Getting Started

From zero to first call
in two minutes.

Three steps. No card. Free forever for 500 calls / month.

1. Create your account

Head to /signup and continue with Google. You'll land in the dashboard with an empty key list.

2. Generate an API key

From Dashboard → API Keys, click Generate key. Give it a label (e.g. “Production”, “Notebook”). The full secret is shown exactly once— copy it now. We only store a SHA-256 hash.

Your new key (shown once)

3. Make your first call

Call any tool with POST /v1/{domain}/{slug}. The body is JSON; pass each input by its key.

curl · execute pcb-trace-width

curl -X POST https://api.toolsamurai.com/v1/pcb-design/pcb-trace-width \
  -H "Authorization: Bearer sk_free_•••••••••••••••" \
  -H "Content-Type: application/json" \
  -d '{"current_a": 3.5, "temp_rise_c": 10, "copper_weight_oz": 1, "layer": "outer"}'

What you get back

Every response is wrapped in the standard envelope — ok, tool, domain, version, result, meta:
