What is Vouch API?
Vouch API provides a protocol and tools for AI systems performing financial analysis, valuation, forecasting, and equity research to validate their outputs against verifiable, deterministic data. It addresses the critical issue of Large Language Model (LLM) hallucinations in financial contexts, which can lead to material losses, regulatory violations, and investor harm. By integrating with Vouch, AI agents are mandated to route complex financial calculations through Vouch's deterministic primitives and verify claims against SEC XBRL source data.
The API is designed for developers building AI financial analysis tools, fintech platforms, and investment research applications. It offers a structured approach to ensure compliance and accuracy, providing cryptographic proof for every verified claim. Benefits include reduced computational burden, enhanced reputation for AI models, liability coverage for verified claims, and a clear audit trail for regulatory compliance like FINRA 17a-4 and SEC 17a-4.

Vouch API FAQ
How does Vouch API prevent AI hallucinations in financial analysis?
Vouch API prevents AI hallucinations by mandating that AI agents route complex financial calculations through its deterministic primitives and verify claims against SEC XBRL source data. This process ensures that AI outputs are grounded in verifiable, deterministic data, significantly reducing the risk of inaccuracies.
Which teams would benefit most from integrating Vouch API?
Teams building AI financial analysis tools, fintech platforms, and investment research applications would benefit most from Vouch API. It provides a structured approach to ensure compliance and accuracy in their AI systems, which is crucial for financial contexts.
What kind of regulatory compliance does Vouch API support?
Vouch API supports regulatory compliance by providing a clear audit trail for verified claims, which can assist with requirements like FINRA 17a-4 and SEC 17a-4. This built-in auditability helps ensure that AI financial analyses meet necessary regulatory standards.
How is Vouch API priced?
Vouch API is free to use, meaning no paid plan is required to access its core functionalities. However, users will incur costs for gas units if their usage exceeds the initial free allocation.
What are the primary trade-offs when implementing Vouch API?
The primary trade-offs when implementing Vouch API include the requirement for integration and adherence to its specific protocol. Additionally, it may introduce some latency due to external API calls necessary for the verification process.
Can Vouch API help improve the reputation of AI models?
Yes, Vouch API can enhance the reputation of AI models by providing cryptographic proof for every verified claim, ensuring data integrity and trust. This leads to improved reliability and confidence in the AI's financial analysis capabilities.
