API Access

Full Cypher access. Any query. Any depth.

Send any Cypher query against the Whisper graph and get structured JSON back in single-digit milliseconds. Parameterized inputs, full schema introspection, and built-in procedures for time-travel and threat scoring — everything you need to build infrastructure intelligence into your own code.

When to use the API

Build custom enrichment pipelines, automate investigations, pipe infrastructure intelligence into a SIEM or data warehouse, or wire Whisper into your own application. The API is the right call any time you need full Cypher in your own code — no proxy, no SDK, no shortcuts on the schema.

Three steps to your first query

No SDK install, no client setup. Authentication is a bearer token.

Get an API key

Send Cypher over HTTPS

POST your query (with parameters) to /api/query. Standard JSON body. Any HTTP client works — curl, Python requests, Node fetch, Go, Rust.

Use the structured response

Get back columns, rows, and execution stats. Pipe to your SIEM, feed an LLM, store in a warehouse, or render in your own UI.

A real query

Send Cypher. Get JSON.

Below is a real, verified hosting-chain traversal against the live graph. Multi-hop pattern matching, structured JSON response, 2ms server-side.

Best practices

Built-in procedures

Whisper-specific superpowers on top of standard Cypher.

whisper.history() for time-travel queries
CALL explain() for threat scoring with evidence
CALL db.schema() for introspection

The Whisper Console lets you explore the graph interactively — search domains, run queries with syntax highlighting, visualize relationships, and export results. Same data, visual experience.
