Billing: AI Gateway's analytics are read with the token that can see them, and a gateway that priced nothing is said1/**
2 * The whole service, on Node, following a repository transfer: a D1 made
3 * of node:sqlite with the service's migrations, the other services as
4 * fakes that answer by method, and Cloudflare's API as a recorded fetch.
5 *
6 * Run with `--experimental-transform-types` (see package.json): the
7 * service's own modules import without extensions, so a resolve hook adds
8 * them.
