Made something good? Sell it to AI agents.
Turn a dataset, a paper, or any file into something AI agents can buy — with built-in proof it came from you and hasn't been changed. A no-code way in: no servers, no code, and no one holding your money — you're paid directly in USDC to your own wallet. You keep everything; Lemma is just the tool.
Only the real earns a price.
Scraped versions and AI-made imitations sit right next to your original — without proof, an agent can't tell which one is really yours. Real, verifiable, original: exactly what agents will pay a premium for.
Being real gets it chosen
It carries who, when, and unaltered — and AI prefers sources it can verify.
Direct means you keep more
You license the original yourself — no middleman skimming your cut.
The real gets scarce
As generated content floods the web, verified human originals only grow more valuable.
Three steps. You only do the first one.
The rest is automatic. You don't write code, run a server, or manage payments.
Point to your file
Upload a dataset, a paper, or an export. That's your whole job.
We stamp it and set your price
We attach a proof that it's yours and unchanged, add the price you chose, and turn it into something payable. Zero setup.
It gets found, checked, and bought
An AI agent discovers your listing, checks the proof for free, and pays you automatically. You get paid; it gets a source it can cite.
Checking your proof is always free. You get paid for the data — not for being trusted.
If you made it, an agent can cite it.
Research work is exactly what AI agents are hungry for — real, structured, and verifiable. A few things people put up:
The training data you built and annotated by hand.
Messy sources you turned into something usable.
Experiment numbers others want to build on.
The how — pipelines, prompts, reproducible steps.
Whatever you put up becomes a resource an agent can trust, pay for, and cite back to you.
What you actually do: pick a file, set a price — in the Dashboard.
Nothing to wire up, no code — and you can rehearse the whole thing for free before anything goes live.
In the Dashboard, point to a file and set a test price. It runs on a test network, so no real money moves. Break things, retry, get comfortable. Students start here.

If your lab registers, everyone in it publishes free.
Registered institutions are just coming online.
Your lab registers once
A lab or university signs up as the institution. After that, every member can publish under its name.
You publish under the umbrella
No separate plan or cost for you — just point to your file and set a price.
Credit follows you
Everything is attributed to you by name. Move on, and your proofs still check out.
It starts with getting this page in front of your lab.
Pay only when you really sell.
Checking proofs is always free — you're billed only for issuing them, and sales carry no commission.
- Practice proof issuance & listing on testnet
- By form or by API — both
- No production proof issuance (zero cost)
- Ready for real, production listings (testnet practice is Explorer)
- Each listing issues its provenance proof, settled via x402 — no listing, no cost
- Publish freely, within fair use
- Provenance with proof of authenticity, persisted on-chain
- Reliable operation & priority support (SLA)
- Institution verification (registry + domain) + attribute attestation
- Members publish free — vouched by the institution's roster
- Bulk enrollment (CSV / API) & revocation management
- Affiliation-lookup service (planned)
Your monthly plan pays for your storefront. Proof of authenticity comes standard on every listing.
0% commission on sales — you keep 100% of every sale, paid directly in USDC to your own wallet (self-custody; we never hold your funds).
Agents verify proofs for free — always.
Normal publishing stays within fair use at no extra cost. Only high-volume automated issuance (e.g. via API) is metered — 0.005 USDC per proof, settled per issuance via x402. Set a spend cap and it stops automatically at your ceiling. Prices exclude tax.
Good things to check.
What stays yours
- ✓Full ownership of your work — always.
- ✓The right to sell or share it anywhere else, too.
- ✓Your name on it, as the recognized source.
- ✓You set the price, and you can change it.
What you don't need
- ✕A server, or any code to write.
- ✕A storefront or marketplace account to set up.
- ✕To hand over your raw data just to prove it's real.
- ✕A custodian — you're paid directly in USDC; we never hold your funds.
I've never done this — where do I start?
In the free sandbox. In the Dashboard, point to a file and set a test price, watch the whole flow, and pay nothing. When it clicks, going live takes the same steps.
How do I get paid? Do I need to know crypto?
In USDC, a digital dollar, straight to your own wallet — self-custody, we never hold your funds. When an agent buys your work, payment settles automatically, no invoicing. If you don't have a wallet, setting one up is a one-time ~2-minute step; we handle all the proof and payment plumbing behind the scenes.
Do I have to hand over my data to prove it's mine?
No. Agents check a proof, not the raw file. Your file is stored encrypted and released only to buyers who have completed payment.
I'm a student — where do I start, and is there a cost?
Two steps. First, try everything free in the sandbox — no affiliation, no real money. When you're ready to go live, publish free under your university's or lab's Institutional plan, still credited to you by name. If your institution isn't registered yet, start by sharing this page with your lab.
→ Share this with your labWhat happens if I sell without proof?
Selling itself you can do anywhere. But without proof, agents can't tell your original from a scraped copy or an AI imitation. Verifiable primary sources get chosen first — and if a payment or citation goes to someone else, you have no way left to show the work was yours. Your sales don't accumulate into a track record, either.
Is this a marketplace? Does Lemma resell my data?
No. You sell; Lemma is just the tool that makes it possible. Discovery happens in the open x402 Bazaar.
