The usual rough start

So, you're building an AI agent...

You will have to wire up complex workflows to deal with:

  • Unification

    Stitch bursts of messages back into one clean prompt before your agent sees them.

  • Rate limiting

    Throttle floods of requests before they ever reach — and overwhelm — your agent.

  • Token bombs

    Detect and block oversized payloads that quietly burn through your LLM budget.

  • Deduplication

    Catch the same webhook fired twice so your agent never acts on it more than once.

  • Routing

    Send each message to the right workflow instead of one bloated catch-all.

  • User's blacklist

    Keep banned or abusive users out before they cost you a single token.

  • and more...
Overlapping complex n8n workflows for deduplication, rate limiting, unification, validation
The result:
You will lose time on setup
Workflows get more and more complex
Maintenance becomes a nightmare

Take a breath — none of that is yours to build.

Portarus already took care of it.

What you get

You build the agent. Everything underneath is already handled.

One quiet layer in front of your webhook does the work you'd otherwise wire by hand — so you stay focused on what your agent actually says.

01 Unification

Your users don't send one clean message. They send four.

  • Every burst stitched into one complete prompt.
  • 4 webhook triggers → 1 execution.
  • Your LLM reads the whole intent, not fragments.
  • You wire nothing.
Fewer executionsOne execution instead of four per burst.Lower billStay on a cheaper n8n / Make / Zapier tier for longer.Better contextYour agent reads the whole message, not pieces.
Unification — Your users don't send one clean message. They send four.
02 Protection

Everything hostile stops at the gate — not inside your agent.

Only clean, valid traffic ever reaches you. Three guards, always on:

Rate limiting

Floods throttled per user before they overwhelm your agent.

Token bombs

Oversized payloads rejected before they burn your LLM budget.

Deduplication

The same webhook fired twice never gets acted on twice.

No spam, no duplicate charges, no attacks slipping through. Sleep tight.

No wasted tokensJunk never touches your LLM budget.No double chargesDuplicates dropped before they bill you.Fewer attacksHostile traffic stopped before it reaches your agent.
Protection — Everything hostile stops at the gate — not inside your agent.
03 Routing

One endpoint. The right workflow, every time.

  • Each message sent to the workflow built for it.
  • Support here, sales there, billing elsewhere.
  • No bloated catch-all that breaks on everything.
  • Add a flow without touching the ones that work.

Routing — One endpoint. The right workflow, every time.
04 User blacklist

Banned once, gone for good.

  • Abusive or banned users stopped at the door.
  • Blocked before they cost a token or an execution.
  • Set the rule once; enforced on every request.
  • A spammer can't drain your budget overnight.
Budget protectedA blocked user can't burn tokens or executions.Set and forgetDefine the rule once; Portarus enforces it.
User blacklist — Banned once, gone for good.

And a few more things it checks, quietly -- you won't have to handle:

malformed payloads · JSON nesting / depth · required fields · oversized bodies · per-message token limits · SSRF-safe routing

Your questions, answered.

Do I need to code?

No. One link, pasted where your webhook already goes.

Will it break my AI agent?

No. If Portarus ever fails, your messages pass through untouched.

Can I remove it?

Yes. Switch the link back anytime. Nothing to undo.

Does it work with my tool?

Yes — n8n, Make, Zapier, LangChain, any webhook.

Is it really free?

Yes. 3,000 runs a month, no card.

Is {BRAND} the agent?

No — it sits in front of your agent and cleans what reaches it.
