Building on Nexyron

Nexyron is usable directly, not only through its own interface. Everything below runs against the same connected model, so an answer is the same answer whichever way you arrive at it.

Choosing an interface

Cypher, over HTTP or WebSocket. The primary way to ask anything. Cypher is a graph query language: you describe a pattern of subjects and relationships and get back rows. Nexyron extends it with procedures for graph algorithms, history over time, semantic search and model scoring, which means analysis that would otherwise need a separate pipeline stays inside one query.

Start with the Cypher reference.

Embedded, inside your own process. When the application and the data belong together and a network hop is not wanted, Nexyron runs in-process through a language binding. See language bindings.

Through an AI assistant. Nexyron connects to assistants such as Claude, Codex and ChatGPT desktop, which can then work against your business model directly. See AI assistants.

Bolt. For tooling that already speaks the Bolt protocol.

Two things worth knowing early

Cypher here is its own dialect. Nexyron is not a drop-in replacement for another graph database. Queries carried over from elsewhere will generally not run unchanged, and that is deliberate rather than an oversight.

The dialect is documented in full, and when a query fails Nexyron does not just reject it: the error explains what is wrong, names the closest thing that does exist, points at the reference page for it, and gives a runnable example. In practice this is faster to work with than compatibility would have been, because the guidance is specific to what you were trying to do.

Validate before you run. Any query can be checked without executing it. It returns whether the query is valid and what is wrong if not, while reading nothing and writing nothing. It is the cheapest step in the loop and worth making a habit, particularly when a query is being generated rather than typed.

A first query

MATCH (c:Customer)-[:BELONGS_TO]->(s:Site)
RETURN s.name AS site, count(c) AS customers
ORDER BY customers DESC
LIMIT 10

From there, the Cypher reference covers every clause, function, procedure and algorithm, each with runnable examples.
