Terms

Version 1. Effective 25 September 2026.

Agentic Keychain is a product of Vayu Solutions, which operates it. The imprint, linked under Other pages, gives the details.

How a purchase works

1. You evaluate a capability, or ask for a quote, through the site, the API or the MCP endpoint.
2. A person, your operator, completes Polar's checkout page. Outside the United States, Canada and India the price includes VAT or other sales tax; in those three countries the tax is added at checkout. The checkout shows the final amount before you pay.
3. Polar issues the license key with the purchase; it is listed on the purchases page of Polar's customer portal.
4. You send the key to POST /v1/unlock and get a download link that lasts at most 15 minutes. You can unlock again with the same key at any time for a new link; unlocking never charges.

On Polar's checkout page you can review your details and the amount, and correct any input error, before you confirm the purchase. To correct your details afterwards, write to Polar at support@polar.sh.

Polar e-mails you an order confirmation and keeps your order, its invoice or receipt and your license key in its customer portal. The refund policy you bought under stays published at its own address for its version, and each capability version records the SHA-256 of the licence text it is sold under. Save a copy of the licence and the refund policy when you buy.

Buying a capability

• Paid capabilities are sold by Polar Software, Inc. as merchant of record, under Polar's buyer terms: https://polar.sh/legal/checkout-buyer-terms
• A quote is information, not a reservation or payment. Buying needs a person's approval on Polar's checkout page.
• What you may do with a capability you bought is set by its licence, LicenseRef-AK-Paid-Skill. Each version records the SHA-256 of the licence text it is sold under. Licence text: https://agentickeychain.com/licenses/LicenseRef-AK-Paid-Skill/
• Refunds, withdrawal and what happens when a capability is not as described are in the refund policy: https://agentickeychain.com/policies/refunds/v1/
• The licence, the refund policy and these terms are in English.
• We have not signed up to any code of conduct.

Using the registry

• Searching, evaluating and reading capability pages through the site, the API or the MCP endpoint costs nothing. Rate limits apply.
• Evaluations, scores and evidence describe how a capability performed in the tests shown. They are part of what you may expect from it. Your statutory rights as a consumer are not limited by this page or the licence.
• Do not use the registry to overload or attack it or other systems, or to get around its checks.
• If you use the free registry as a business, we are not liable for loss caused by that use, except for loss caused by our intent or gross negligence. If you are a consumer, your statutory rights are not affected.
• Dutch law applies. Consumers keep the protection of the mandatory law of their country of residence.
• We may change these registry terms. A new version applies from its effective date. The licence and refund policy that applied to a purchase do not change for that purchase.

Pricing notice (not part of Terms version 1)

The prices of some capabilities can change, at most once a week per capability. A change applies to every buyer at the same time; no buyer gets a price of their own. You pay the price shown in the checkout you complete. A quote shows the price in force when it was issued and is not binding. A later change does not alter what an earlier purchase cost and does not lead to a refund of any difference; the refund policy applies as it stands.
