SDKs & Languages¶

Meridian ships SDKs in six languages. Pick the one your team knows — the kernel API is identical across all of them.

Available SDKs¶

Language	Status	Install	GitHub
Python	Production-ready (84 operations)	`pip install open-meridian`	meridian-python
Go	Production-ready (84 operations)	`go get github.com/Societal-Lab-Inc/meridian-go`	meridian-go
TypeScript	Production-ready (84 operations)	`npm install open-meridian`	meridian-typescript
Java	In development	Coming soon	meridian-java
C++	In development	Coming soon	meridian-cpp
Rust	In development	Coming soon	meridian-rust

All six SDKs implement the same 84 kernel API operations across OMS, EMS, and BOR surfaces. Code written against any SDK works identically in local and deployed environments.

Development Modes¶

Mode	Infrastructure	Best For
Local	None — everything in-process	Strategy development, backtesting, unit testing
Connected	Sidecar + bus + kernel	Coming soon

Local mode is where most development happens. No Docker, no sidecar, no message bus — just your code and the SDK. When you're ready to deploy, the same plugin binary connects to a live sidecar with zero code changes.

Getting Started¶

Python¶

pip install open-meridian

from meridian import LocalClient

client = LocalClient()
# You now have access to all 84 kernel operations

Full documentation and examples: meridian-python

Go¶

go get github.com/Societal-Lab-Inc/meridian-go

import meridian "github.com/Societal-Lab-Inc/meridian-go"

client := meridian.NewLocalClient()
// You now have access to all 84 kernel operations

Full documentation and examples: meridian-go

TypeScript¶

npm install open-meridian

import { LocalClient, SignalEngine, type DataWindow } from "open-meridian";

const client = new LocalClient({ startingCash: 100_000 });
client.loadBars("BTC", "data/btc-usd.csv");
// You now have access to all 84 kernel operations

Full documentation and crypto examples: meridian-typescript

Data Query API¶

Query any canonical field for any instrument:

Python¶

from meridian.fields import CLOSE, DURATION, GICS_SECTOR

price = client.data.get("AAPL", CLOSE)           # from loaded bars
sector = client.data.get("AAPL", GICS_SECTOR)    # None in local mode, resolved in connected mode

Go¶

price, _ := client.Data().Get("AAPL", meridian.FieldClose)
sector, _ := client.Data().Get("AAPL", meridian.FieldGICSSector)

The SDK ships 62 canonical field constants covering identifiers, prices, reference data, fixed income, derivatives, fundamentals, and compliance. Use these instead of string literals — they're the same field names across all SDKs, all DGM plugins, and all data queries.

In local mode, OHLCV fields resolve from loaded bar data. All other fields return None/nil — they'll resolve automatically when connected to a live deployment with DGM and analytics plugins.

API Reference Documentation

Full API reference for each SDK is published separately — Python API Docs and Go API Docs (coming soon). The SDK repositories contain comprehensive usage guides, code samples, and per-method documentation.
