- Worth noticing
- A cap-crossing call returns HTTP 402; worst-case cost is reserved first, with overshoot bounded by one call unless fail-open is enabled.
Field notes
The described flow keeps provider credentials on the proxy and gives clients revocable virtual keys. Google Maps requests are priced by SKU and field mask; the page says reservations run through Valkey before forwarding, with actual costs later replacing them in a Postgres ledger. If Valkey is unavailable, the stated default is to fail closed with a 503, except for keys configured with a small fail-open allowance.
