What is Amalgix?

Amalgix is a production-grade document intelligence API powered by the proprietary Crucible™ Engine — a Mixture-of-Agents (MoA) architecture that runs multiple AI models against each other. Hallucinations get caught before they reach you.

• MoA Cross-Verification — multiple models (Gemini Flash, Haiku, Sonnet) independently analyze your document, then a Critic validates every finding against the source text. No single model can hallucinate unchecked.
• Up to 56x cheaper than calling frontier models directly — MoA achieves higher accuracy than any single model while costing less than the cheapest one alone.
• Zero API keys — pay per call with USDC via x402 protocol
• MCP-native + REST API — works with any AI agent or HTTP client

Why Mixture-of-Agents?

Calling a single LLM is fast but unreliable. Every model has blind spots — GPT misses Arabic/Russian data, Gemini drops Chinese entities, Opus hallucinates financial figures. Amalgix solves this with a multi-model Actor-Critic pipeline:

1. Multiple Workers extract findings independently (different models, different perspectives)
2. A cross-provider Critic validates every claim against the original source text
3. A Manager synthesizes verified results into structured, confidence-scored output

The result: 100% accuracy across 10 languages in benchmark tests — something no single model achieves alone. And because MoA uses cost-efficient models (Haiku, Flash) in parallel instead of a single expensive one (Opus, GPT-5.5), it's dramatically cheaper too.

Quick Start

MCP (Recommended)

Add to your MCP client config:

{
  "mcpServers": {
    "amalgix": {
      "url": "https://amalgix.io/mcp",
      "transport": "streamable-http"
    }
  }
}

REST API

curl -X POST https://amalgix.io/api/health_check

All paid endpoints require x402 payment headers. Use estimate_cost (free) to preview pricing before any paid call.

How It Works — Crucible™ MoA Pipeline

                          ┌─ Worker A (Gemini Flash) ─┐
Document → Smart Router → ├─ Worker B (Gemini Flash) ─┼→ Critic (Haiku) → Manager (Sonnet) → Output
              ↓           └─ (parallel extraction)  ──┘    ↓                 ↓
         3-Tier Routing                              Cross-Verify vs     Synthesize +
         (T1/T2/T3)                                  source text       confidence scores

1. Ingest — Document, URL, or raw text up to 20MB. Auto-detected language and format.
2. Smart Routing — 3-tier router selects the optimal pipeline: single-pass (T1), large-context (T2), or chunked MoA (T3).
3. MoA Extraction — Multiple Workers extract findings independently from different angles (breadth vs depth).
4. Cross-Verify (CoVe) — A cross-provider Critic validates every finding against the original source text. Contradictions flagged, hallucinations eliminated.
5. Synthesize — Manager merges verified results into schema-enforced structured JSON with confidence scores.

Pricing

Payment

Amalgix uses the x402 protocol for trustless micropayments:

• Currency: USDC
• Chains: Base (EVM) or Solana (SVM)
• Scheme: exact (both chains — ceiling pre-auth, settle actual price)
• Settlement: Instant, on-chain

No wallet setup required for agents — x402-compatible clients handle payment automatically.

Security & Privacy

• Zero Storage — Documents processed in volatile memory only, never written to disk
• Encrypted Transit — All connections use TLS; no document content in logs
• Third-Party Processing — Content is sent to LLM providers (Google, Anthropic) for analysis
• PII Redaction — Built-in output guard removes sensitive data from responses

⚠️ Do not submit documents containing passwords, private keys, SSNs, or other regulated PII.
