Test keys and live keys
wl_test_ keys return fictional data for free; wl_live_ keys return real data and spend credits.
- `wl_test_...`: every endpoint and MCP tool works, returns fictional data on
example.comaddresses, and never spends credits. Responses include"test_mode": true. - `wl_live_...`: real data, and credits are spent only when a result is returned.
Build and test your integration with a test key, then swap in a live key. Nothing else changes.
