Why Amalgix?

AI agents that need evidence-backed facts from financial filings and contracts face a problem: calling frontier models like Opus 4.8 or GPT-5.5 is expensive, and a single call doesn't produce verified evidence — you need at least two passes (extract + verify) to get source-grounded output.

Amalgix solves this with a cross-model evidence pipeline:

1. Model A extracts — A specialized extraction model pulls structured findings from your document. Each claim is tied to a verbatim quote, confidence score, and source reference.
2. Model B verifies — A different model cross-checks every finding against the original source. Contradictions are flagged; unsupported claims are marked for review — not presented as facts.
3. You pay less — Because each stage uses the optimal model for the job (not the most expensive one), the total pipeline cost is significantly lower than running frontier models yourself.

Cost Comparison (1MB Document)

Provider	Pipeline Cost	vs Amalgix
Amalgix	$0.82	—
Opus 4.8 (2-pass)	$2.88	3.5x more
GPT-5.5 (2-pass)	$3.12	3.8x more

Competitor costs represent what it takes to replicate Amalgix's extract → verify output using those models directly (2-pass, ~15% + ~10% output ratio).

What is Amalgix?

A crypto-native, MCP + REST intelligence API for AI agents. The proprietary Crucible™ Evidence Engine orchestrates the cross-model pipeline:

• Source-grounded claims — each material finding includes claim, evidence, sourceRef, confidence, and verificationStatus
• Cross-model verification — extraction and verification use different models, catching errors that single-model approaches miss
• Financial Filing Intelligence — SEC 10-K, 10-Q, and 20-F analysis by content, filing URL, ticker, or CIK
• Contract Risk Intelligence — clauses, obligations, deadlines, liability, missing terms, and evidence
• x402 payments — paid calls settle in USDC on Base or Solana. No API keys required, no subscriptions
• Wallet dashboard — EVM wallet login for request history and API key management

Crucible is designed for evidence triage and agent workflows. It does not claim perfect accuracy, legal advice, or investment advice; responses expose confidence and verification metadata so downstream systems can inspect the basis for each finding.

Quick Start

MCP

Add Amalgix to any Streamable HTTP MCP-compatible client:

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

REST

curl -X GET https://amalgix.io/api/v1/health

Paid endpoints require x402 payment headers. Use estimate_cost first to preview pricing before any paid call.

Crucible™ Output Contract

Crucible normalizes evidence into a stable shape for agents:

{
  "analysis": {
    "summary": "...",
    "evidenceFindings": [
      {
        "claim": "...",
        "evidence": "...",
        "sourceRef": "document:line:12",
        "confidence": "high",
        "verificationStatus": "supported"
      }
    ],
    "overallConfidence": "high"
  },
  "meta": {
    "engine": "Crucible™ Evidence Engine",
    "analysisType": "general_evidence",
    "routingTier": "large_context",
    "estimatedCost": 0.03
  }
}

Analysis modes:

• general_evidence
• financial_filing
• contract_review

Pricing

Dynamic pricing based on document size. Amalgix's cross-model pipeline delivers equivalent evidence quality at a fraction of single-model cost:

File Size	Amalgix	Opus 4.8 (2-pass)	GPT-5.5 (2-pass)	Savings
256KB	$0.30	$0.76	$0.82	59-62%
1MB	$0.82	$2.88	$3.12	72-74%
5MB	$7.36	$12.12	$13.14	39-44%
20MB	$29.42	$46.52	$50.50	37-42%

Use the free estimate_cost tool for a request-specific quote.

Payment

Amalgix uses the x402 protocol for pay-per-call settlement:

• Currency: USDC
• Chains: Base (EVM) or Solana (SVM)
• Scheme: exact
• Authentication: x402 for paid execution; optional wallet/API key identity for dashboard and REST attribution

Security & Privacy

• Contract raw text is not persisted by default; Amalgix stores hashes, metadata, job status, and optional results only when configured.
• Public financial filing metadata may be cached because filings are public.
• Connections use TLS.
• Paid analysis content is sent to third-party LLM providers for processing.
• Do not submit passwords, private keys, SSNs, classified data, or other regulated PII.
• Contract and filing outputs are evidence triage only, not legal or investment advice.
