# Hyperliquid Replica CMDs OpenAPI Schema

> Hyperliquid replica commands OpenAPI specification for the SQD Portal — endpoints and schemas for streaming HyperCore replica state, blocks, and actions.

The Hyperliquid Replica Commands OpenAPI specification for the SQD Portal is published at [https://docs.sqd.dev/files/hyperliquid-replica-cmds-openapi.yaml](https://docs.sqd.dev/files/hyperliquid-replica-cmds-openapi.yaml).

Use it to import the Portal API into OpenAPI-aware tools — code generators, API testing platforms (Postman, Bruno), or LLM-agent toolchains that consume OpenAPI to build tool definitions.

## Fetch the spec

```bash theme={"system"}
curl -O https://docs.sqd.dev/files/hyperliquid-replica-cmds-openapi.yaml
```

For the interactive, browsable version of the same endpoints, see the [Hyperliquid Replica CMDs Portal API reference](/en/api/hyperliquid-replica-cmds/metadata).
