VFB APIs

VFB provides access to its data through several APIs and databases. The core data infrastructure consists of Neo4j graph databases that store integrated neuroanatomical data, complemented by OWL reasoning services for advanced ontological queries and SOLR search for fast text-based queries.

User Access Options

For Regular Users (GUI Access):

• VFB Web Interface: https://v2.virtualflybrain.org/org.geppetto.frontend/geppetto - User-friendly web interface for browsing and querying VFB data

For Programmatic Access:

• VFBconnect Library: https://vfb-connect.readthedocs.io/ - Python library that provides high-level access to VFB data and queries. See also: VFB API Tutorial

For Advanced Data Access:

• Direct APIs (documented below): Low-level access to underlying databases and reasoning services

Important Notes

These API documentations describe the schemas used for data storage and basic interfaces. Most VFB queries are constructed from combined query chains that integrate multiple services (Neo4j, OWL reasoning, SOLR search) rather than single API calls. For details on how queries are orchestrated, see the VFB query chains documentation.

The APIs documented here are intended for:

• Advanced users needing direct database access
• Developers building custom tools or integrations
• Researchers requiring low-level data access for specialized analyses

For most use cases, we recommend starting with the VFBconnect library or the web interface.
