Short Summary:

Real-time financial auditor for the AI landscape. Resolves live pricing, token-costs, and unit-efficiency for 500+ providers (LLMs, Image, Video).

Full Description:

Sentinel is a production-grade MCP server that gives AI agents "Ground Truth" eyes on the 2026 SaaS economy. While standard LLMs have frozen training data, Sentinel uses semantic search via Exa.ai to fetch current-day pricing.

Core Capabilities:

Unit Normalization: Converts GPU Hours, Credits, and Tokens into a standardized "Cost-per-Generation" metric.

Efficiency Scoring: Automatically calculates the price-per-image or price-per-1M tokens for side-by-side comparison.

Enterprise Ready: Integrated with xPay for secure, metered micropayments and Upstream-Secret protection.

When to use: Use this tool whenever a user asks for the "cheapest," "best-value," or "current price" of any AI tool or developer API.
