API documentation

Three services, one consistent response. Start with the sample values below.

Make your first request

OpenAPI specification

Create a key in your workspace, then send a JSON request with your key in the Authorization header.

curl -X POST https://lookup.modestambitions.studio/api/v1/ip \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: YOUR_UNIQUE_REQUEST_ID' \
  -d '{"value":"203.0.113.42"}'

Reuse an idempotency key only when retrying the same request. Checks run at most once for that key within your account.

Sample values

Demo mode accepts only these predefined values. It never queries live data.
