# EVM OpenAPI Schema

> Use the SQD Portal EVM OpenAPI spec for blocks, transactions, logs, traces, and state.

The EVM OpenAPI specification for the SQD Portal is published at [https://docs.sqd.dev/en/api/catalog/evm/openapi.yaml](https://docs.sqd.dev/en/api/catalog/evm/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/en/api/catalog/evm/openapi.yaml
```

For the interactive, browsable version of the same endpoints, see the [EVM Portal API reference](/en/api/evm/introduction).
