So the\n  logs are a complete record of names being stood up, with the hour on each. A\n  new api., checkout. or status. is a company building something this week.\n\nA PLATFORM DOMAIN ANSWERS \"WHO JUST JOINED\"\n  A new store gets a certificate for its name under `myshopify.com` like any\n  other tenant, so that question needs no scraper anywhere near the platform.\n  The same works for any hosted product with per-customer subdomains.\n\nA LOOKALIKE IS NOT A MATCH\n  The logs match a substring, which is not what anyone means: a search for\n  `stripe.com` returns `www.online--stripe.com`, somebody else's domain. The\n  boundary is enforced here, so you get `api.stripe.com` and not that.\n\nStudies:\n  search \u003cdomain\u003e\n      certificates issued for names at or under a domain, newest first\n\nJSON to stdout, so it composes: pipe to `jq` to pick a field, or `\u003e /tmp/…` to keep it.\nRun a study with no arguments — `webcertificates search` — to see what it takes.\n","example_command":"webcertificates search acme.com","example_output":"","cost_class":"upstream-fetch","tier":"metered","billing_items":["signals_certificates","signals_certificates_cached"],"price_per_1k_calls":0.6,"price_is_from":true,"status":"available","commands":["webcertificates"],"studies":[{"call":"search","about":"certificates issued for names at or under a domain, newest first","args":[{"name":"domain","positional":true,"list":false,"hint":"a bare domain: acme.com, or a platform's, myshopify.com"},{"name":"since","positional":false,"list":false,"hint":"issued on or after, YYYY-MM-DD"},{"name":"limit","positional":false,"list":false,"hint":"how many certificates"},{"name":"refresh","positional":false,"list":false,"hint":"true | false — read the logs again"}]}],"default_enabled":false,"first_seen":"2026-09-28T05:09:33.097255Z","enabled":false}
