# Raw markets. Canonical facts.

Meridian provides normalized crypto futures, spot, and custom trade-bar data through a stable, DataFrame-ready contract. Developers connect through Context Protocol using its TypeScript SDK, Python SDK, or official remote MCP endpoint.

<Note>
  Meridian returns stored facts. Missing or venue-limited values remain explicit through coverage metadata, provenance, warnings, and nulls. They are never silently converted to zero.

## Integration boundary

The public integration layer is Context Protocol. The underlying Meridian HTTP routes define the data contract, while the marketplace tools provide authenticated discovery, billing, execution, and MCP access.

Meridian provides market data only. It does not place orders, approve trades, manage capital, or expose trading-bot behavior.
