Nodle APIs

Introduction to Nodle APIs

Nodle has several APIs you can use to connect with the Nodle Network or the services built on it.

  • The SDK API and IoT API may be used by enterprise customers to manage their SDK instances and interact with the Asset Tracking service.
  • The Treasury Allocations API, Token Issuance API and SubQL indexer API may be used to query various states and statistics about the Nodle Chain.

IoT API

💡
The IoT dashboard is currently in private beta. Contact the team (partners@nodle.com) to get Beta access.

Getting started

We consider that at this point, you are already onboarded on the IoT dashboard and that you have organizations created.

APIs

Please note that there are two different APIs :

  • SDK API: manage your account, your organizations, your API keys,...
    • Base URL : https://api.sdk.nodle.io/api/v1/
  • IoT API: retrieve data from your fleets and devices.
    • Base URL : https://iot.nodle.com/api/v1/

In order to use the IoT API, you will have to create an API key directly from SDK API. Everything is described in the following steps.

SDK API authentication

Go to IoT dashboard or SDK dashboard and sign in using your email. Right after, you should receive an email containing a magic link that should looks like https://iot.nodle.com/?token={token}. Please copy this token, we will need it to authenticate requests later.

Note: Please note that the magic link's URL will always look like https://iot.nodle.com/?token=****** or https://sdk.nodle.com/?token=******, every other link format should be considered as phishing.

Create your API key

Once you have your token, you will be able to create your API key with /api/v1/currentuser/apikeys SDK API endpoint:

curl -X 'POST' \
'https://api.sdk.nodle.io/api/v1/currentuser/apikeys' \
-H 'accept: application/json' \
-H 'Authorization: Bearer {YOUR_TOKEN}' \
-H 'Content-Type: application/json' \
-d '{
"displayName": "My First API Key!"
}'

If your request is valid, you will receive your newly created API key:

{
"id": 1234567,
"display_name": "My First API Key!",
"apikey": "{YOUR_API_KEY}",
"created_on": "2022-12-20T07:58:26.198146239Z",
"updated_on": "2022-12-20T07:58:26.198146239Z"
}

Note: API key are very sensitive information and let anybody access your data if leaked, please take great care of it.

Find you organization ID

For most IoT API calls, you will need to know what's your organization ID. To find it out, please use api/v1/currentuser/organizations SDK API endpoint :

curl -X 'GET' \
'https://api.sdk.nodle.io/api/v1/currentuser/organizations' \
-H 'accept: application/json' \
-H 'Authorization: Bearer {YOUR_TOKEN}'
[
{
"id": 123456,
"display_name": "Umbrella Corp.",
"data_addendum": true,
"verification_status": true,
"roles": [
"admin"
],
"created_on": "1968-07-22T09:57:17.497291Z",
"updated_on": "2022-08-15T14:58:51.627868Z"
}
]

Start using IoT API

With API key and organization ID in our hands, we are now able to use the IoT API :

curl -X 'GET' \
'https://iot.nodle.com/api/v1/organizations/{YOUR_ORGANIZATION_ID}' \
-H 'accept: application/json' \
-H 'x-api-key: {YOUR_API_KEY}'
{
"data": [
{
"bearer": null,
"enabled": false,
"id": "1e5677de-002e-4278-9b1c-909881b33962",
"identifier": "ibeacon:ace34cb9-d541-473e-8d77-a8e07a1df7dc",
"inserted_at": "2021-09-21T16:40:03",
"name": "Umbrella Corp. Fleet #1",
"organization_id": 123456,
"routing_target": null,
"routing_type": null,
"updated_at": "2022-11-21T18:41:17"
}
]
}

Token Issuance API

GET /v1/total-issuance

This API endpoint retrieves the total number of NODL tokens minted up until the time the API is called.

URL: api.nodle.com/v1/total-issuance

Method: GET

Auth required: No

Data Params: None

Success Response:

Code: 200 OK

Content: <number>

Sample Call:

curl -X GET <https://api.nodle.com/v1/total-issuance>

Notes:

The total issuance number is dynamic and changes as new Nodle tokens are minted. The returned number is of type float with 1 NODL as its unit. Here is an example of the returned value: 8555296342.716467.

This design for this API is solely for the convenience of third party coin market reporters such as coinmarketcap.

SubQL indexer API

The purpose of this documentation is to illustrate how to debug a GraphQL playground.

At present, we utilize services to index data from the chain. This helps to reduce load on the RPC nodes, resulting in a healthier network. It's important to note that this approach is only intended to support reads to the chain state. Starting from listing the projects we had you can go to:

https://managedservice.subquery.network/orgs/NodleCode/projects

Each project has its own playground, which provides an easy way to interact with the indexed data.

For more information, refer to this documentation: https://academy.subquery.network/run_publish/query.html

As stated in the document, we can use clients to send fast and reliable requests to the GraphQL service. Each client has its own documentation.

How to query the GraphQL without presets clients?

We need to start recognizing the entities created on the service. Here you will find the schema we have created for our main node:

https://github.com/NodleCode/subquery/blob/dddfb30a7772f895282ab19086bb2187b3679f76/schema.graphql

Based on the available information, we can construct our own queries and send them using curl.

Here, we use the entities generated based on the schema we shared earlier.

query {
accountPotBalances (first: 5) {
nodes {
id
potId
accountId
feeQuotaBalance
}
}
pots (first: 5) {
nodes {
id
potId
owner
feeQuotaBalance
}
}
}

Having the query already built, we can send it with curl like this way, where YOUR_GRAPHQL_ENDPOINT_URL is the service url

curl -X POST -H "Content-Type: application/json" --data '{ "query": "{ accountPotBalances (first: 5) { nodes { id potId accountId feeQuotaBalance } } pots (first: 5) { nodes { id potId owner feeQuotaBalance } } }" }' YOUR_GRAPHQL_ENDPOINT_URL

Treasury Allocations API

GET /v1/treasury-allocations/[date]

This API endpoint retrieves the total balance transferred to the Treasury account from allocations by a given day

URL: api.nodle.com/v1/treasury-allocations/[date]

Method: GET

Auth required: No

Data Params: This endpoint require a route param

[date]: The target date should be formatted as YYYY-MM-DD, for example, if the target date is 2022-09-20, the final URL should be api.nodle.com/v1/treasury-allocations/2022-09-20.

Success Response:

Code: 200 OK

Content: <object>

Sample Call:

curl -X GET <api.nodle.com/v1/treasury-allocations/2022-09-20>

Notes:

This endpoint is intended to help in accountant process.
