Quick Start

All StackAPIs follow the same authentication and request patterns. Here's a universal example:

curl -X POST https://api.stackapi.dev/api/v1/calculators/mortgage \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"loanAmount": 350000, "interestRate": 6.5, "loanTermYears": 30}'
