           TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
        
           1. Definitions.
        
              "License" shall mean the terms and conditions for use, reproduction,
              and distribution as defined by Sections 1 through 9 of this document.
        
              "Licensor" shall mean the copyright owner or entity authorized by

              other entities that control, are controlled by, or are under common
              control with that entity. For the purposes of this definition,
              "control" means (i) the power, direct or indirect, to cause the
              direction or management of such entity, whether by contract or
              otherwise, or (ii) ownership of fifty percent (50%) or more of the
              outstanding shares, or (iii) beneficial ownership of such entity.
        
              "You" (or "Your") shall mean an individual or Legal Entity
              exercising permissions granted by this License.
        
              "Source" form shall mean the preferred form for making modifications,
              including but not limited to software source code, documentation
              source, and configuration files.
        
              "Object" form shall mean any form resulting from mechanical
              transformation or translation of a Source form, including but
              not limited to compiled object code, generated documentation,
              and conversions to other media types.
        
              "Work" shall mean the work of authorship, whether in Source or
              Object form, made available under the License, as indicated by a
              copyright notice that is included in or attached to the work
              (an example is provided in the Appendix below).
        
              "Derivative Works" shall mean any work, whether in Source or Object
              form, that is based on (or derived from) the Work and for which the
              editorial revisions, annotations, elaborations, or other modifications
              represent, as a whole, an original work of authorship. For the purposes
              of this License, Derivative Works shall not include works that remain
              separable from, or merely link (or bind by name) to the interfaces of,
              the Work and Derivative Works thereof.
        
              "Contribution" shall mean any work of authorship, including
              the original version of the Work and any modifications or additions
              to that Work or Derivative Works thereof, that is intentionally
              submitted to Licensor for inclusion in the Work by the copyright owner
              or by an individual or Legal Entity authorized to submit on behalf of
              the copyright owner. For the purposes of this definition, "submitted"
              means any form of electronic, verbal, or written communication sent
              to the Licensor or its representatives, including but not limited to
              communication on electronic mailing lists, source code control systems,
              and issue tracking systems that are managed by, or on behalf of, the
              Licensor for the purpose of discussing and improving the Work, but
              excluding communication that is conspicuously marked or otherwise
              designated in writing by the copyright owner as "Not a Contribution."
        
              "Contributor" shall mean Licensor and any individual or Legal Entity
              on behalf of whom a Contribution has been received by Licensor and
              subsequently incorporated within the Work.
        
           2. Grant of Copyright License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              copyright license to reproduce, prepare Derivative Works of,
              publicly display, publicly perform, sublicense, and distribute the
              Work and such Derivative Works in Source or Object form.
        
           3. Grant of Patent License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              (except as stated in this section) patent license to make, have made,
              use, offer to sell, sell, import, and otherwise transfer the Work,
              where such license applies only to those patent claims licensable
              by such Contributor that are necessarily infringed by their
              Contribution(s) alone or by combination of their Contribution(s)
              with the Work to which such Contribution(s) was submitted. If You
              institute patent litigation against any entity (including a
              cross-claim or counterclaim in a lawsuit) alleging that the Work
              or a Contribution incorporated within the Work constitutes direct
              or contributory patent infringement, then any patent licenses
              granted to You under this License for that Work shall terminate
              as of the date such litigation is filed.
        
           4. Redistribution. You may reproduce and distribute copies of the
              Work or Derivative Works thereof in any medium, with or without
              modifications, and in Source or Object form, provided that You
              meet the following conditions:
        
              (a) You must give any other recipients of the Work or
                  Derivative Works a copy of this License; and
        
              (b) You must cause any modified files to carry prominent notices
                  stating that You changed the files; and
        
              (c) You must retain, in the Source form of any Derivative Works
                  that You distribute, all copyright, patent, trademark, and
                  attribution notices from the Source form of the Work,
                  excluding those notices that do not pertain to any part of
                  the Derivative Works; and
        
