HTTP & Rest

The HTTP endpoints enable simple selection and modifications of all records or a single record in a table, in addition to support for custom SurrealQL queries with multiple statements, using traditional RESTful HTTP url endpoints.

Accessing Endpoints via Postman

The most convenient way to access these endpoints is via SurrealDB’s Postman Collection. To do so, follow these steps:

1. Open Postman
2. Clone the SurrealDB Postman Collection
3. Select the appropriate HTTP method (GET /health, DEL /key/:table, etc.).
4. Enter the endpoint URL.
5. If the endpoint requires any parameters or a body, make sure to include those in your request.

Important

Ensure that your URL is set correctly, if running locally, the URL should be http://localhost:8000.By default, the URL is set to local. Start your server using the surreal start command in the CLI or through Surrealist’s local database serving functionality, before querying the endpoints.

You can use the HTTP endpoints to perform the following actions:

GET /status

This HTTP RESTful endpoint checks whether the database web server is running, returning a 200 status code.

Example usage

Request
curl -I http://localhost:8000/status

Sample output
HTTP/1.1 200 OK
content-length: 0
vary: origin, access-control-request-method, access-control-request-headers
access-control-allow-origin: *
surreal-version: surrealdb-2.0.0+20240910.8f30ee08
server: SurrealDB

date: Wed, 11 Sep 2024 00:52:49 GMT

GET /health

This HTTP RESTful endpoint checks whether the database server and storage engine are running.

The endpoint returns a 200 status code on success and a 500 status code on failure.

Request
curl -I http://localhost:8000/health

Sample output
HTTP/1.1 200 OK
content-length: 0
vary: origin, access-control-request-method, access-control-request-headers
access-control-allow-origin: *

Headers

Example usage

Note

The -u in the example below is a shorthand used by curl to send an Authorization header.

Request
curl -X POST -u "root:root" -H "ns: mynamespace" -H "db: mydatabase" -H "Accept: application/json" -d path/to/file.surql http://localhost:8000/import

Request

POST /signin

Method and URL
POST /signin

This HTTP RESTful endpoint is used to access an existing account inside the SurrealDB database server.

Headers

Data

Important

The ac parameter is only required if you are signing in using an access method as a record user. For system users on the database, namespace, and root level, this parameter can be omitted.

Example with a Record user

Request

Example usage via Postman

After you have defined the users permissions for the record user, you can use the POST /signin endpoint to sign in as a user.

Using the user credentials created add the following to the request body:

    "db": "test",
    "ac": "account",
    "email": "",
    "pass": "123456"
}

}

Example usage via Postman

Before you sign up a new record user, you must first define a record access method for the user. To do so, follow these steps:

Note

You can also define system users and user credentials using the POST /sql endpoint.

1. Navigate to the POST /sql endpoint in Postman.
2. Enter the following query in the body of the request:

-- Enable authentication directly against a SurrealDB record
DEFINE ACCESS account ON DATABASE TYPE RECORD
    SIGNUP ( CREATE user SET email = $email, pass = crypto::argon2::generate($pass) )
    SIGNIN ( SELECT * FROM user WHERE email = $email AND crypto::argon2::compare(pass, $pass) )
    DURATION FOR SESSION 24h
;

The above query defines a record access method called account that allows users to sign up and sign in. The access method also defines the session duration to be 24 hours.

3. Click Send to send the request to the SurrealDB database server.
4. Navigate to the POST /signup endpoint in Postman.
5. Enter the following query in the body of the request:

{
    "ns": "test",
    "db": "test",
    "ac": "account",
    "email": "",
    "pass": "123456"
}

6. In the header of the request, set the following key-value pairs:
   • Accept: application/json
   • namespace: test
   • database: test
   • access: account
7. Click Send to send the request to the SurrealDB database server. You will get back a

POST /ml/import

This HTTP RESTful endpoint imports a SurrealML machine learning model into a specific Namespace and Database. It expects the file to be a SurrealML file packaged in the .surml file format. As machine learning files can be large, the endpoint expects a chunked HTTP request.

Headers

Example usage

When using Python, the surreaml package can be used to upload the model with the following code:

from surrealml import SurMlFile

url = "http://0.0.0.0:8000/ml/import"
SurMlFile.upload("./linear_test.surml", url, 5)

GET /ml/export/:name/:version

This HTTP RESTful endpoint exports a SurrealML machine learning model from a specific Namespace and Database. The output file with be a SurrealML file packaged in the .surml file format. As machine learning files can be large, the endpoint outputs a chunked HTTP response.
