Chaiz Partner API

Search, compare, and sell vehicle service contracts (VSCs, also called extended warranties) from a network of warranty administrators. Returns real-time quotes with pricing, coverage detail, provider ratings, and ready-to-use checkout links.

New here? This reference documents every endpoint. To work out which ones you need, read Choose Your Integration first: there are three integration paths and it takes one page to pick yours.

• Quickstart gets you a live quote and a working checkout link in about ten minutes.
• Plan Search Reference covers vehicle identification, filters, and response shapes.
• Errors and Rate Limits covers the error envelope and retry behavior.

Things to know before you start

• Authentication: every endpoint except registration needs Authorization: Bearer <your-key>. Your partner identity is inside the token, so leave the optional partner field out of request bodies.
• Latency: synchronous plan searches take 2 to 8 seconds because Chaiz is collecting live rates from multiple administrators. Use a timeout of at least 30 seconds and never retry a slow search; a retry quotes the vehicle twice.
• Response envelope: responses are wrapped as { response, errorResponse }. Check errorResponse before reading response.
• Result validity: a searchResultPlanId is valid for 30 days, after which handoff URLs stop working and you need a fresh search.
• Environments: keys are issued per environment and are not interchangeable.
• Discovery: /.well-known/chaiz-api.json is the machine-readable API manifest.
