Build Real-Time Catalog Sync Agents with AI SDK and Blaxel

Rapidly synchronizing inventory across decentralized ONDC seller nodes often results in race conditions and duplicate catalog updates. Build a serverless TypeScript routing workflow using Vercel AI SDK and Blaxel serverless agent runtimes to resolve catalog collisions instantly. Maintain less than 200ms end-to-end sync latency.

What you are building

Construct high-speed edge AI agents using TypeScript, Vercel AI SDK, and Blaxel to maintain real-time ONDC catalog synchronicity.

How work is evaluated

Evaluation

Measures catalog conflict resolution latency and accuracy under high update throughput.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

conflict_accuracy

Ensures latest timestamp record is preserved accurately

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

latency_ms

End-to-end execution latency in milliseconds • target: 200 • range: 0-500

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Implement stream generation and function calling using Vercel AI SDK in TypeScript

  • Deploy agent functions to low-latency serverless runtimes using Blaxel

  • Handle incoming high-frequency ONDC protocol catalog mutations without loss

  • Optimize agent context windows for continuous streaming response evaluation

Resources

Dataset notes

Synthetic time-stamped inventory mutations mimicking high-volume quick-commerce sales events.

Challenge setup
