description: 'AdvicePay is a fee-for-service billing, payment processing and engagement-management
  platform built for financial advisors, RIAs and broker-dealers. Founded by Michael Kitces and
  Alan Moore, it lets firms invoice clients for financial planning advice, collect card and ACH
  payments, run recurring subscriptions, capture eSignatures, track engagement workflows and
  deliverables, and enforce compliance oversight over advisor billing. AdvicePay publishes a
  public REST API (v1.0.1) at app.advicepay.com/api/public/v1 covering admins, advisors,
  agreements, clients, custom attributes, deliverables, engagements, invoices, notifications,
  offices, subscriptions and transfers, secured with OAuth 2.0 (authorization code and client
  credentials, with client_secret_post, client_secret_jwt and private_key_jwt authentication
  methods) plus SAML 2.0 single sign-on. API access is an Enterprise-plan capability.'

  description: 'The AdvicePay REST API (v1.0.1) exposes the fee-for-service billing platform to
    integrators: admins, advisors, agreements, clients, custom attributes, deliverables,
    engagements, invoices, notifications, offices, subscriptions and transfers. It is organized
    around resource-oriented URLs, accepts and returns JSON, and uses standard HTTP verbs and
    status codes. Authentication is OAuth 2.0 bearer; a demo environment at demo.advicepay.com
    mirrors production without touching live data or banking networks.'

x-contract-discovery:
  date: '2026-09-09'
  result: no-machine-readable-contract
  detail: >-
    AdvicePay documents 55 REST operations across 13 resources in a fully public, server-rendered
    reference at docs.advicepay.com, but publishes no machine-readable description of any kind.
    The reference is a Slate page whose shape (a Base URLs block, per-operation parameter tables,
    a Schemas section with 44 schemas including a oneOf/xor Pagination union) is characteristic of
    widdershins output, which strongly implies an OpenAPI document exists internally. It is not
    served anywhere reachable. No spec has been generated from the documentation, because a
    contract this pipeline authored would be a fabrication.

    hosts_probed: 5
    result: 404 on every host (403 on the S3-backed docs bucket); no card exists
  - target: soap-wsdl
    result: >-
      No SOAP surface. ?wsdl returns 404 on app.advicepay.com; advicepay.com returns its ordinary
      HubSpot homepage with the query string ignored, which is not a WSDL.
  - target: ogc
    result: not applicable - no geospatial surface and no evidence pointing at one
  - target: asyncapi-webhooks
    result: >-
      No event surface exists. The string "webhook" does not appear anywhere in the reference;
      change notification is polling-only via GET /api/public/v1/notifications.
  docs_host_note: >-
    docs.advicepay.com is a static S3 bucket. It answers 403 AccessDenied for any key that does
    not exist, which is that host's equivalent of a 404 and must not be read as an auth wall.
  provider_fixable: >-
    Publishing the underlying OpenAPI at docs.advicepay.com/openapi.json would be a small change
    with a large effect: it is very likely already generated to build these docs.
