build_test — Creates a LiveVariant test and returns every URL needed to run it, plus a freshly generated stats secret.
inspect_test — Decodes a test and describes it: slots, variants, context, and whether it can be served by redirect.
generate_priors — Takes YOUR estimate of how each variant will perform and converts it into the prior the model starts from, so a test does not spend its first visitors rediscovering what you already suspect.
get_stats — Fetches a test's results and works out what they mean.
get_test_status — Reports what the deployment's registry knows about a test: whether it is claimed into an account (and by which organization), and whether each redirect destination is a verified domain.
list_tests — Lists tests registered to the signed-in account, newest first, with cursor pagination and an optional case-insensitive name filter.
register_test — Registers a test you built earlier to the organization a publishable key belongs to, so it shows under My tests and its stats are readable from the dashboard without the secret.
upload_image — Uploads an image to the deployment's asset store and returns its URL, for use as a variant's `image` (email tests) or `url`.
