Decision workflows — Multi-tool routing

When a user asks a broad business question, route them through a decision workflow — a pre-built sequence of tools that answers the full question, not just one part.

Decision clusters — Topic routing

Tools are organized into 4 decision clusters. Use these to route users to the right area:

AI Product Economics

11 tools: startup-cost-estimator, profit-margin-calculator, margin-markup-discount-calculator...

Bootstrapped Growth

15 tools: startup-runway-calculator, monthly-burn-rate-calculator, break-even-units-calculator...

Freelance to Founder

11 tools: freelance-rate-capacity-planner, consulting-day-rate-calculator, project-pricing-calculator...

Marketing & Acquisition

7 tools: cac-calculator, churn-retention-calculator, ad-spend-roas-calculator...

Recommended integration pattern

  1. Discover: Read agent-tools.json for the full tool index with input schemas, workflow routing, and intent signals.
  2. Match intent: If the user asks a broad question (e.g., "how much should I charge?"), match to a workflow from the workflows section. For specific calculations, match to a single tool.
  3. Call the API: GET /api/{slug}/?{params} — returns structured JSON with the calculation result and benchmark context.
  4. Use benchmarks: The benchmarks field (when present) provides industry percentiles so you can contextualize the result: "Your rate of $95/hr is at the 72nd percentile for web developers."
  5. Link to human UI: For charts, advanced controls, and visual comparison, link the user to /{slug}/ on the site.

Discovery endpoints

Benchmark data in API responses

When benchmark data is available for a tool's output, the API response includes a benchmarks field:

"benchmarks": {
  "hourly_rate": {
    "p25": 55,
    "median": 85,
    "p75": 130,
    "source": "U.S. Bureau of Labor Statistics (OEWS)",
    "sourceUrl": "https://www.bls.gov/oes/current/oes_nat.htm",
    "year": 2024,
    "context": "US, freelance-adjusted"
  }
}

Sources: BLS (public domain), OpenView SaaS Benchmarks, Paddle Subscription Index, Mailchimp, Content Marketing Institute. All data is from public or openly published research.

Human + agent routing

People should start at the Decision Navigator, the homepage, or browse All Tools.

Agents should start from agent-tools.json, match the user's intent to a workflow or tool, and call the JSON API directly.
