ArangoDB REST API
ArangoDB REST API enables agents to perform document, graph, and key-value operations against a multi-model database using AQL (ArangoDB Query Language) over HTTP.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS configurable but not enforced by default in self-hosted deployments. Per-database and per-collection ACLs provide reasonable granularity. JWT secret must be kept secure on the server side. ArangoGraph cloud enforces TLS and manages certificates.
⚡ Reliability
Best When
An agent needs to combine graph traversal, document storage, and key-value access in a single query without managing multiple databases.
Avoid When
The workload is exclusively relational or exclusively time-series and benefits from a purpose-built engine.
Use Cases
- • Traverse and query complex relationship graphs such as social networks, knowledge graphs, or supply chains
- • Store and retrieve heterogeneous JSON documents with flexible schema across multiple collections
- • Execute AQL queries combining document lookup, graph traversal, and aggregation in a single request
- • Manage knowledge graphs for RAG pipelines where entities and their relationships must be stored together
- • Perform key-value lookups with sub-millisecond latency alongside richer document queries in the same database
Not For
- • Pure time-series workloads where a dedicated TSDB (TimescaleDB, QuestDB) would be more efficient
- • Strict relational data with complex multi-table joins that benefit from a mature RDBMS optimizer
- • High-throughput write-heavy workloads requiring Cassandra- or ScyllaDB-class horizontal write scaling
Interface
Authentication
JWT tokens are obtained via /_open/auth endpoint using username/password. Tokens expire (configurable TTL). Database-level and collection-level permissions can be granted per user. Basic auth also supported but discouraged in production.
Pricing
Community Edition is fully open-source (Apache 2). Enterprise features require a commercial license. ArangoGraph cloud billing is consumption-based.
Agent Metadata
Known Gotchas
- ⚠ AQL cursor results expire after a configurable TTL (default 30s); agents must consume or explicitly delete cursors to avoid resource leaks
- ⚠ Multi-document transactions require explicit BEGIN/COMMIT; forgetting to commit leaves locks that block other operations
- ⚠ Graph traversal depth is bounded by default (maxDepth); agents querying unbounded graphs may silently get incomplete results without error
- ⚠ JWT tokens have a default 1-hour expiry; long-running agent sessions must refresh tokens proactively or handle 401 errors
- ⚠ Collection type (document vs edge) must be declared at creation time and cannot be changed; agents creating collections dynamically must track this distinction
