Quickstart

1. Create an account

Sign in with Google from the top right. There is no password to choose and no card to enter. Your account is created with a welcome grant of credits, plus a free allowance that refreshes on the 1st of every month.

2. Create an API key

Go to API keys and click New key. Give it a label describing where it will be used - "local dev", "production worker", "Claude Desktop" - so you can revoke the right one later.

3. Make a call

Every endpoint is a POST that takes a JSON object and returns JSON. Here is a DNS lookup, which costs one credit:

curl -X POST https://toolkitbackend-j69m.onrender.com/api/v1/tools/dns-lookup \
  -H "Authorization: Bearer tb_live_<your_api_key>" \
  -H "Content-Type: application/json" \
  -d '{"hostname": "example.com", "recordType": "MX"}'

A successful response wraps the result in data, and the headers tell you what it cost:

HTTP/1.1 200 OK
X-Credits-Charged: 1
X-Credits-Remaining: 149

{ "success": true, "data": { "hostname": "example.com", "recordType": "MX", "records": [ ... ] } }

4. Or skip the key entirely

Every endpoint page has a Try it panel that runs the real endpoint using your signed-in session. It costs the same credits but needs no key, so you never have to paste a live credential into a web page just to experiment.
