Overview

Creates a new entity with the specified type and attributes. Entities represent the core data objects you want to analyze for risk and compliance.

Endpoint

POST http://api.gu1.ai/entities

Authentication

Requires a valid API key in the Authorization header:
Authorization: Bearer YOUR_API_KEY

Request Body

type
string
required
The type of entity to create. Available types:
  • person - Individual person/customer
  • company - Business entity
externalId
string
Your unique identifier for this entity in your system (optional but recommended for easier tracking)
name
string
required
Display name for the entity
countryCode
string
required
ISO 3166-1 alpha-2 country code (e.g., “US”, “BR”, “AR”)
taxId
string
Tax identification number (validated based on country)
email
string | null
Optional primary contact email stored on the entity row (nullable). Existing entities keep null until set. Send null on PATCH to clear.
phone
string | null
Optional primary contact phone stored on the entity row (nullable). Existing entities keep null until set. Send null on PATCH to clear.
operationalHours
object | null
Optional weekly operational hours for KYT rules (outside_entity_operational_hours). Root-level field (not inside attributes).
  • timezone (required when operationalHours is sent): must be one of the transaction_time_zone enum values. Full list: Transaction Time Zone Enum.
  • weekly: keys mondaysunday. Each day: { "start": "09:00", "end": "18:00" } or { "closed": true }. Omitted days are treated as closed.
  • Used by transaction rules that compare transactedAt to this schedule in the entity’s local timezone.
nationality
string | null
Optional root-level nationality: ISO 3166-1 alpha-2, or a recognized label the API maps to ISO2. If omitted, the root field may still be derived from entityData.person.nationality or entityData.company.nationality when mappable.
registrationDate
string | number | Date
Registration or incorporation date of the entity. Accepts:
  • ISO 8601 datetime string (e.g., “2020-06-15T00:00:00Z”)
  • Unix timestamp (number)
  • JavaScript Date object
attributes
object
Optional - Custom attributes as key-value pairs for flexible metadataUse this for custom fields that don’t fit in the standard schema (e.g., internal IDs, tags, flags)
riskFactors
object
Optional - Custom risk factors and manual risk score overridesProperties:
  • reasons (array of strings) - Reasons for the risk assessment
  • customLabel (object) - Custom risk label configuration:
    • name (string) - Label name (e.g., “High Risk”, “Suspicious”)
    • color (string) - Color code for UI display
    • status (string) - Status indicator
    • minScore (number) - Minimum score for this label
    • maxScore (number | null) - Maximum score (null for infinite)
    • severity (enum) - Severity level: ‘low’, ‘medium’, ‘high’, ‘critical’
  • displayRange (object) - Score range display configuration:
    • max (number | null) - Maximum value (null for infinite)
    • min (number) - Minimum value
    • current (number) - Current score value
    • isInfinite (boolean) - Whether the range is infinite
  • originalScore (number) - Original calculated score before manual override
  • normalizedScore (number) - Normalized score value
Use case: Override automatic risk scoring with manual assessments for special cases.
entityData
object
Optional - Type-specific data structure. See examples below for each entity type.
When to use entityData?
  • Optional for basic entity creation - You can create an entity with just type, name, taxId, and countryCode
  • Required for enrichment and risk analysis - If you want to run compliance checks, you’ll need to provide relevant fields
  • Can be populated later - You can create a minimal entity first, then update it with full data before running risk analysis
Minimal Example (Person):
{
  "type": "person",
  "name": "John Doe",
  "taxId": "12345678",
  "countryCode": "US"
  // No entityData needed for basic creation
}
Full Example (Person with KYC data):
{
  "type": "person",
  "name": "John Doe",
  "taxId": "12345678",
  "countryCode": "US",
  "entityData": {
    "person": {
      "firstName": "John",
      "lastName": "Doe",
      "dateOfBirth": "1980-01-15",
      "email": "john@example.com",
      "phone": "+1234567890"
    }
  }
}
isClient
boolean
default:"false"
Mark this entity as a client/customer for tracking purposes
riskMatrixId
string | string[]
One or more risk matrix UUIDs (legacy: a single UUID string). If provided, after creation the system evaluates this entity only against active rules tied to those matrices (unless skipRulesExecution is true). Same semantics as riskMatrixIds when you send a single id as a string.
riskMatrixIds
string[]
Preferred way to pass multiple matrices: ordered list of UUIDs belonging to your organization. When present and non-empty, it takes precedence over riskMatrixId.
skipRulesExecution
boolean
default:"false"
Skip automatic rules execution after entity creation
shareholderDepth
number
default:"0"
For company entities: How many levels of shareholders to auto-create (0-5).
  • 0 = None (default)
  • 1 = Direct shareholders only
  • 2 = Shareholders + their shareholders
  • 3-5 = Deeper nested levels
Useful for automatic KYB and UBO (Ultimate Beneficial Owner) discovery.
status
string
default:"under_review"
Initial status for the entity. Options:
  • active - Entity is active
  • inactive - Entity is inactive
  • blocked - Entity is blocked
  • under_review - Entity is under review (default)
  • suspended - Entity is suspended
  • expired - Entity has expired
  • deleted - Soft deleted
  • rejected - Entity was rejected
monitoring
object
Optional. Requests watchlist mode (op 1: screening plus watchlist subscription for periodic runs) for a monitoring-capable enrichment, instead of a one-off check (op 0).Scope today: only global_gueno_sanctions_enrichment. Map keys must match codes in autoExecuteIntegrations.enrichments. Legacy *_check codes were removed (2026-06-04) and are no longer part of the contract.
  • main: flags for the main entity on this POST /entities.
  • relationships: ignored here; use Create automatically with depth > 0.
Per-code value (object recommended; legacy boolean still accepted):
  • { "watchlist": true } — subscribe; monitoring rules use the entity’s global riskMatrixId.
  • { "watchlist": true, "riskMatrixId": "<uuid>" } — subscribe; only that matrix on monitoring-triggered runs.
  • { "watchlist": false } or false — no watchlist.
  • true — same as { "watchlist": true }.
Requirements (if any fail, enrichment still runs as op 0): (1) code in enrichments or active via execute-all; (2) org monitoring ON in Marketplace for Gu1 sanctions.Guide: Gu1 sanctions monitoring. Examples: Monitoring on create.
autoExecuteIntegrations
object
Configure automatic execution of enrichment integrations when creating the entity.Properties:
  • executeAllActiveEnrichments (boolean) - Execute all active enrichment integrations
  • enrichments (array) - Array of specific enrichment provider codes to execute (see Provider Codes Reference)
  • enrichmentGroupRefs (array of strings, optional) - Marketplace enrichment group slugs. With executeAllActiveEnrichments: false, groups are resolved and merged with explicit enrichments. With executeAllActiveEnrichments: true, group refs are ignored (not resolved); explicit enrichments may still append after the active set.
  • excludeEnrichments (array, optional, default: []) - Provider codes to omit from the final resolved enrichment set

