazon network node in Amsterdam, but that is a content delivery point of presence and tells nothing about where the data itself lives.

Things to keep in mind
Risks and trade-offs to weigh before adopting CartAI.
- An agent holding stored payment credentials can place real orders: a badly scoped workflow or a leaked API key turns into money spent, not just data exposed
- Checkout profiles and vaulted tokens are kept by default to pre-fill future purchases on any CartAI-powered surface, and it is the integrator, not CartAI, who must obtain end-user consent for that
- Removing friction from buying also removes the pause that protects against impulse: embedding one-tap purchase into editorial or recommendation feeds shifts real responsibility onto whoever designs the surface
- CartAI is never the merchant of record, so a failed, incomplete or duplicated order leaves the customer to pursue the merchant or the card issuer, not the vendor
- Liability is capped at the greater of three months of fees or one hundred US dollars, and disputes go to individual arbitration in Texas unless opted out in writing within thirty days
- The absence of any GDPR statement, DPA or subprocessor list makes European personal data a compliance decision to take deliberately, not by default
- Pricing is invisible until you are inside the product and may be revised with reasonable notice, which makes long-term cost exposure hard to model
Setup & Integrations
Technical difficulty
Moderate, and firmly developer-oriented — there is no no-code path today. The first call is quick: create an account, generate a key, and send one POST with an X-API-Key header, all in test mode within minutes. A full integration is more demanding: payment sessions must be created server-side and rendered by redirect or iframe, a webhook endpoint has to be exposed and secured with Basic Auth or OAuth, and asynchronous task states must be handled. Going live also requires a manual review. Teams building agents can shortcut most of this with the MCP server.

Should you pick CartAI?
CartAI is a narrow tool, and says so plainly: it exists to make a transaction clear, and treats that constraint as its defensive position rather than a limitation to outgrow. That focus shows in the product. The checkout task, the catalogue endpoints, the hosted payment session and the affiliate commission all serve the same moment, and the cooperative stance towards Cloudflare, HUMAN and Fingerprint — signed identity instead of evasion — is a more durable engineering choice than most agent tooling makes.
The maturity is real but uneven. Catalog, Checkouts, Payments and Monetization are described as production capabilities and illustrated with orders the company says cleared at named retailers, while the Hosted Cart and American Express support are still announced rather than shipped. Anyone counting on the drop-in cart should confirm its status before planning around it.
Two reservations deserve weight. The first is commercial: nothing about the price is public, and the only stated basis — basis points on gross merchandise value — cannot be turned into a budget without opening an account or negotiating. The second is legal. The documentation is careful and detailed under United States law, with a thorough CCPA section, Texas governing law, mandatory arbitration and a liability cap of one hundred dollars or three months of fees. European coverage is far thinner: the word GDPR never appears, no Article 27 representative is named, and neither a data processing agreement nor a subprocessor list is published.
For a technical team building agentic commerce and comfortable with a young United States vendor, CartAI is a credible and unusually specific answer. For a buyer needing predictable pricing or European compliance evidence, the questions come first.
