A live data node for your n8n workflows.
Drop an HTTP Request node into any n8n workflow, POST to one keyless URL, and your automation gets 87 tools of fresh data the workflow otherwise lacks - weather, CVEs, service status, macro rates, hazards.
The call
Use n8n's built-in HTTP Request node (method POST, no credentials) pointed at /v1/batch, or run this curl to see the exact JSON shape your node receives. Batch several tools in one call so one node fans out to many data sources:
curl -s -X POST https://dynamicfeed.ai/v1/batch \
-H "Content-Type: application/json" \
-d '{"calls":[
{"tool":"current_weather","args":{"city":"London"}},
{"tool":"service_status","args":{"service":"openai"}},
{"tool":"exploited_vulnerabilities","args":{}}
]}'Sample response
// n8n HTTP Request node
// Method: POST
// URL: https://dynamicfeed.ai/v1/batch
// Authentication: None
// Body (JSON):
{
"calls": [
{ "tool": "weather_forecast", "args": { "city": "Sydney" } },
{ "tool": "interest_rates", "args": {} }
]
}Why live data
n8n is built on HTTP nodes, so the cleanest "live data node" is just a POST to one keyless endpoint - no custom node to install, no credential to manage, no key to rotate. Every datapoint comes back with provenance (source, observed-at, freshness state) and an Ed25519 signature, so a downstream node or an audit log can confirm the payload was not altered after we returned it. Be precise about what that signature means: it is proof-of-existence and tamper-evidence - it proves Dynamic Feed reported value X at time T and that the bytes were not modified in transit. It is not a claim that X is true, accurate, or safe to act on; that judgement stays in your workflow. The 87 tools cover live operational and macro data (weather, CVEs, service status, interest_rates, treasury_yields, hazards) - there is no live crypto, metal, or stock price conversion here; the finance tools are macroeconomic and rates data, not market prices.
Use it for
- Branch an n8n workflow on a city's weather_forecast or weather_alerts before sending a notification
- Gate a deploy or alert flow on service_status (is OpenAI/GitHub up?) and exploited_vulnerabilities
- Enrich incoming records with interest_rates or treasury_yields without managing an API key
- Fan out one HTTP node to many live sources via a single /v1/batch call, then split the results
FAQ
Do I need an API key or n8n credential?
No. Set the HTTP Request node's Authentication to None and POST to https://dynamicfeed.ai/v1/batch. The endpoint is keyless and free for fair use.
Do I have to install a custom n8n community node?
No. Use the built-in HTTP Request node with method POST and a JSON body of calls. That is the whole integration - nothing to install or maintain.
Can one node fetch from several sources at once?
Yes. Put multiple tools in the calls array of a single /v1/batch POST and the node returns one results array, which you can split in a downstream node. There are 87 tools across 19 verticals and 70 sources.
