    ## Authentication


    This API uses OAuth 2.0 for authentication. To get started:


    1. Create an OAuth application at `/oauth/applications`

    2. Get your Client ID and Client Secret

    3. Implement the OAuth 2.0 Authorization Code flow

    4. Use the access token to make API requests


    ## Rate Limits


    - Standard API: 1,000 requests/hour per token

    - Admin API: 10,000 requests/hour per token


    ## Base URL


    All API requests should be made to: `https://api.wefunder.com/api/v2`

      summary: List public offerings
      description: 'Returns the offerings shown on wefunder.com/explore — the curated set of companies that

        meet Wefunder''s discoverability bar (a soft-confirmed traction threshold plus approval),

        **one offering per company**. An "offering" is a fundraise, addressed by its `ofr_`

        external id.


        This is a public, read-only endpoint backed by the `read:public` scope. It is reachable

        with either a server-side (client_credentials) token or a user access token carrying

        `read:public`. Private rounds (e.g. Reg D 506(b)) are never listed, and low-traction or

        unapproved companies are excluded — exactly as they are on the website.


        Order with `sort` (default: most raised); paginate with `cursor`. `meta.total_count` is

        the number of offerings across all pages.


        Use this endpoint to:

        - Discover and monitor active deals

        - Build deal aggregators and public listings
