• cheapest The lowest priced rows that meet the given minimums, ranked by estimated monthly USD.
• parse_query See how a sentence would be read, without running it.
• get_server One offer by id with its provider, price history and similar offers.
• compare_servers Up to 20 offers side by side.
• facets Every facet value with its count, under an optional filter set.
• list_providers Hosting providers with their automation (api, cli, terraform, mcp), country, categories and runtimes. Filter with has, country, category, runtime, q.
• get_provider A provider by slug or domain, with every offer it sells here.
• deals Current hosting deals and industry stories.
• stats Counts of servers, providers, countries, GPU offers and the last sync.
• save_search Save a filter set under a name on the caller’s account.
• saved_searches The caller’s saved searches, each with its URL, curl and CLI form.
• delete_saved_search Remove one saved search by id.

• list_invites The caller’s invites (quota, status of each) and open affiliate link. Invites are scarce and single use.
• create_invite Make one invite link from the caller’s quota. The link is returned once; both sides get days of the pass when a new account is made from it.
• list_webhooks The caller’s webhook endpoints (url, event filters, on/off, failures) and the event types r4ck sends: server.listed and server.price_dropped for offers matching
• create_webhook Register an https URL to receive the caller’s events as signed POSTs (CloudEvents body, Standard Webhooks headers). Returns the endpoint and its signing secret
• update_webhook Change an endpoint’s url, events or description, or switch it on/off (switching on clears its failure count).
• delete_webhook Delete an endpoint and its delivery log.
• test_webhook Send a signed webhook.test event to the endpoint now and report the HTTP status.
• rotate_webhook_secret Mint a new signing secret and return it; the old one stops working at once.
