REST API. Send year, make, model, mileage, and DTC codes. Get back ranked causes, cost ranges, and a customer-ready summary. Designed for automotive SaaS, fleet management platforms, dealership tools, and parts marketplaces.
Authentication via API key. JSON request, JSON response. Average response time under 30 seconds. Soon: streaming responses, batch endpoint, webhook delivery.
Causes ranked specifically for the vehicle and mileage. References real TSBs and engine-specific failure patterns.
Top cause is usually right but you also get plausible alternatives with their probability. Useful for "don't replace until you verify" workflows.
Every cause description ends with a specific verification test and target value (volts, ohms, PSI, ratios). Mechanics get a structured next step.
Part cost range, labor cost range, and DIY difficulty per cause. Backed by Mitchell flat-rate data and real shop reports.
Every response includes a customer_message field, a 3-4 sentence text the end user can text or email their mechanic.
Send multiple related codes, the engine diagnoses the most likely root cause rather than treating each code independently.
Free trial with 100 calls. After that, per-call pricing with volume discounts. Enterprise contracts available with custom SLAs.
