# API reference > Every public endpoint, with full parameter and response detail. Generated straight from the OpenAPI spec: every request parameter, response field, and status code for each endpoint. For a narrative walkthrough instead, start at [Get started](/) or [Which search endpoint?](/docs/search-endpoints). The core endpoint: run a search and get billed, ranked results back. Shorthand for search with the collection named in the path instead of the body. Same pipeline as search, free, returns teaser rows and an estimated cost. Pays for and returns some or all of a preview call's results. Agentic retrieval: plans its own searches, verifies every candidate. Every collection your key can search, at no cost. Retrieve a prior search's results again for free within 7 days. Daily and monthly query usage against your organization's limits.
