Developers & API

Push evidence in. Pull intelligence out.

Lantern ships a REST API, a GraphQL endpoint, and signed webhooks so your RMS, CMS, eDiscovery, or custom tools can ingest evidence, stream entities, query timelines, and embed the AI Investigation Assistant — without leaving your existing workflow.

REST + GraphQL

Ingest, query, and search every case asset with stable v1 endpoints and a typed GraphQL schema.

Signed webhooks

Get notified when processing finishes, when entities match watchlists, or when AI insights are ready.

RMS / CMS connectors

Pre-built integrations for Mark43, Axon, Relativity, Nuix, Cellebrite Reader, and more.

Per-environment API keys

Separate keys for dev, staging, and prod. Scope to read-only, ingest-only, or full access.

Code samples

From your terminal to a processed case — in three calls.

Ingest evidence (REST)bash

curl -X POST https://api.lantern.dev/v1/cases/CASE_ID/evidence \
  -H "Authorization: Bearer $LANTERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "source": "subpoena_return",
    "provider": "att",
    "filename": "AT&T-return-2026-03.pdf",
    "uri": "s3://your-bucket/evidence/att-return-2026-03.pdf",
    "metadata": { "warrant_id": "W-2026-0142" }
  }'

Query a case timeline (GraphQL)graphql

query CaseTimeline($caseId: ID!) {
  case(id: $caseId) {
    name
    timeline(first: 50) {
      edges {
        node {
          timestamp
          actor { id displayName }
          eventType
          summary
          sourceDocument { id filename page }
        }
      }
    }
    aiInsights {
      nextSteps
      keyEntities { name type confidence }
    }
  }
}
