High-Speed ISO 20022 Pacs.008 Payment Payload Repair & Routing System

In high-throughput interbank payment networks, even tiny syntactic errors in incoming ISO 20022 `pacs.008` messages (such as missing BIC codes, malformed IBANs, or corrupted postal strings) cause straight-through processing (STP) failures, forcing manual queue repair. In this challenge, you will implement an automated payment payload repair agent using CrewAI. The multi-agent swarm will collaborate to validate message fields, repair BICs via lookup registries, reformat malformed clearing tags, and re-inject validated ISO 20022 XML messages back into the STP rail.

Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Develop a multi-agent ISO 20022 message repair swarm using CrewAI to restore high Straight-Through Processing (STP) rates.

Delivery guide

How work is evaluated

Evaluation

Evaluates message repair accuracy and final ISO 20022 XML schema validity.

Datasets

Challenge datasets

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

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

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

xml_well_formed

Verifies output is well-formed XML and contains valid BIC code format

Binary check

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

Dimension 2

stp_repair_success_rate

Percentage of corrupted payloads successfully converted to valid STP state • target: 96 • range: 0-100

Binary check

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

Learning goals

What you should walk away with

  • Configure specialized CrewAI agents (`xml_parser_agent`, `bic_lookup_agent`, `stp_validator_agent`)

  • Build custom BIC and IBAN lookup tools to repair missing ISO 20022 header elements

  • Maintain high Straight-Through Processing (STP) execution speeds without corrupting message payloads

  • Output valid, schema-compliant `pacs.008` XML strings
