Set API Key

Tachyonic sends prompts to your target via the provider's API. Set the key for your provider:

# Anthropic
export ANTHROPIC_API_KEY=sk-ant-...

# OpenAI
export OPENAI_API_KEY=sk-...

# Google AI
export GOOGLE_API_KEY=AI...

Run a Scan

tachyonic scan \
  --target https://your-api.com/v1/chat/completions \
  --provider anthropic \
  --model claude-haiku-4-5-20251001

Tachyonic sends adversarial prompts to the target and analyzes responses for vulnerabilities.

Scan a Specific Category

tachyonic scan \
  --target https://your-api.com/v1/chat/completions \
  --provider openai \
  --categories prompt-injection,system-prompt-extraction

Limit Attack Count

tachyonic scan \
  --target https://your-api.com/v1/chat/completions \
  --provider anthropic \
  --max-attacks 10

Start a runtime

For longer-running scans against MCP servers or agent stacks, start a runtime — a region-pinned, budget-capped execution with egress controls and approval gates. Drive it from the dashboard or the CLI.

Dashboard:

1. Sign in at platform.tachyonic.co.
2. Go to Runtimes → New Runtime.
3. Pick a target (or paste an endpoint), a region (US or EU), and a budget.
4. Click Start Runtime to start a live runtime, or Create Plan for a dry-run.

CLI:

tachyonic runtime start --target https://your-api.com --region aws-us-east-1

Returns a runtime ID. Follow it to completion with:

tachyonic runtime watch <runtime_id>

The runtime model and full command surface are documented in Runtimes.
