  prompt={`Look up which fraud networks an entity belongs to through the Management API.

Authentication:
Use the x-api-key header with my Didit API key on every call.

Endpoints (all GET, all return {"results": [EntityNetworkMembership, ...]}, not paginated):
- /v3/organization/{organization_id}/application/{application_id}/sessions/{session_id}/networks/ - resolves through the session's linked vendor user.
- /v3/organization/{organization_id}/application/{application_id}/business-sessions/{business_session_id}/networks/ - resolves through the business session's linked vendor business.
- /v3/organization/{organization_id}/application/{application_id}/users/{vendor_user_uuid}/networks/
- /v3/organization/{organization_id}/application/{application_id}/businesses/{vendor_business_uuid}/networks/
- /v3/organization/{organization_id}/application/{application_id}/transactions/{transaction_uuid}/networks/ - resolves through the transaction's backing KYC/KYB session's subject.
- /v3/organization/{organization_id}/application/{application_id}/transactions/{transaction_uuid}/parties/{transaction_party_uuid}/networks/ - resolves through the party itself (remitter, beneficiary, or counterparty), independent of the backing session.

Example call:
curl -X GET "https://verification.didit.me/v3/organization/{organization_id}/application/{application_id}/users/{vendor_user_uuid}/networks/" \\
-H "x-api-key: YOUR_API_KEY"

Response shape:
Each EntityNetworkMembership has network (NetworkListItem), subject, signal_types, signal_count, joined_at, last_seen_at.
An entity can belong to zero, one, or several networks - an empty results array is not an error.

Failure modes:
- 404 - the session/business session/user/business/transaction/transaction party does not exist in this application, or (for the session and transaction variants) has no linked vendor user/business to look up.
- 401/403 - auth/permission errors.

Side effects: none, pure read.

For the full integration shape, see /integration/integration-prompt.`}
/>

Given a session, business session, user, business, transaction, or transaction party, look up which fraud networks it belongs to. Every variant returns the same shape - `{"results": [EntityNetworkMembership, ...]}` - so you can point any entity you already have a UUID for at the matching endpoint without a separate lookup step.

| Entity            | Endpoint                                                                             | Resolves through                                          |
| ----------------- | ------------------------------------------------------------------------------------ | --------------------------------------------------------- |
| Session           | `GET .../sessions/{session_id}/networks/`                                            | The session's linked vendor user                          |
| Business session  | `GET .../business-sessions/{business_session_id}/networks/`                          | The business session's linked vendor business             |
| User              | `GET .../users/{vendor_user_uuid}/networks/`                                         | The vendor user directly                                  |
| Business          | `GET .../businesses/{vendor_business_uuid}/networks/`                                | The vendor business directly                              |
| Transaction       | `GET .../transactions/{transaction_uuid}/networks/`                                  | The transaction's backing KYC/KYB session's subject       |
| Transaction party | `GET .../transactions/{transaction_uuid}/parties/{transaction_party_uuid}/networks/` | The party itself (remitter, beneficiary, or counterparty) |

Each `EntityNetworkMembership` carries the network summary (`network`, same shape as [list networks](/management-api/networks/list)), the resolved `subject`, which `signal_types` connected it, `signal_count`, and `joined_at`/`last_seen_at`. An entity with no fraud connections returns an empty `results` array, not a 404.

<Note>
  The transaction endpoint resolves membership through the transaction's backing session's subject. The transaction party endpoint resolves it through the party itself, which is what you want for a remitter or beneficiary that is not the transaction's own KYC subject.
