When the CFO asks "where's the money going?" and the board wants AI ROI, you'll have the answer. Track every call, every token, every dollar across all your AI systems.

  • Cost attribution by team, workflow, and model
  • Complete audit trail for compliance
  • Works with OpenAI, Anthropic, Groq, Gemini, and more

What's happening without observability

  • Runaway costs: OpenAI bill went from $2K to $15K. Nobody knows why.
  • Zero attribution: 14 teams using AI. Which ones deliver ROI?
  • No prompt history: Someone changed a prompt. Conversions tanked. No record.
  • Audit nightmare: Compliance asks for AI logs. You have a vague CSV.

Built For

The People Who Get Asked "Where's the Money?"

Jennifer

The CFO

"AI spend grew 400% with zero attribution."

  • Cost by team, model, and workflow
  • Department-level budgets and alerts
  • ROI dashboards and chargebacks

Robert

The Risk Officer

"Show me an audit trail of every AI response."

  • SHA-256 hashed logs
  • Export to BigQuery, CSV, or SIEM
  • Retention controls and deletion

David

The CTO

"14 teams, 4 providers, zero visibility."

  • Centralized proxy for all providers
  • Dual-key authentication
  • Prompt version history

Lisa

The Data Scientist

"I'm eyeballing outputs because nobody gave me eval tools."

  • BigQuery-native analysis
  • Custom metadata and labels
  • Drift detection (roadmap)

Complete Visibility

Every Call. Every Token. Every Dollar.

Live Stream

Every request/response with prompt, completion, tokens, latency, user, workflow, and custom metadata.

Cost Attribution

Real-time spend by team, model, and workflow. Alerts when costs spike. Per-department budgets.

Prompt Versioning

Track changes, compare performance, replay conversations. Know what changed and when.

Compliance Ready

SOC 2 controls, hashed transcripts, export APIs, and deletion workflows tied to user IDs.

Integration = Change One URL

If you can find-and-replace, you can install Demeterics. No SDK, no code changes, no deployment.

  1. Replace your base URL.
    api.openai.com → api.demeterics.com/openai/v1
  2. Add your Demeterics key.
    Use combined auth or dual-key for Zapier/Make.
  3. Send metadata.
    Add x-dem-app, x-dem-flow headers for attribution.
See the Quick Start Guide 
curl https://api.demeterics.com/groq/v1/chat/completions \
  -H "Authorization: Bearer YOUR_DEMETERICS_KEY" \
  -H "x-dem-app: marketing" \
  -H "x-dem-flow: lead-gen" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "your-model-name",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Works with Zapier, Make, n8n, LangChain, Vercel AI SDK, and any HTTP client.

Dual-Key Authentication

Separate automation access from admin control. Zapier gets a proxy key. Humans keep the admin key. Both required for requests.

Why CTOs care: Even if a low-code tool is compromised, attackers can't drain your data or credits.

// Automation key (Zapier, Make, n8n)
dem_live_automation_xxx

// Admin key (humans + governance)
user_live_admin_yyy

// Request requires both
Authorization: Dual dem_live_automation_xxx:user_live_admin_yyy
