Greptile Search API

  title: Greptile API
  description: >-
    Specification of the Greptile API. Greptile indexes Git repositories into a
    graph plus embeddings, then answers natural-language questions and searches
    over that indexed code. Authentication requires a Greptile API key as a
    Bearer token plus a Git provider token (for GitHub, a GitHub personal access
    token) supplied in the X-GitHub-Token header so Greptile can read the source.

        Queues a Git repository (identified by remote, repository, and branch)
        for processing into Greptile's graph and embeddings. Indexing is
        asynchronous; poll GET /repositories/{repositoryId} until a sha is
        present, which indicates the repository is ready to be queried.
