Build on Kuudo
Amazon API Integration for Your SaaS Product
Amazon API integration is the part of your product nobody buys it for. Build on Kuudo and you skip it: no separate Amazon Ads, Seller Central and Vendor Central integrations to build, and none to maintain as Amazon changes them. Your software calls Kuudo, and you ship the features your customers pay for.
Kuudo does not ship client software. Claude is a client. ChatGPT is a client. Your product is a client, and it connects the same way they do.
| Your feature | Your product asks Kuudo for | Kind |
|---|---|---|
| Profit dashboard | Orders, fees and ad spend | Read |
| Inventory planner | Stock levels and inbound shipments | Read |
| Vendor reporting | Purchase orders and retail analytics | Read |
| Bid automation | A budget or bid change | Write, on your policy |

Three Amazon integrations you no longer build.
A team on Amazon plumbing
Amazon Ads, Seller Central and Vendor Central are separate APIs with separate approvals, sign-in flows, rate limits and release schedules. Your engineers build all three, then keep rebuilding them as Amazon changes each one.
One Amazon layer, kept current
- Amazon Ads
- Seller Central
- Vendor Central
- Amazon Marketing Cloud
Your product connects to Kuudo. Kuudo carries the Amazon side and keeps it current, so your roadmap goes to the product.
What comes off your roadmap:
1,139 Amazon operations are already there: 756 for Amazon Ads, 341 for Seller Central and 42 for Vendor Central. See the full tool reference.
Your customers authorize their own Amazon accounts through Kuudo. On Pro and Scale they consent to Kuudo's managed Amazon app, so you do not register an Amazon app of your own.
When Amazon adds an API, retires a report or changes a field, the change lands in Kuudo. Your product keeps calling the same tools.
Your product is the client.
Kuudo speaks the Model Context Protocol (MCP), the open standard AI clients use to call tools. Anything that speaks it can connect, and that includes the software you sell.
- 1 Your customer authorizes
Your customer approves access to their Amazon account, or you send them an invitation link. Nobody shares a login.
- 2 Your product connects
Your product connects to Kuudo's endpoints as a client and sees the Amazon tools that customer has authorized. Amazon Ads has one endpoint; Seller Central and Vendor Central share another.
- 3 Kuudo calls Amazon
Reads return data to your product. Writes follow the policy you set and can wait for a person to approve them.
- 4 You ship the feature
The dashboard, the alert, the recommendation or the agent your customer sees is yours. Kuudo stays underneath it.
The whole Amazon job, behind your product.
Ads, seller and vendor from one provider
Amazon Ads, Amazon Marketing Cloud, Seller Central and Vendor Central connect the same way, with the same sign-in and the same tool format. A feature that combines ad spend with seller orders uses two Kuudo endpoints, not two Amazon integrations built from scratch.
Managed, or in your own cloud
Start on Managed MCP, where Kuudo runs the servers. Choose Private Cloud when your customers' data has to stay in infrastructure you control. You can move between them.
Priced by API call
You pay for the Amazon calls your product makes, so cost follows usage as your customer base grows. Products with many customer accounts fit the Enterprise plan; bring your numbers and we will size it with you.
Ready for the AI you add next
The connection your backend uses is the one AI models use. When you add an assistant or an agent to your product, it calls the same Amazon tools, and Kuudo's Skills and Amazon operating knowledge are there for it to use.
Four products, one Amazon layer.
These are illustrations of what software companies build on Kuudo, not customer names.
A profit and reporting product
Pulls orders, fees, returns and ad spend for each customer account and turns them into the margin view your product is known for.
An inventory planner
Reads stock, inbound shipments and sales velocity, then warns your customer before a stockout and drafts the replenishment plan.
A bid and budget tool
Reads campaign performance, proposes bid and budget changes by your rules, and submits the ones your customer approves.
An assistant for sellers
Your own AI assistant, inside your app, that answers questions from the customer's live Amazon account and takes the actions you allow.
Your product, your customers, your logic.
Your customers see your product
Your interface, your features and your name are what your customer uses every day. Kuudo is the layer underneath.
Your rules decide what happens
The thresholds, models and workflows that make your product different stay in your product. Kuudo runs the Amazon call you ask for.
Writes wait on your policy
Reads return data. Changes to a customer's Amazon account follow the policy you set, and every call is on the record.
