Summary
This is a dual-endpoint marketplace for AI training data built on museum collections. The Data Portal MCP exposes 13 tools for searching 2M+ artworks across the Met, Rijksmuseum, Smithsonian and others, then enriching them with 111-field VLM metadata called Golden Codex. The Fluora MCP handles x402 USDC micropayments on Base L2 for AI agents, while humans pay via Stripe. Tools include search_alexandria for browsing, get_oracle_metadata for deep VLM analysis at $0.16 per record, and enrich_agent_image to process your own images through the same pipeline. Reach for this when you need densely annotated art datasets with commercial metadata rights, not just CC0 image access.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Intelligence Aeternum MCP
AI training dataset marketplace exposed as MCP servers. 2M+ museum artworks across 7 world-class institutions with on-demand 111-field Golden Codex AI enrichment. AI agents pay with x402 USDC on Base L2. Human buyers pay with Stripe.
Quick Start
Connect to the MCP endpoint with any MCP-compatible client:

Payment
Two payment paths -- one marketplace, two buyer types:
- AI agents pay with x402 USDC micropayments on Base L2. No API keys, no subscriptions -- agents pay autonomously per request.
- Human buyers pay with Stripe checkout. Credit/debit cards, Apple Pay, Google Pay -- standard web checkout for dataset purchases and enrichment orders.
x402 Flow (AI Agents)
- Call a paid tool without payment
- Receive HTTP 402 with x402 payment envelope
- Execute USDC transfer on Base L2
- Re-call with
X-PAYMENTheader containing transaction proof - Receive data

Research
Our peer-reviewed paper The Density Imperative demonstrates that dense metadata significantly impacts VLM capability:
- +25.5% improvement with 111-field Golden Codex enrichment
- -54.4% degradation with sparse 10-20 word captions
- +160% semantic coverage vs raw captions

Important: What You're Paying For
Pricing applies to structured AI training metadata only -- not the source images. All 2M+ source artworks are CC0/public domain from partner museums and freely available from their original APIs. What Intelligence Aeternum provides is:
- Golden Codex enrichment: 111-field NEST metadata generated by multi-model VLM analysis (Gemini + Claude + GPT-4o)
- Compliance manifests: Auto-generated AB 2013 + EU AI Act Article 53 documentation
- Pipeline services: Upscaling, metadata infusion, C2PA signing, hash registration, permanent storage
- Structured datasets: Pre-enriched collections optimized for AI training workflows
License
Source code in this repository is provided for reference and transparency. The enrichment metadata, Golden Codex schema, and pipeline services are proprietary to Metavolve Labs, Inc. Source images from museums are CC0/public domain.
