Overview
This node fetches metadata related to sectors, industries, technologies, business models, states, and districts from the Kernal API. It is useful for workflows that require categorization or filtering of startup-related data based on these metadata types. For example, you can retrieve a list of all sectors or filter industries by a specific sector, or get districts filtered by state.
Common scenarios include:
- Enriching startup data with sector or industry classifications.
- Filtering datasets by geographic regions such as states or districts.
- Populating dropdowns or options dynamically in other nodes based on metadata fetched here.
Properties
| Name | Meaning |
|---|---|
| Metadata Type | Select the type of metadata to fetch. Options: Sector, Industry, Technology, Business Model, State, District |
| Filter Name or ID | (Shown only if Metadata Type is Industry or District) Filter industries by sector or districts by state. Choose from a list or specify an ID using an expression. |
Output
The node outputs an array of items where each item contains a JSON object with a single property:
name: The name of the metadata entry fetched from the API (e.g., a sector name, industry name, technology name, etc.).
Example output item:
{
"json": {
"name": "Agriculture"
}
}
No binary data is output by this node.
Dependencies
- Requires an API key credential for authenticating with the Kernal API. This credential must provide an authentication key and secret.
- Makes HTTP POST requests to the Kernal API endpoint at
https://startups.startupmission.in/api/v1/startup/meta/{metadataType}. - The node depends on n8n's HTTP request helper and credential management.
Troubleshooting
- Missing API credentials error: If the node throws an error about missing API credentials, ensure that the required API authentication token is configured correctly in n8n credentials.
- API request failures: Errors during the HTTP request to the Kernal API will be surfaced as node errors. Check network connectivity and validity of the API key/secret.
- Empty results: If no metadata is returned, verify that the selected metadata type exists and that any applied filters are valid.
- Filter option loading issues: The filter dropdown options depend on the selected metadata type and require successful API calls to populate. If these fail, the filter options may not load.
