Tool Calling and Plugins for List Screening and KYC Verification

List screening data primarily comes from sanction lists published by global regulatory agencies, risk entity directories from international compliance

What the data for this category looks like

List screening data primarily comes from sanction lists published by global regulatory agencies, risk entity directories from international compliance organizations, and industry-built compliance databases. Data updates follow no fixed schedule but use high-frequency pushes. Some core lists sync in real time alongside regulatory policy changes. Data is stored in structured format, including fields such as unique entity identifier, entity type (individual/institution), core identity information, sanction/risk basis, effective date, expiration date, and more. Date fields use the ISO 8601 standard format. Identity information fields have no fixed length limit, and some fields can be empty to support undisclosed privacy protection scenarios.

What constraints these characteristics impose on tool calling and plugins

Since list data sources are scattered and update frequencies are inconsistent, tool calling must support configuration of custom data source addresses and update triggers to avoid reliance on locally fixed static list packages. Structured fields may contain null values and naming differences, so plugins must include customizable field mapping rules to adapt to field formats of different data sources. Entity information has no fixed length limit, so tool calling must configure reasonable request sharding and parsing timeout thresholds to prevent request blocking caused by long text fields. Some data must comply with privacy protection requirements, so plugins must support desensitization logic for sensitive fields to avoid unauthorized information disclosure during calls.

Configuration Settings

Configuration ItemRecommended ValueRationale
data_source_urlHTTPS interface address of the user's compliant data sourceAdapt to custom deployment and compliance requirements of list data sources
update_frequencyEvery 12 hoursMatch the update rhythm of most regulatory lists, balance real-time performance and resource consumption
field_mapping_ruleField correspondence matched through actual testingAdapt to field naming and format differences of different data sources
request_timeout30 secondsAdapt to parsing and transmission time of long list data
sensitive_field_maskID number, associated event numberComply with general requirements for compliant data desensitization
max_batch_sizeFirst 1000 entriesControl the amount of data in a single request to avoid interface overload

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis, and testing on internal samples should be completed before finalizing values.

Three Common Misconfigurations

  • API calls return empty results or do not include target list data, while the platform test interface returns results normally. The cause is failure to explicitly configure the data source identifier for list screening in API request parameters, and the corresponding plugin's data source configuration is not loaded by default.
  • Tool calls return the 413 Request Entity Too Large error. The cause is failure to configure the max_batch_size parameter, and the amount of list data passed in a single request exceeds the interface limit.
  • Desensitized results still contain unhidden sensitive fields. The cause is failure to add the corresponding field in the sensitive_field_mask configuration, or incorrect field mapping rules matching non-desensitized fields.

How to Confirm Proper Configuration

  • Access the platform's plugin debugging interface, input test entity information, trigger list screening, and verify that returned results match expected list data.
  • Include the correct plugin configuration identifier when calling the API interface, and compare API returned results with those from the platform debugging interface.
  • Review the data source update log to confirm the plugin automatically synchronizes the latest list data per the configured update_frequency cycle.
  • Inspect desensitized returned results to confirm fields configured in sensitive_field_mask have been hidden per the defined rules.
