Chaiz Partner API

Chaiz is a marketplace for vehicle service contracts (VSCs, also called extended car warranties). Our Partner API lets you offer VSCs to your customers as an upsell or cross-sell in their purchasing journey. A VSC covers parts and labor for mechanical breakdowns. As with insurance, there are many providers (you may know them as administrators) with many plans, which results in a complex matrix of coverage, benefits, payment options, and ultimately fit for the customer.

We designed the API to abstract all of that for you and your customer, so you can be up and running quickly while keeping detailed control over which quotes you get back when you need it.

Depending on your integration path, you can have a working integration on UAT in less than a day. All we need is the customer's vehicle, current mileage, and home state. The API returns live rates from a network of vetted providers, scored, ranked, and ready to present so your customer can compare and buy in a few clicks.

What you get

One endpoint. POST /api/v2/Partners/PlansSearch returns the plans, prices, ratings, and checkout links. All you need to make a sale.
Batteries included. We are the merchant of record and handle payments, PCI compliance, quote matching, contracts, and customer communications.
Reliability. The same response envelope on every call. Errors carry a code that does not change and, where we can, a suggestion for what to do about it.
Parity. UAT runs the same code as production. Test your flow, handoff, and attribution there; only postbacks wait for production. Once we have signed off your implementation, we issue your production key. See Going Live.
Transparency. Attribution works the way affiliate tracking usually does. You put your parameters on the link, we ping them to a URL of your choosing on every sale, together with our order id. We do not rename or enrich anything. More on attribution.
AI readiness. Download the OpenAPI document, or connect our MCP server to your assistant and run live plan searches before you write a line of code.

What you need to get started

An API key. Register yourself in two minutes to try things out, or email dev-support@chaiz.com to get set up with your branding, the plans to show, attribution, and higher rate limits. More in Authentication. Production keys are issued after we sign off your implementation.
A vehicle identifier. A VIN is best, then a license plate, then make, model, and year.
The customer's state and current mileage. Prices depend on both.
