Stork’s verdict on Vouch API

Vouch API provides cryptographic proof for financial claims, but it's likely overkill unless you need institutional-grade certification.

overview

What is Vouch API?

Vouch API is a financial analysis and verification tool developed by VouchAPI that enables PE firms, hedge funds, and AI teams to generate and certify institutional-grade equity research with cryptographic proof. It utilizes SEC XBRL data, DCF valuation, and Monte Carlo simulation with deterministic verification to prevent AI hallucinations in financial analysis. The platform aims to provide deterministic verification for AI systems performing financial analysis, valuation, forecasting, or equity research, addressing risks such as material losses, regulatory violations, and investor harm caused by unverified AI outputs. Vouch API requires AI systems to validate outputs through its "Vouch Truth Anchor" and prohibits direct computation of certain financial metrics, instead mandating the use of Vouch's deterministic primitives. Every financial claim processed must be verified against SEC XBRL source data.

features

Key Features of Vouch API

Vouch API provides a suite of features designed to ensure the accuracy and verifiability of AI-generated financial insights, focusing on cryptographic proof and deterministic verification for critical financial operations.

  • Generates institutional-grade equity research.
  • Certifies correctness of financial outputs with cryptographic proof.
  • Utilizes SEC XBRL data for source verification of financial claims.
  • Performs Discounted Cash Flow (DCF) valuation with deterministic verification.
  • Employs Monte Carlo simulation with deterministic verification for risk analysis.
  • Provides an API for integration into existing financial analysis workflows.
  • Validates AI system outputs across financial analysis, valuation, forecasting, and equity research.
  • Offers a cryptographically-signed Decision Object, including a full audit trail and evidence links.
  • Ensures regulatory compliance with standards such as FINRA 3110 and SEC 17a-4.
  • Provides $10,000,000 liability coverage per verified claim.
  • Establishes cryptographic identity for AI agents to prove actions and intent.

use cases

Who Should Use Vouch API?

Vouch API is primarily designed for financial institutions and AI development teams that require high levels of accuracy, verifiability, and compliance in their financial analysis and research processes, particularly when leveraging AI.

  • PE firms: For reducing diligence cycles (e.g., from 12 days to 36 hours) and generating auditable investment research with cryptographic audit trails for closing objections.
  • Hedge funds: For increasing coverage without additional headcount and enabling AI agents to produce auditable thesis statements with verifiable citations.
  • AI teams: For validating AI system outputs in financial analysis, valuation, forecasting, or equity research, and establishing cryptographic identity for AI agents to mitigate risks like HIPAA violations or unauthorized financial trades.
  • Organizations requiring compliance: For generating audit trails compliant with FINRA 3110 and SEC 17a-4, ensuring regulatory adherence for financial claims and AI agent actions.

pricing

Vouch API Pricing & Plans

Vouch API operates on a freemium model with tiered access to its API and a usage-based cost for verified LLM output, structured around 'Trust Credits'. The cost per 1k tokens of verified LLM output varies based on the enterprise bundle purchased.

  • PROBATIONARY: Free, includes an API rate limit of 100 requests per hour.
  • VERIFIED: Contact for pricing, includes an API rate limit of 1000 requests per hour.
  • TRUSTED: Contact for pricing, includes an API rate limit of 10000 requests per hour.
  • Verified LLM Output: From $1.00 to $2.00 per 1k tokens. This pricing is based on 1 Trust Credit (TC) per 100 tokens of verified LLM output. The cost per TC varies by enterprise bundle: Systemic Pack ($0.1/TC), Platform Pack ($0.125/TC), Enterprise Pack ($0.17/TC), Growth Pack ($0.2/TC). Therefore, 10 TC (for 1k tokens) would range from $1.00 to $2.00.

Vouch API vs Competitors

Vouch API positions itself as a specialized solution for preventing AI hallucinations in financial analysis by offering deterministic verification with cryptographic proof. This differentiates it from other AI financial tools that may focus on broader analysis, direct source linking, or multi-agent frameworks.

1
FinRobot↗

FinRobot is the first AI agent framework specifically designed for equity research, employing a multi-agent Chain of Thought (CoT) system for comprehensive quantitative and qualitative analysis.

FinRobot focuses on blending discretionary judgment with quantitative analysis and real-time data for sell-side research, similar to Vouch API's institutional-grade output, and explicitly uses DCF models. While Vouch API emphasizes cryptographic proof, FinRobot highlights its multi-agent CoT system for accuracy and realistic risk assessments.

Anthropic (Claude's Financial Analysis Solution)On Stork

Claude's Financial Analysis Solution provides verifiable answers by linking every claim directly to its original source for transparency, and it excels in complex analysis including Monte Carlo simulations.

Similar to Vouch API, Claude's solution offers verification and Monte Carlo simulations for financial analysis. Vouch API specifies cryptographic proof, while Claude emphasizes direct source linking for transparency and error reduction.

3
Fiscal.ai↗

Fiscal.ai is an AI-powered investment research platform that provides institutional-grade financial data, analytics, and conversational AI within an all-in-one fundamental research terminal and API solution.

Fiscal.ai offers a comprehensive platform for fundamental research with high-quality global financial data and APIs, similar to Vouch API's data-driven approach. While Vouch API focuses on cryptographic proof and specific valuation methods, Fiscal.ai emphasizes efficient research, understanding key performance indicators, and modernized workflows.

4
Marvin Labs↗

Marvin Labs distinguishes itself with a source verification architecture, ensuring every AI-generated insight links directly to a specific passage in a source document to prevent hallucinations.

Marvin Labs, like Vouch API, aims for high accuracy in institutional research by providing source-verified AI output, directly addressing the 'hallucination' concern in AI. While Vouch API uses cryptographic proof for correctness, Marvin Labs focuses on direct document citation for verification.
