Low-Latency Payment Routing and Fraud Risk Engine with Mastra AI

Modern payment orchestrators face strict sub-100ms latency budgets while routing cross-border payments through optimal processing rails. Build an intelligent real-time payment routing and fraud risk decision engine using Mastra AI and BentoML, maintaining under 80ms P99 latency while reducing transaction failure rates by 25%.

What you are building

Deploy a high-performance microservice architecture pairing Mastra AI agent workflows with BentoML model serving to calculate real-time route quality and risk scores dynamically.

How work is evaluated

Evaluation

Evaluates P99 pipeline execution latency and optimal payment rail selection.

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

Latency SLA Test

P99 latency must remain under 80ms across 1,000 requests.

Binary check

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

Dimension 2

routing_efficiency

Cost optimization ratio relative to default routing • target: 0.25 • range: 0.15-0.5

Binary check

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

Learning goals

  • Construct Mastra AI workflow graphs for condition-based payment path evaluation

  • Serve low-latency fraud risk classifiers using BentoML model runners

  • Implement real-time fallback routing logic under network degradation constraints
