Free to integrate. Protected long enough to build.

1. Using Foinse

Foinse earns when value moves: the rail retains 5% of a paid toll in compute. On a separate marketplace purchase, the buyer pays the listed subtotal plus 5% for Base USDC or 5.5% for card processing. The seller receives 100% of the listed subtotal. The supplier sets the toll. A market seller names a listing price and buyers decide whether it clears. Foinse does not price the underlying page, file, endpoint, answer, action, or compute right.

2. The core: Business Source License 1.1

Core technology licensed under the Business Source License 1.1, converting to Apache 2.0 on 2029-09-02.

License effective date: 2026-09-02.

Licensing is file-specific: keyring/ and middleware/ are Apache-2.0; the remaining core code is BSL 1.1; documentation, site copy, the whitepaper, and evidence artifacts are © 2026 Foinse AI LLC, all rights reserved, unless a file states otherwise. The Business Source License 1.1 (BSL 1.1) is source-available, not open source: it grants the right to copy, modify, create derivative works, redistribute, and make non-production use of the work, and it converts to an open license on a fixed date. The parameters in the canonical LICENSE file are:

• Licensor: Foinse AI LLC.
• Licensed Work: Gas Toll (the Foinse compute credit and tolling software), Copyright (c) 2026 James Kelley / Foinse AI LLC.
• Change Date: 2029-09-02.
• Change License: Apache License, Version 2.0.

The Additional Use Grant, verbatim from the license text:

You may use the Licensed Work internally for non-production evaluation, testing, and development purposes. For the avoidance of doubt, this grant does not permit offering the Licensed Work, or any derivative work of it, as a competing tolling, clearing, or key-custody service to third parties.

The quoted grant permits internal, non-production evaluation, testing, and development only; consult the authoritative license for all conditions. The currently published Licensed Work converts to Apache License 2.0 on the Change Date specified in its canonical LICENSE. Later releases may carry their own parameters.

The full license text is authoritative and ships with the code: github.com/Foinse-AI (see the LICENSE file in the canonical repository). Where this page and that file differ, the file governs.

3. The SDKs: Apache License 2.0

The client-side packages, the middleware (the HTTP 402 door for your app) and the keyring SDK (the agent-side wallet), are licensed under Apache License 2.0. Integration is meant to be frictionless: putting the door on your own site does not put your code under the BSL.

4. Trademarks are not licensed

Source availability is not a trademark license. The BSL itself says so expressly. Foinse AI LLC claims FOINSE™ and GAS TOLL™ as trademarks, and no license to the code grants any right to use those names or the associated logos. No trademark license is granted. Applicable law may permit truthful nominative or descriptive use; nothing here restricts rights that cannot lawfully be restricted. You may not brand a deployment, fork, or service in a way that suggests it is Foinse or endorsed by Foinse.

5. Commercial licensing

If you want to operate the Gas Toll core as a commercial service beyond the Additional Use Grant, or you need terms the BSL does not give you, talk to us: hello@foinse.ai.

6. Status

The license parameters summarized here reflect the LICENSE text in the repository. If a parameter changes, the repository file changes first and this page follows it.
