BYOK (Bring Your Own Key) -- you provide your own API credentials.
Before You Start
This actor requires your own API credentials to fetch real data.
Where to get your key: JSON string of API keys for sources that require them
You can test with Demo Mode first (free, no key needed) to see the output format before committing.
Quick Start
Test with Demo Mode (free, no API key needed)
{"demoMode": true}
Run with real data
{"demoMode": false,"operation": "query","apiKeys": "YOUR_API_KEY_HERE","limit": 25}
Input Parameters
| Parameter | Type | Default | Required | Description |
|---|---|---|---|---|
operation | string | "query" | Yes* | The MCP operation to perform |
source | string | - | No | Specific data source to query |
sources | string | - | No | Comma-separated list of sources for multi_query |
task | string | - | No | Task to execute on the source |
query | string | - | No | Search query or natural language question |
params | string | - | No | JSON string of additional parameters for the query |
apiKeys | string | - | Yes* | JSON string of API keys for sources that require them |
limit | integer | 25 | No | Maximum results per source |
webhookUrl | string | - | No | URL to receive results via webhook |
demoMode | boolean | true | No | Run with sample data (no API calls) |

Pricing
This actor uses pay-per-event billing:
| Event | Description | Price |
|---|---|---|
| MCP Request | Each MCP tool request processed | $0.01 |
Demo mode is free -- no charges for sample data.
Troubleshooting
"API key is required"
You have Demo Mode turned off but didn't provide an API key. Either:
- Turn Demo Mode on to test with sample data
- Add your API key in the input
"API error 403" or "Unauthorized"
Your API key is invalid, expired, or doesn't have access to this specific API endpoint. Double-check your key and account permissions.
"API error 429" or "Rate limit"
Too many requests. Wait a minute and try again, or reduce the number of items per run.
No results or empty dataset
Check the run log for error messages. Common causes:
- Invalid input format (check the examples above)
- API key without proper permissions
- The target data doesn't exist or is too small to track
How do I test without an API key?
Enable Demo Mode in the input. This returns realistic sample data so you can verify the output format works for your workflow.