              (d) If the Work includes a "NOTICE" text file as part of its
                  distribution, then any Derivative Works that You distribute must
                  include a readable copy of the attribution notices contained
                  within such NOTICE file, excluding those notices that do not
                  pertain to any part of the Derivative Works, in at least one
                  of the following places: within a NOTICE text file distributed
                  as part of the Derivative Works; within the Source form or
                  documentation, if provided along with the Derivative Works; or,
                  within a display generated by the Derivative Works, if and
                  wherever such third-party notices normally appear. The contents
                  of the NOTICE file are for informational purposes only and
                  do not modify the License. You may add Your own attribution
                  notices within Derivative Works that You distribute, alongside
                  or as an addendum to the NOTICE text from the Work, provided
                  that such additional attribution notices cannot be construed
                  as modifying the License.
        
              You may add Your own copyright statement to Your modifications and
              may provide additional or different license terms and conditions
              for use, reproduction, or distribution of Your modifications, or
              for any such Derivative Works as a whole, provided Your use,
              reproduction, and distribution of the Work otherwise complies with
              the conditions stated in this License.
        
           5. Submission of Contributions. Unless You explicitly state otherwise,
              any Contribution intentionally submitted for inclusion in the Work
              by You to the Licensor shall be under the terms and conditions of
              this License, without any additional terms or conditions.
              Notwithstanding the above, nothing herein shall supersede or modify
              the terms of any separate license agreement you may have executed
              with Licensor regarding such Contributions.
        
           6. Trademarks. This License does not grant permission to use the trade
              names, trademarks, service marks, or product names of the Licensor,
              except as required for reasonable and customary use in describing the
              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions
              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
              PARTICULAR PURPOSE. You are solely responsible for determining the
              appropriateness of using or redistributing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,
              and charge a fee for, acceptance of support, warranty, indemnity,
              or other liability obligations and/or rights consistent with this
              License. However, in accepting such obligations, You may act only
              on Your own behalf and on Your sole responsibility, not on behalf
              of any other Contributor, and only if You agree to indemnify,
              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.

Give AI agents safe, bounded web intelligence without subscriptions, API keys or handing a crawler
unrestricted network access. Start with three free MCP tools; pay only for the URL operation used.
Production uses x402 v2, Base Mainnet USDC and PayAI.

Try the real safe fetch path in one command — fixed `example.com`, no payment:

```bash
curl -sS https://1cent.maxzoa.ru/v1/demo/live-pulse
```

Or preview one URL of your choice without payment, limited to one preview per client and UTC day:

```bash
curl -sS "https://1cent.maxzoa.ru/v1/demo/preview?url=https%3A%2F%2Fexample.com%2F"
```

- MCP: `https://1cent.maxzoa.ru/mcp`
- Free product demo: `https://1cent.maxzoa.ru/v1/demo/pulse`
- Free live demo: `https://1cent.maxzoa.ru/v1/demo/live-pulse`
- Live catalog/prices: `https://1cent.maxzoa.ru/v1/catalog`
- Public trust status: `https://1cent.maxzoa.ru/status.json`
- Buyer guide: `https://1cent.maxzoa.ru/docs/getting-started`
- Browser purchase entry: `https://1cent.maxzoa.ru/try`
- Outcome packages: `https://1cent.maxzoa.ru/v1/products`

Production exposes 32 paid REST/MCP operations plus three free MCP tools:

- `catalog.tools.search` — find the correct operation and live price without a URL fetch;
- `demo.url.pulse` — inspect a fixed precomputed output sample without payment or network access.
- `demo.live.pulse` — run the real safe service against fixed `example.com`, rate-limited.

Public MCP discovery uses navigable dot-notation (`web.url.status`, `web.site.openapi`). Pre-0.6
underscore names remain accepted as compatibility aliases but are intentionally omitted from
`tools/list`.

MCP also publishes one buyer prompt (`choose_url_tool`) and one static buyer-guide resource
(`onecent://buyer-guide`). Every input field includes constraints, examples and machine-readable
descriptions so agents can choose and call tools correctly on the first attempt.

