> QWED Finance documentation: deterministic verification for financial AI, banking agents, and payment pipelines, with 11 guards, receipts, and a GitHub Action.

- [QWED Finance: verification for financial AI](https://finance.qwedai.tech/introduction.md): QWED Finance checks what financial AI produces, from NPV and option prices to AML flags, payment messages and SQL, with deterministic code before it is used.
- [Quickstart](https://finance.qwedai.tech/quickstart.md): Install QWED Finance 3.0.1 for Python or Node.js, then check a model's NPV claim and an AML decision in a few lines, with the output you should see.
- [Overview: verification for financial AI](https://finance.qwedai.tech/finance/overview.md): How QWED Finance checks what financial AI produces: the 11 guards, the engines behind them, receipts, and what fails closed before your system acts.
- [The 11 guards for financial AI verification](https://finance.qwedai.tech/finance/guards.md): The 11 QWED Finance guards: Compliance, Calendar, Derivatives, Message, ISO, Query, Cross, Bond, FX, Risk, and Trading, with verified examples for v3.0.1.
- [Design and architecture](https://finance.qwedai.tech/finance/design.md): How QWED Finance is built: the guard modules, the engine each one uses, how receipts are made, and the design rules every check follows.
- [Compliance and auditing](https://finance.qwedai.tech/finance/compliance.md): How QWED Finance makes verification receipts, signs them with your HMAC key for tamper evidence, and keeps an audit log you can export and check later.
- [QWED Finance GitHub Action for CI/CD](https://finance.qwedai.tech/finance/action.md): Verify NPV, IRR, YTM, VaR, and Sharpe calculations in CI with the QWED Finance GitHub Action, including SARIF output for GitHub Advanced Security.
- [Open Responses](https://finance.qwedai.tech/finance/integrations/open-responses.md): Check LLM tool calls in agent loops with QWED Finance: OpenAI-compatible tool schemas, fail-closed handling of unknown tools, and receipts for audit.
- [UCP integration](https://finance.qwedai.tech/finance/integrations/ucp.md): Use QWED Finance with the Universal Commerce Protocol (UCP): payment checks for AI commerce, capability discovery, and receipts for each decision.
