“Signatures can’t prove non-reuse.”
The limit lives in a mutable counter. Two replicas that don’t share state hand the agent 2N actions, and neither notices.
Before the pitch. Before the attorney.

Marklode drills through your idea the way a VC associate would: the competitors, the patents, the attacks, the verdict. The check before a five-figure patent search, in 24 to 72 hours.

A founder sent two paragraphs and a plan to file a patent.
This is what came back, published with their permission. Scroll through the same four layers every report goes through.

A credential for AI agents that is consumed by use. The agent gets a fixed number of one-time keys — say 200 — and each API request burns one. The number of keys remaining is the agent's authority; when it hits zero, the agent stops. If a key is ever used twice, that proves the credential was cloned.
01 · Landscape
Who is already here.
Before anything else, we map the room: identity platforms, payment protocols, standards drafts, and who just bought whom.

03 · Hostile review
Three attacks, written to kill it.
The arguments an investor or competitor would make. If you can’t answer these in the room, you don’t walk in.
“Just use short-lived tokens.”
The industry’s answer to blast radius is a 60-second token. The rebuttal is real, but it argues for counting, which AP2 already does.
“One Postgres row handles it.”
A single hot row sustains about 14,500 updates a second. A 1,000-action budget uses 7% of one second of it, total.

04 · Verdict
Four conditions. Then the stamp.
A business survives when a buyer can’t exit, the free fix is worse, no incumbent holds the segment, and harm converts to money.

The core mechanism was patented by Amazon in 2016. An examiner would reject the claim at first action.

What survives
The observation, not the mechanism. Two flagship commerce protocols mandate cumulative action limits and specify enforcement nowhere, and nobody ships action budgets for agents as a product. That is a business thesis worth building.

How it’s done
Every finding is checked by a person and linked to its source before it reaches you. AI tools do the breadth, hundreds of sources per report, so the person can spend their time on judgement: which patents actually read on your mechanism, and which attack would sink you. You can check every line of the work.
What it isn’t
Legal advice or a freedom-to-operate opinion. If the report finds a patent that reads on your idea, it says so and tells you to call an attorney, and you walk in knowing exactly which patent to ask about. NDA on request.
Confidentiality
How we handle your idea.
You are sending something you may not have told investors yet. This is exactly what happens to it.
01 · NDA
NDA first, if you want one.
Ask before you share any detail. Send your NDA and we sign it before you send the brief. We don’t negotiate terms. No NDA of your own? Use our mutual NDA.
02 · WHO SEES IT
One person, plus the research tools.
One person at Marklode reads your brief and reviews the report. The research runs on AI tools, currently Anthropic’s Claude, and every finding is checked by hand.
03 · PUBLIC SOURCES
We don’t tell anyone.
We search patents, papers, standards and funding news. We don’t contact your competitors, investors or anyone else about your idea.
04 · ONE USE
Used for your report, nothing else.
Your brief isn’t reused, resold or pitched to anyone. A report is published as a sample only with your written permission, as Stress Test No. 0001 was.
05 · AFTER DELIVERY
Yours to keep, or to have deleted.
The report is delivered through Fiverr or Upwork, and those platforms keep order messages under their own terms. Ask after delivery and we delete the brief, notes and report files we hold.
FAQ
Before you order.
The questions founders ask most, answered straight.
What do I need to send?
Two to five sentences about the idea, who the customer is and what they do today instead, any competitors you already know of (or “none known”), and whether you’re preparing to raise, file a patent or build. That last answer changes where the report puts its emphasis. No deck required.
How is this different from asking an AI to research it?
A model gives you a list; this gives you a verdict. Every claim is checked by a person and linked, the prior-art pass reads what the closest patents actually claim, and the hostile review is written to kill the idea, not to reassure you.
Will you tell me my idea is bad?
If the evidence says so, yes. That’s what you’re paying for. Most reports find the idea is partly taken and identify the part that isn’t, and that narrower claim is usually the one worth building.
Is this a patent search or legal advice?
It’s a prior-art landscape, not a legal opinion or a freedom-to-operate search. It finds the patents that matter and tells you what they claim, so your conversation with an attorney is short and specific.
What if you find nothing?
Then you get a report that says so, with the search recorded, so an investor can see the diligence was done. And if the report doesn’t surface at least three competitors, patents or papers you didn’t already list, the three-findings guarantee gives you a full refund.
Do you sign an NDA?
Yes. Send yours and we sign it before you share the brief, or use our mutual NDA. Nothing you share is used for any other purpose.
How fast is it?
24, 48 or 72 hours depending on the package. Rush delivery is available on Full Teardown and Investor-Ready.
How do payment, revisions and refunds work?
Orders run through Fiverr or Upwork, which handle payment, cancellations and refunds under their own terms. Landscape includes one revision, Full Teardown two and Investor-Ready three.