Query Parameters

refresh
boolean
default:"false"
Force re-enrichment of the entity even if it already exists in the system.Type: boolean (query string: "true" or "false")Behavior:
  • When true: Forces the system to fetch fresh data from enrichment providers (e.g., background checks, KYC data, company registries)
  • When false or omitted: Uses cached enrichment data if available
  • Overrides organization setting enrichmentsConfig.reEnrichExistingEntities
Use Cases:
  • Re-validating entity data after a significant time period
  • Updating information when you know external data has changed
  • Manual refresh triggered by compliance team
  • Periodic data quality audits
Example:
POST http://api.gu1.ai/entities?refresh=true
Note: Re-enrichment may incur additional costs from third-party data providers.

Response

success
boolean
Indicates if the entity was created successfully
entity
object
The created entity object including:
  • id - gu1’s internal ID
  • externalId - Your external ID
  • organizationId - Your organization ID
  • type - Entity type
  • name - Entity name
  • riskScore - Initial risk score (0-100)
  • status - Entity status
  • entityData - Type-specific data
  • attributes - Custom attributes
  • createdAt - Creation timestamp
  • updatedAt - Last update timestamp
rulesResult
object
Result of rules execution (only present when rules ran, e.g. when skipRulesExecution is false and a risk matrix is configured), including:
  • success (boolean) - Whether rules executed successfully
  • rulesTriggered (number) - Number of rules that were triggered
  • alerts (array) - Alerts generated by rules
  • riskScore (number) - Final calculated risk score
  • decision (string) - Final decision (APPROVE, REJECT, HOLD, REVIEW_REQUIRED)
  • rulesExecutionSummary (object) - Present when rules ran. See below for structure.
rulesExecutionSummary
object
At the root of the response (same as transactions API). Only present when rules ran (e.g. skipRulesExecution is false and rules engine executed). Same value as rulesResult.rulesExecutionSummary. Summary of which rules matched (hit) vs did not match (no hit), executed actions, and total score. Omitted when rules did not run.
  • rulesHit (array) - Rules whose conditions were met. Each item: name, description, score, priority, category, status (e.g. active, shadow), conditions (array of { field, value, operator? }), actions (alerts, suggestion, status, assignedUser).
  • rulesNoHit (array) - Rules that were evaluated but conditions were not met. Same structure as rulesHit (includes configured actions, not executed).
  • actionsExecuted (object) - Aggregated executed actions across all rules that hit: alerts (array of { name?, type?, severity?, description? }), suggestion (BLOCK | SUSPEND | FLAG, highest weight), status (entity status applied, if any), assignedUser ({ userId }, if any), customKeys (array of strings, optional) — custom action keys from matched rules; for integrations/workflows.
  • totalScore (number) - Sum of score of all rules that hit and are not in shadow status.

