Terms of service

Last updated 2 October 2026.

These terms cover the oassis API at https://oassis.dev and the MCP server at https://oassis.dev/mcp. Using either means accepting them. They are written to be read, not to be survived.

What the service does

oassis fetches web pages and documents you name, converts them, lists and crawls sites you name, drives a browser session on your behalf, and passes a search query to a search provider. It acts on your instructions, as your agent, against the urls you choose.

What you are responsible for

This is the part that matters most, so it is not buried.

• You must have the right to access what you ask for. You are responsible for complying with the terms, licences and access rules of the sites you point us at, and for any law that applies to you or to that content. Asking us to fetch a page does not transfer that responsibility to us, and it does not grant you rights you did not already have.
• robots.txt. Free calls honour it: those requests leave our infrastructure with no account behind them, so they answer to us. Paid calls do not — a paying caller is identified and answers for their own access. If you need robots.txt enforced on your paid traffic, write to us.
• No circumvention. Do not use oassis to defeat a paywall, a login, a rate limit, a block or any other access control, or to collect personal data unlawfully.
• No overwhelming anybody. Including us. Crawls and batches exist so that volume is paced and paid for; do not route around them.

We may refuse or stop a request, and suspend an account, when it breaks these rules. We would rather write to you first, and usually will.

Paying

• Per call, quoted first. The price of a call is in the 402 answer before any work happens, and it is charged after the work happens.
• Work that does not happen is not charged. A request we cannot serve costs nothing, and a crawl or batch you cancel refunds the pages it never read. You do not have to ask.
• A balance does not expire and there is no monthly fee. Prepaid balance is not otherwise refundable.
• Wallet payments are final. A payment settled on a public blockchain cannot be reversed by us. Mistakes are handled as credit, not as a chain transaction.
• Prices can change. The price that applies is the one quoted in the challenge for that call, which is why we quote it on every single one.

What we do not promise

The service is provided as it is. We do not promise an uptime figure, a response time, or that any particular site will be readable — sites change, block automation, or go down, and that is outside our control. We do not promise the content we return is accurate, complete or current: it is what the page said when we read it.

To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability for any claim is limited to what you paid us in the three months before it. Nothing here limits liability that cannot be limited.

Your content and ours

You keep whatever rights you have in what you ask for and what comes back. We claim no ownership of it, and we do not build a corpus out of what our users read — see the privacy policy for what we keep and for how long.

The source code is published under the Elastic License 2.0, which governs the code and not this service. Using the API grants you no licence to the code beyond that.

Ending it

You can stop at any time; there is nothing to cancel. We can suspend or end an account that breaks these terms, and we will refund any unused prepaid balance unless the reason for the suspension was fraud or abuse.

Changes

If these terms change, the date at the top changes with them. A change that materially reduces what you get applies from when it is published, not retroactively.
