Access Synapse

One API key, four ways in — a Python SDK, a REST API, an MCP server for AI agents, and bulk Parquet exports for local analysis.

Get your API key Read the docs

Python SDK

The client library, once published. Until then the REST API and MCP server cover the same surface.

Not yet published to PyPI — use the REST API or MCP server today.

pip install synapse-discovery

from synapse_discovery import SynapseClient
client = SynapseClient("YOUR_API_KEY")
aapl = client.fundamentals("AAPL")[0]

REST API

Any language, any stack. Authenticate with an API-key header.

curl -H "X-API-Key: YOUR_API_KEY" \
  https://synapsediscovery.io/api/v1/entity/AAPL

MCP Server AI-native

Let Claude, GPT, and other agents query directly — 26 tools, responses built for LLMs.

{
  "mcpServers": {
    "synapse": {
      "url": "https://synapsediscovery.io/mcp/jsonrpc",
      "headers": { "X-API-Key": "YOUR_API_KEY" }
    }
  }
}

Bulk Parquet Quant+

Pull the universe as partitioned Parquet for local analysis — prices, fundamentals, holdings, and more.

client.bulk.download(
    dataset="prices",
    universe="sp500",
    out="./data",
)

Bulk export is included on the Quant plan and above.
