n8n Workflow Generator — turn plain English into a ready-to-import n8n workflow

Describe your automation in one sentence. Get back a validated n8n workflow JSON you can import in one click. No subscription — pay only per generated workflow. Built for humans and AI agents (x402-ready).

Stop hand-wiring nodes or debugging broken JSON from ChatGPT. This Actor generates the workflow and validates it against the real n8n node registry before you're charged. If it doesn't pass validation, you don't pay.

What you get

• generate mode — $2.99: a plain-English task → a complete n8n workflow (trigger, nodes, connections, layout) as import-ready JSON. Checked against 560+ real n8n node types and auto-repaired before delivery. Invalid result = no charge.
• validate mode — $0.10: paste an existing workflow JSON → an import-readiness report (missing fields, broken connections, unknown/hallucinated node types, missing trigger, orphan nodes).

Why not just ask ChatGPT (or a free generator)?

Raw LLM output for n8n routinely hallucinates node types, breaks the connections wiring, or forgets the trigger — it looks right and fails on import. This Actor validates every result against the actual n8n node registry and runs up to two automatic repair rounds. You get JSON that imports cleanly, not a plausible-looking dead end. And when you don't (rare), you're not billed.

Compared to free "bring-your-own-key" generators, there's nothing to set up: no OpenAI/Gemini API key, no webhook, no self-hosted instance. You call it, you get a validated workflow, you pay only for what passes — and an AI agent can call it the same way over x402.

Real examples (actually generated by this Actor)

Input: "When a new row appears in my Google Sheet, send its contents to a Slack channel #leads" Output: Google Sheets Trigger → Slack — 2 nodes, valid, first try.

Input: "Every Monday at 9am fetch an RSS feed, summarize new items with AI, and email me the digest" Output: Schedule Trigger → RSS Read → IF (new items) → Set → OpenAI → Format → Email — 8 nodes, branching, valid.

Input: "When my webhook receives a JSON order, if total > 100 send it to Slack #vip, otherwise append to Google Sheets" Output: Webhook → IF → Slack (true branch) / Google Sheets (false branch) — correct two-way branching, valid.

How to use

1. Set mode = generate.
2. Type your automation in task (plain English — mention the apps and the trigger).
3. (optional) Add notes for constraints (which services, error handling, naming).
4. Run. Grab the workflow from the dataset (workflow field) or key-value store (workflow.json).
5. In n8n: Workflows → Import from File / Paste JSON → connect your credentials → done.

Output

A dataset record with:

• workflow — import-ready n8n JSON
• valid — passed structural validation
• warnings — non-blocking notes (e.g. a node type outside the known registry)

Call it from an AI agent (x402 / MCP)

No account or API key needed — an agent pays per call in USDC on Base via x402:

• Direct (x402): POST https://api.apify.com/v2/acts/primeflowio~n8n-workflow-generator/run-sync-get-dataset-items with body {"mode":"generate","task":"<plain English>"}. The endpoint returns HTTP 402 with payment requirements; settle it (e.g. via Coinbase's awal client) and the run streams back the validated workflow.
• Via Apify MCP server: connect to https://mcp.apify.com and the actor is discoverable/callable as a tool (search-actors → call-actor).

Perfect for

• AI agents (callable as a tool via x402 and the Apify MCP server — pay per call, no account or API key needed): give your agent the ability to build automations, not just describe them.
• n8n users on self-hosted / community who don't have the Cloud AI builder.
• Anyone who wants a working workflow in seconds instead of 30 minutes of node-wiring.

FAQ

Do I need my own AI API key? No. It's fully hosted — no OpenAI/Gemini key, no setup. You pay per validated workflow, nothing else. Does it need my n8n instance? No. It returns JSON — you import it into any n8n (cloud or self-hosted). Will it invent credentials? No. It sets parameters normally; n8n prompts you for credentials on import. What if the result is broken? You're only charged for workflows that pass validation. Which nodes does it know? The full current n8n registry (n8n-nodes-base + langchain nodes) — 560+ types, regenerated from the official repo.
