# Get Dataset Lineage

> Retrieve the full lineage graph for a dataset, including upstream sources and downstream consumers.

Returns the complete lineage graph for a dataset attestation. The graph represents the provenance chain as a directed acyclic graph (DAG) of dataset and model references connected by transformation relationships.

Use dataset lineage to audit data provenance, verify that training data sources are trusted, and trace how raw data flows through preprocessing pipelines into model training.

### Authentication

<ParamField header="X-API-Key" type="string" required>
  API key with `datasets:read` scope. Alternatively, pass a Bearer JWT token in
  the `Authorization` header.
</ParamField>

<ParamField header="X-Tenant-ID" type="string" required>
  Tenant identifier for multi-tenant isolation.
</ParamField>

### Path Parameters

<ParamField path="id" type="string" required>
  Dataset attestation identifier (`maip-ds:ULID`).
</ParamField>

### Response

<ResponseField name="dataset_id" type="string">
  The root dataset identifier for this lineage query.
</ResponseField>

<ResponseField name="nodes" type="array">
  Array of lineage nodes. Each node contains: - `id` (string) -- Resource
  identifier (`maip-ds:...` or `maip-model:...`) - `type` (string) -- Node type:
  `dataset` or `model` - `name` (string) -- Human-readable name - `version`
  (string) -- Resource version - `status` (string) -- Current attestation status

  * `created_at` (string) -- ISO 8601 timestamp
</ResponseField>

<ResponseField name="edges" type="array">
  Array of transformation relationships connecting nodes. Each edge contains: -
  `source` (string) -- Source node identifier - `target` (string) -- Target node
  identifier - `relationship` (string) -- Transformation type (e.g.
  `derived_from`, `trained_on`, `preprocessed_from`, `merged_from`) - `metadata`
  (object) -- Optional edge metadata (e.g. transformation parameters)
</ResponseField>


## OpenAPI

openapi: 3.0.3
info:
  title: Truthlocks API
  description: >
    Truthlocks is a universal verification infrastructure for documents,
    credentials, and digital assets.

    This specification defines the canonical API for interacting with Truthlocks
    services.


    ## Base URLs

    - **Production**: `https://api.truthlocks.com`

    - **Sandbox**: `https://sandbox-api.truthlocks.com`


    ## Authentication

    - **API Keys**: Use `X-API-Key` header for machine-to-machine operations

    - **Bearer Tokens**: Use `Authorization: Bearer <jwt>` for user-initiated
    operations


    ## Tenant Identity

    In production, tenant identity is derived from the authenticated context
    (API key or JWT).

    The `X-Tenant-ID` header is ignored in production to prevent spoofing.
