Query

To query the nodegoat API you need a valid domain, a valid path, and a valid query component. The following example URLs contain some of the possible basic domain, path, and query parameters:

Unauthenticated domain 'demo', access default Project, get the OpenAPI description:

GET 'https://demo.nodegoat.io/.openapi'

Unauthenticated domain 'demo', access default Project, inspect the Project as an MCP server:

GET 'https://demo.nodegoat.io/.mcp'

Authenticated, access Project 1, access Project’s data, Type 2, apply Scope 3, apply Filter 4, request Object 5 & 6 & 7, request Object 8, quick search for 'A', apply a JSON-formatted filter form:

GET 'https://nodegoat.io/project/1/data/type/2/scope/3/filter/4/object/5,6,7?object_id=8&search=A&filter={}' -H 'Authorization: Bearer TOKEN'

Authenticated, access Project 1, access Project’s data Model, request Types 2 & 3 & 4

GET 'https://nodegoat.io/project/1/model/type/2,3,4' -H 'Authorization: Bearer TOKEN'

Authenticated, access Project 1, access Project’s Filters, request Filter 2 & 3:

GET 'https://nodegoat.io/project/1/feature/filter/2,3' -H 'Authorization: Bearer TOKEN'

Domain  

The domain indicates whether you are creating an authenticated or unauthenticated/open request.

Authenticated

When making an authenticated request, HTTPS is required and should query nodegoat’s main API domain at nodegoat.io or api.nodegoat.net.

Unauthenticated

To make an unauthenticated request, you use the subdomain of your nodegoat Domain’s to query the nodegoat API over unencrypted HTTP at DOMAIN.nodegoat.io or api.DOMAIN.nodegoat.net. When you have an institutional installation of nodegoat you use the main API domain, you also have the option to use HTTPS.

Path  

The path tells the API what Project and what data you want to access.

//nodegoat/A  

Specify which nodegoat Project to access. Optional.

ADescription
/ project / IDAccess a specific nodegoat Project. If this is left out, the default configured Project is assumed.

//nodegoat/A.openapi  

Append .openapi to access the OpenAPI description for using the nodegoat API with the selected Project. The .openapi is set-up to provide a full machine-readable and promptable description for the Project. Optional.

//nodegoat/A.mcp  

Append .mcp to access the selected Project as an MCP server. The .mcp is generated from the Project’s .openapi description and presents every operation as a tool an AI client can call. Optional.

//nodegoat/A/B  

Specify the mode. One of the following parameters has to be provided.

BDescription
/ ID or ?id = IDDirectly access Objects with their corresponding nodegoat IDs or other identifiers (see data Model on how to indicate what Object Descriptions can be used for identification). The ID can also be provided using the query component id (both GET and POST). The query component has to be used when identifiers contain characters reserved for URLs.
/ dataAccess the Project’s data.
/ modelAccess the Project's data Model.
/ featureAccess the Project's Filters, Scopes, and Conditions. These use the data Model, but are not part of it.

Specify for which Type you want to access the data.

CDescription
/ type / IDAccess data for the specified Type.

//nodegoat/A/B:data/C/D  

Apply Project- and Type-specific operations to the request. More than one of the following parameters can be provided. Optional.

DDescription
/ scope / IDApply the specified Scope to the request. This allows you to generate highly-relational and ready-to-use data structures using nodegoat Scope functionality.
/ filter / IDApply the specified Filter to the request. Additionally, the Filter can be manipulated in the query component of the request.
/ condition / IDApply the specified Condition to the request to format the output.

//nodegoat/A/B:graph/C/D/E  

Get the graph from Analysis.

EDescription
/ analysis / IDApply the specified Analysis settings and output the graph / edge list.

Component  

The query component allows you to further specify your request by means of search parameters. It is also possible to POST the query component instead of using GET (e.g. when using JSON in the request).

//nodegoat/A/B:data/C/D/E?Q  

All parameters in the query component are optional. When combined, each additional parameter will filter the result (AND).

Query the API for a Type's data Model to get an overview of the possible IDs for Object Descriptions, Sub-Object Details, and Sub-Object Descriptions.

