RPCs - OpenAPI reference¶
OpenAPI is a specification format for REST APIs. This format is supported by several tools, such as Swagger UI which allows you to browse a specification and perform API calls from your browser. Several code generators also exist to generate API libraries for various programming languages.
The REST API served by the Octez node on the RPC port is described by the union of several OpenAPI specifications:
rpc-openapi(-rc).json, containing the protocol-independent (or “shell”) RPCs
For each protocol in use:
$PROTOCOL-openapi.json(served under the prefix:
$PROTOCOL-mempool-openapi.json(served under the prefix:
For instance, for an RPC listed as
GET /filter in
$PROTOCOL-mempool-openapi.json, its real endpoint is
These OpenAPI specifications, detailed below, can be generated by running the Octez node as shown in section How to Generate. For convenience, the files generated from the most recent release(s) are provided in this page, annotated each time with the corresponding release (in parentheses).
There exists an alternative reference for the node RPCs, presented in more static pages (e.g. Oxford RPCs - Reference for the active protocol). However, the static referece omits some RPCs, such as the ones related to the mempool.
The links below to the different OpenAPI specifications are opened using the Swagger UI integrated in GitLab. This UI can be used for browsing the OpenAPIs (no need to install Swagger UI for that). However, the interactive use suggested in this UI does not currently work because:
the UI does not allow one to specify a server (which should correspond to a runnning Tezos node), and
browsers may block some of the generated requests or responses for security issues.
The node provides some RPCs which are independent of the protocol. Their OpenAPI specification can be found at:
The OpenAPI specifications for RPCs which are specific to the Oxford (
protocol can be found at:
The OpenAPI specifications for RPCs which are related to the mempool and specific to the Oxford protocol can be found at:
Smart Rollup Node¶
The smart rollup node exposes different RPCs depending on the underlying L1
protocol in use. Their specification is given in the sections below.
(The exact versions of the rollup node for which these files are produced can be
seen in the field
.info.version within each file.)
The OpenAPI specifications for the RPCs of the smart rollup node for the Oxford
Proxford) protocol can be found at:
How to Generate¶
To generate the above files, run the
from the root of the Octez repository.
It will start a sandbox node, activate the protocol,
get the RPC specifications from this node and convert them to OpenAPI specifications.
To generate the OpenAPI specification for the RPCs provided by a specific protocol, update the following variables in src/bin_openapi/generate.sh:
protocol_hash, use the value defined in
How to Test¶
You can test OpenAPI specifications using Swagger Editor
to check for syntax issues (just copy-paste
rpc-openapi.json into it or open
it from menu
File > Import file).
You can run Swagger UI to get an interface
to browse the API (replace
xxxxxx with the directory where
rpc-openapi.json by the file you want to browse):
docker pull swaggerapi/swagger-ui
docker run -p 8080:8080 -e SWAGGER_JSON=/mnt/rpc-openapi.json -v xxxxxx:/mnt swaggerapi/swagger-ui
Then open it in your browser.