## Find 1cent

- Official MCP Registry: `ru.maxzoa/1cent`;
- Glama remote connector: `https://glama.ai/mcp/connectors/ru.maxzoa/1cent`;
- Smithery: `https://smithery.ai/servers/maxzoa27/onecent`;
- MCP.so: `https://mcp.so/servers/1cent`;
- LobeHub: `https://lobehub.com/mcp/maxzoa-1cent`.
- MCPServers.org: `https://mcpservers.org/ru/servers/maxzoa/1cent`.

Glama release verification uses the repository's `onecent-glama` stdio entry point. It loads the
same MCP tool registry as production for schema inspection; it does not provide a payment bypass
or a second implementation of paid URL operations.

Directory status is checked with dated evidence in
[Marketplace quality report](MARKETPLACE_QUALITY_062_REPORT.md). A page returning HTTP 200 alone is
not counted as a successful listing: it must be searchable, current and installable.

Buyer setup starts with a no-payment diagnostic:

```bash
onecent doctor
```

Generate or install a secret-free MCP client configuration:

```bash
onecent install --client claude
onecent install --client cursor --apply
onecent install --client vscode --apply
onecent install --client codex
```

For MCP clients without native x402 signing, install the local Buyer Bridge:

```bash
pipx install "onecent[buyer] @ git+https://github.com/maxzoa/1cent.git"
onecent wallet set
onecent bridge --max-usdc-per-call 0.001 --daily-limit-usdc 0.01
```

Manual one-call approval is the default. The OS keyring holds the buyer secret; 1cent, remote MCP
and catalog services never receive it. UNKNOWN outcomes are never retried. See
[Buyer Bridge](BUYER_BRIDGE.md) for Claude, Cursor, VS Code and Codex setup.

The direct CLI also refuses a paid call unless the buyer explicitly supplies a maximum amount,
confirms Base Mainnet and types the one-call confirmation. See `examples/buyer-python` and
`examples/buyer-node`.

Node buyers can use the release package in `packages/onecent-buyer`:

```bash
cd packages/onecent-buyer
npm ci
npm exec -- onecent-buyer doctor
```

`onecent watch` provides finite, capped change monitoring. It is disabled by default, requires
explicit Base network/asset/seller confirmations and stops on UNKNOWN without creating a new
payment attempt.

PostgreSQL is the runtime source for tool availability and atomic Base USDC prices. Config
values are clean-install fallbacks. Paid URL work begins only after successful payment checks.

## Safety contract

- public HTTP/HTTPS only; private, loopback, link-local and rebinding destinations fail closed;
- strict input schemas; unknown fields rejected;
- bounded redirects, response bodies, extracted text, concurrency and queue depth;
- payment identifier, request fingerprint and idempotent replay protection;
- UNKNOWN settlement never retried automatically;
- no seller private key, buyer key, Docker socket or JavaScript execution on the server;
- Streamable HTTP host/origin protection enabled for remote MCP.
- optional signed x402 offers and settlement receipts use a dedicated Ed25519 `did:web` key;
  they never expose or reuse a buyer or seller private key.

## Local quality checks

```bash
python -m venv .venv
.venv/Scripts/pip install --require-hashes -r requirements-dev.lock
.venv/Scripts/pip install --no-deps -e .
ruff check .
mypy
pytest -q
python scripts/validate_release.py
docker compose --env-file .env.example config
docker compose --env-file .env.example build
pip-audit --no-deps -r requirements.lock --progress-spinner off
```

## Local Docker start

Copy `.env.example` to `.env`, replace placeholders, keep `X402_ENVIRONMENT=testnet` and
`X402_NETWORK=eip155:84532`, then:

```bash
docker compose up -d --build
docker compose ps
```

Container UID/GID: `10001:10001`. No host bind-mounted writable directory is required.
This local example is intentionally testnet. Production mainnet activation requires owner approval,
a fresh PostgreSQL backup, production preflight, development bypass disabled and rollback readiness.
