Terms of use
onchain data bank · this edition: 17 August 2026
These terms cover onchainbank.com, app.onchainbank.com and the MCP endpoint. They are written plainly and they are short, because the product is measurement and the rules around it are few.
The short version
- Read and use it. Everything published on these hosts is free to read, and the numbers may be used in your own work, including commercial work.
- Cite where it came from. A number of ours travels with the minute it belongs to.
- Do not resell it as a feed and do not train models on it.
- It is not advice. We publish measurements, and what is done with them is yours.
What you may and may not do
| you may | you may not |
|---|---|
| Read every public page, without an account | Crawl the pages or the API in bulk instead of reading the published files and the endpoint we gave you |
| Use the data in internal research, analytics and decision-support systems of your own, including commercial ones | Republish the market state, whole or in bulk, as a data feed of your own, or resell access to it |
| Quote a figure or a whole section with attribution | Present the data as your own measurement, or strip the provenance that qualifies it – the as_of, the revision and the completeness |
| Connect an agent over MCP with a token issued to you, and let it answer your questions from the state | Share that token, or use it on behalf of somebody who was not issued one |
| Cache what you received for as long as your work needs it | Train or fine-tune a machine-learning model on it. The same answer stands in robots.txt – search yes, retrieval yes, training no |
Crawling is not the same as collecting. Search indexing and retrieval crawling in accordance with our robots.txt are permitted, and the signal there says so in three words – index us, quote us, do not train on us. What is not permitted is automated collection intended to reconstruct or republish the dataset.
What the words mean
Four of them decide most questions, so they are defined rather than left to taste.
| word | what it means here |
|---|---|
| Bulk | Taking the published surface wholesale rather than reading it – systematic crawling of the pages, or repeated calls whose purpose is to accumulate a copy of the data rather than to answer a question of yours |
| Feed | Any onward publication of the market state, whole or in part, on a schedule or on demand, to somebody other than yourself – an API, a file drop, a channel, a webhook, a mirror |
| Resale | Charging anyone for access to the data as such, whether directly or as an item inside another price |
| Derived analytics | What you compute FROM the data – a score, a signal, a chart, a conclusion in a report. Derived analytics are yours, and publishing them is allowed, as long as the underlying state is not recoverable from what you publish |
Attribution
Where a figure of ours appears in something published, name the source and the minute it describes:
onchain data bank, ETH market state as of 2026-08-17T09:38Z
The minute is not decoration. Every state carries a fixed as_of and a revision, and a number quoted without them cannot be checked against anything – see how revisions work and how far back each series goes.
Tokens
Access over MCP needs a token, and tokens are issued by hand to a named holder. Using a token is acceptance of these terms. A token is yours alone – it is not transferable, and the holder answers for what is done with it.
We may suspend or revoke a token where these terms are broken, where the load threatens the service for everybody else, or where we are required to. You may ask for your own token to be revoked at any time, and it stops working the moment we do it.
Liability and what we do not promise
- This is not investment advice, not a recommendation and not a signal service. The opinions published on this site are readings of the same measurements, written by a model, and they are marked as such.
- No warranty and no fitness for a particular purpose. The data is served as it is measured, with its completeness beside it.
- Availability is best effort. A venue can go down, a provider can revise, and when that happens the state says so instead of hiding it.
- The service changes. When a definition changes, the methodology version of the state changes with it, so an old answer stays readable under the rules it was written by.
The data is provided as it is measured. To the extent the law allows, we are not liable for indirect or consequential loss, for lost profit, or for any trading or investment decision taken with this data or against it - the decision is yours and so is its outcome. Where liability cannot be excluded, it is limited to the amount you have paid us for the service in the twelve months before the claim.
An agreement of your own comes first
These are the public terms. Where an institutional customer holds a signed agreement with us, that agreement governs, and these terms fill only the gaps it leaves.
Governing law
These terms are governed by the laws of the Cayman Islands, and the courts of the Cayman Islands have jurisdiction over disputes arising from them.
Who publishes this
onchain data bank is the publisher of these pages and of the data behind them. A corporate entity is not named here at the date of this edition, and this page will name one on the day there is one to name.
Questions about these terms, about a use they do not cover, or about access for a team – write to [email protected].
Changes
The date at the top is the edition, and a change takes effect when it is published here. Where a change materially narrows what a token holder may do, we write to the address the token was issued to before it takes effect, and continued use after that is acceptance. Nothing published here applies backwards to work already done under an earlier edition.