QDescription
object_id = ID(,ID)Select the specified Object(s).
search = valueQuick search Objects for value.
filter = ID or
filter = JSON or
filter = Endpoint Dictionary
Apply a JSON-formatted Filter. The filter parameter allows you to customise and apply full-featured nodegoat Filters to your query. Access / feature / filter for the Project's stored Filters and how the form is composed.

A Filter form has to filter: one that parses but narrows nothing is answered with an error, not with every Object of the Type.

scope = ID or
scope = JSON
Apply a JSON-formatted Scope. The scope parameter allows you to customise and apply full-featured nodegoat Scopes to your query. Access / feature / scope for the Project's stored Scopes and how the form is composed.
condition = ID or
condition = JSON
Apply a JSON-formatted Condition to format the output. The condition parameter allows you to customise and apply full-featured nodegoat Conditions to your query. Access / feature / condition for the Project's stored Conditions, what each one changes, and how the form is composed. A Condition is applied on top of the Conditions the data Model and the Project already apply.
output = outputSpecifiy the output format raw for native and fast output of the data without additional processing such as parsing Object names, or default.
order = element:ASC or
order = element:DESC or
order = JSON
Specify the Object's element used for ordering the output. An element could be one of the following: object_name, object_analysis, object_description_ID, date (Object version date).

Or, apply a JSON-formatted ordering form. The form can contain any of the following ranked properties and direction value specifying ASC or DESC:

{
"object": {
"object_name": "direction",
"object_analysis": "direction",
"object_description_ID": "direction",
"date": "direction"
},
"object_subs": {
Sub-Object Details ID: {
"object_sub_details_name": "direction",
"object_sub_details_date_start": "direction",
"object_sub_details_date_end": "direction",
"object_sub_description_ID": "direction"
}
}
}
limit = number or
limit = ∞
Limit the results to a maximum amount of Objects. Handy for pagination purposes. Defaults to 100, use for no limit. An unauthenticated request has a maximum of 10000, included. A request that specifies object_id has no default limit.
offset = numberOffset the results with a specific amount of Objects. Handy for pagination purposes. Needs a limit to offset from.
total = 1Include the amount of Objects the query selects (total_filtered) and the amount the Type holds (total) in the result. Counting needs a query of its own, so request it when pagination needs the number.

//nodegoat/A/B:model/C?Q  

All parameters in the query component are optional.

QDescription
output = outputSpecifiy the output format: template for relational name-based IDs instead of numeric IDs (easy for storage puposes, see store Model), or default.

//nodegoat/A/B:feature/C?Q  

All parameters in the query component are optional.

QDescription
type_id = IDLimit the results to the features that belong to the specified Type.

Response  

The result from your request to the nodegoat API can be found in the JSON response under the key data (if not specified differently in the next sections). The result is a JSON dictionary that promotes direct lookup and access to its structure.

The specific response depends on the mode (model, data, feature, or graph, see the Query path section above) of your request.

Response: Data  

In mode = data the result holds:

  • objects The requested or queried Objects with the Object's definition, keyed by Object ID.
  • count The amount of Objects returned.
  • offset The offset the query ran with.
  • limit The limit the query ran with, when unlimited. Not always the limit requested, a default applies when none is set and has a maximum without authentication.
  • total_filtered The amount of Objects the query selects, before limit and offset. Only on total = 1.
  • total The amount of Objects the Type holds. Only on total = 1.

Response: Model  

In mode = model the result holds:

  • types The requested Types with the Type's configuration, keyed by Type ID

Response: Feature  

In mode = feature the result holds:

  • filters, scopes, or conditions The requested Filters, Scopes, or Conditions.
  • instructions How to compose a Filter, a Scope, or a Condition form, and what a Condition changes in the output.

Each feature holds its own ID, the ID of the Type it belongs to, its name and description, and the form as it is stored, ready to be copied into the query component and adjusted, or into a request that stores a feature of your own. Two features hold one member more:

  • parameters The Endpoint Dictionary parameters of a Filter that takes them.
  • model_conditions The Conditions a stored Condition applies to the other Types.

Consult store feature to find more on the possible members.

Response: Graph  

The result from your request to the nodegoat API is a CSV file that includes the following columns:

  • key Identifier for the edge
  • from Start node
  • to End node
  • weight
  • time When applicable, this includes a sequence (white-space   separated) of start and end timestamps (comma , separated)
