objkt - Digital Art Marketplace on Tezos

objkt describes itself plainly: “We’re objkt, the largest digital art marketplace on the Tezos blockchain.”

The interesting thing about it is not the storefront. It is that you can query the whole marketplace without an account, and what that query reveals about who actually owns what.

We queried it, with no key

objkt publishes what its documentation calls “a free-to-use graphql API for developers” at https://data.objkt.com/v3/graphql. No sign-up, no token. One request, run while writing this:

curl -s -X POST https://data.objkt.com/v3/graphql \
  -H 'Content-Type: application/json' \
  -d '{"query":"{ fa(limit: 3, order_by: {volume_24h: desc_nulls_last})
       { contract name items } }"}'

It answered. The top three collections by recent volume came back with their Tezos contract addresses and item counts — and one of them is the point of this article:

contract	name	items
`KT1RtiwGrxXDDuxWBc5EkmFC9EM2BHsuqskT`	elementary animal collection for Morning and Night	39
`KT1RJ6PbjHpwc3M5rw5s2Nbmefwbuwbdxton`	hic et nunc	771,455
`KT1XaCf6gkjFnKg3QmPfn6gep53moMvjkj1E`	open objkt	36,826

The middle row is the whole argument

hic et nunc is not objkt’s contract. It belongs to an earlier Tezos art platform, and objkt indexes it — 771,455 items, still listed, still tradeable through objkt’s interface, ranking among the most active collections on the marketplace today.

That is what “on-chain” actually buys you, demonstrated rather than asserted. The tokens live in a smart contract at a fixed address. A marketplace is an interface onto contracts it did not deploy and does not control. When one interface goes away, the contract does not: another marketplace indexes the same address and the tokens keep working.

It is worth being precise about the limits of that guarantee, because it is routinely oversold.

What the chain holds: ownership, transfer history, and a pointer to the metadata. That part is genuinely durable and not objkt’s to revoke.

What the chain usually does not hold: the image or animation itself. For most Tezos collections the artwork file sits on IPFS, referenced by a content hash. IPFS guarantees that the file matching that hash is the right one — it does not guarantee anyone is still storing it. If every node pinning a piece stops, the pointer remains valid and resolves to nothing.

So the honest formulation: your ownership survives any platform, and your artwork survives as long as someone pins the file. If you collect something you care about, download the asset and pin it yourself. That is the single most useful practical action in this entire category, and almost nobody takes it.

Why the open API matters more than the storefront

A marketplace with a free, unauthenticated GraphQL API is making a structural promise that marketing cannot. It means:

You can verify claims yourself. Collection sizes, holders, sales history, listings — all queryable. You do not have to trust a dashboard.

You can leave. Your collection is not trapped in an interface. Export it, index it, build your own view.

Other interfaces can exist. Alternative front ends, portfolio trackers and archival tools can be built on the same data, which is exactly the resilience the hic et nunc row demonstrates.

objkt also notes a commercial angle for builders: “If you’re building your project on top of the objkt.com API, you can earn a fee for every sale that you refer.” A referral fee for third-party front ends is a sensible way to encourage the ecosystem that makes the data useful.

The practical advice for anyone with more than a passing interest: write the five-line query that lists your own holdings, and run it occasionally. It takes ten minutes and gives you a record independent of any website.

What the documentation does not tell you

Being specific about the gaps, since they affect decisions. The documentation page we read does not state the marketplace fee percentage, does not describe how royalties are enforced, does not say which token standards are indexed, and does not state whether the API has rate limits or requires a key for heavier use.

Those are real omissions for anyone planning either a sale or an integration. Check the fee and royalty terms in the interface before listing, and expect to discover rate limits empirically if you build something that polls.

Where it makes sense to start

Collectors and artists already on Tezos, and developers who want marketplace data without a commercial agreement. The open API is the reason to prefer it as a technical foundation, independent of which front end you enjoy using.

If you are making generative work rather than trading it, fxhash is the publishing platform and has a far more demanding technical contract — code that must render identically forever. More of our coverage of this area is in the media and design archive.

The finding: objkt’s data is open enough that one unauthenticated curl returns the marketplace’s top collections, and among them is a 771,455-item contract objkt did not create — which is the clearest available demonstration that the contract is the asset and the marketplace is just an interface. The caveat that follows is about files rather than ownership: the artwork generally lives on IPFS, so pin anything you would be upset to lose.