Example: Gu1 sanctions monitoring on create

monitoring does not run integrations by itself — it only changes how an enrichment already listed in autoExecuteIntegrations runs. Today the documented case is global_gueno_sanctions_enrichment (org must allow monitoring in Marketplace).
ConditionEffect
Code in enrichments + monitoring.main[code] with watchlist on + org monitoring ONOp 1 — screening plus watchlist / daily screening.
No monitoring or watchlist: falseOp 0 — one-off screening only.
monitoring set but org monitoring OFFOp 0 — no mandatory error; screening still runs.
monitoring without the code in enrichmentsNo effect.
Legacy *_check codes (e.g. global_gueno_sanctions_check) were removed (2026-06-04). For watchlist on create, use global_gueno_sanctions_enrichment in both enrichments and monitoring.main.

Watchlist only (person)

{
  "type": "person",
  "externalId": "cust_screening_001",
  "name": "María González",
  "countryCode": "AR",
  "taxId": "27-12345678-1",
  "entityData": {
    "person": {
      "firstName": "María",
      "lastName": "González",
      "dateOfBirth": "1985-03-15",
      "nationality": "AR"
    }
  },
  "monitoring": {
    "main": {
      "global_gueno_sanctions_enrichment": {
        "watchlist": true
      }
    }
  },
  "autoExecuteIntegrations": {
    "executeAllActiveEnrichments": false,
    "enrichments": ["global_gueno_sanctions_enrichment"]
  }
}

Local enrichments + Gu1 monitoring (AR person)

Combine registry/KYC enrichments with Gu1 watchlist in one POST /entities. monitoring only affects keys present in the map.
{
  "type": "person",
  "name": "María González",
  "taxId": "20-12345678-9",
  "countryCode": "AR",
  "riskMatrixId": "550e8400-e29b-41d4-a716-446655440000",
  "entityData": {
    "person": {
      "firstName": "María",
      "lastName": "González",
      "dateOfBirth": "1985-03-15"
    }
  },
  "autoExecuteIntegrations": {
    "executeAllActiveEnrichments": false,
    "enrichments": [
      "ar_renaper_data_enrichment",
      "ar_repet_person_enrichment",
      "global_gueno_sanctions_enrichment"
    ]
  },
  "monitoring": {
    "main": {
      "global_gueno_sanctions_enrichment": {
        "watchlist": true
      }
    }
  }
}
ar_renaper_* and ar_repet_* run as normal enrichments; only global_gueno_sanctions_enrichment can use op 1 when org monitoring is enabled.

Dedicated risk matrix for monitoring (optional)

"monitoring": {
  "main": {
    "global_gueno_sanctions_enrichment": {
      "watchlist": true,
      "riskMatrixId": "660e8400-e29b-41d4-a716-446655440001"
    }
  }
}
riskMatrixId: null means inherit the entity global matrix for monitoring runs.

Company (type: "company")

Same monitoring.main shape; adjust type, entityData.company, and enrichments for your country.
{
  "type": "company",
  "externalId": "co_screening_001",
  "name": "Tech Solutions S.A.",
  "countryCode": "AR",
  "taxId": "30-71000001-2",
  "entityData": {
    "company": {
      "legalName": "Tech Solutions S.A.",
      "tradeName": "Tech Solutions",
      "industry": "Software"
    }
  },
  "monitoring": {
    "main": {
      "global_gueno_sanctions_enrichment": { "watchlist": true }
    }
  },
  "autoExecuteIntegrations": {
    "executeAllActiveEnrichments": false,
    "enrichments": ["global_gueno_sanctions_enrichment"]
  }
}
monitoring.relationships is not used on POST /entities. For shareholders or related entities in the same job, use Create automatically with depth > 0, monitoring.relationships, and matching codes in autoExecuteIntegrationsShareholders.
