Build an ONDC Dispute Triage Engine with Vercel AI SDK and OpenRouter
In light of over 5.1 lakh e-commerce complaints registered in India, public delivery networks like the Open Network for Digital Commerce (ONDC) require automated, multilingual, and policy-compliant dispute resolution systems. This challenge requires building a real-time e-commerce dispute triage engine using Vercel AI SDK and OpenRouter API, designed to process citizen complaints across multiple Indian languages, parse logistics and transaction telemetry, and generate structured resolution recommendations.
What you are building
Build an AI SDK-powered multi-lingual dispute triage pipeline utilizing OpenRouter model switching to automatically analyze ONDC e-commerce customer claims.
How work is evaluated
Evaluates the triage engine's accuracy in classifying complaint severity, extracting transaction IDs, and outputting standardized JSON schema recommendations.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
schema_validation
Output must strictly conform to required JSON schema without missing properties.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
classification_accuracy
Accuracy of grievance_category classification • target: 0.95 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
Learning goals
Implement structured output streaming using Vercel AI SDK and TypeScript.
Configure multi-model routing via OpenRouter to dynamically select LLMs based on language and complexity.
Integrate automated fraud detection and refund eligibility scoring against ONDC protocol specifications.
Validate JSON schema compliance for dispute triage outputs under strict runtime bounds.
Resources
Synthetic dataset of 500 multilingual e-commerce dispute records formatted according to ONDC payload structures, including buyer complaints in Hindi, Tamil, Telugu, and English.
Challenge setup
Evaluates the triage engine's accuracy in classifying complaint severity, extracting transaction IDs, and outputting standardized JSON schema recommendations.
