Capitalist Payments API (v1, deprecated)

The first generation of the Capitalist API: a single HTTP POST endpoint at https://api.capitalist.net where an `operation` form field selects the call (get_accounts, import_batch_advanced, process_batch, currency_rates, documents_search, get_batch_info, get_document_fee, get_documents_history_ext, get_token, is_verified_account). Credentials travel as form fields — account login plus a plain, encrypted or certificate-signed password. Capitalist has moved its documentation to https://capitalist.net/developers/deprecated/v1/api; the host still answers and self-reports API version 1.9.8, but no sunset date is published.

OpenAPI Specification

openapi: 3.2.0
info:
  title: Capitalist Payments API
  description: 'Capitalist Payments API for mass payouts, accounts, currency conversion,

    and document history. The API is a single HTTP/1.1 POST endpoint at

    https://api.capitalist.net/ where the operation is selected via the

    `operation` form field. Requests may be sent as

    application/x-www-form-urlencoded or multipart/form-data and must

    include a Capitalist username and password (or a "Plain password" or

    encrypted-certificate signature) plus an optional response format

    selector.


    This specification is a best-effort, hand-authored representation of

    the publicly documented operations at

    https://capitalist.net/developers/api. Detailed operation parameters

    and response payloads are documented per-operation by Capitalist; this

    file models the high-level operation envelope.
