    Derived from artifacts in this repository (conventions/, errors/, rate-limits/,
    authentication/, lifecycle/, data-model/, mcp/). The original specification is
    published by the provider at https://github.com/Fund-z/fundz-api-spec and is never
    mutated — these actions record what API Evangelist established about it.

        Paid plans only on this surface — Pro (50 calls/day) or Strategic (500 calls/day).
        The free instant key belongs to the FundzWatch surface, not to these endpoints.

  update:
    x-apievangelist-auth:
      bearer_prefix: false
      also_accepts: Authorization Bearer <access_token> for ChatGPT/agent integrations (documented, not specified)

      note: >-
        Probed 2026-08-14 — no RateLimit-*, X-RateLimit-* or Retry-After header on any
        response from api.fundz.net. The envelope is the only runtime pacing signal.
- target: $.paths['/products'].get
  update:
    x-apievangelist-operation:
      idempotent: true
      idempotency_key: null
      idempotency_note: GET — idempotent by HTTP semantics; the API publishes no idempotency key.

      incremental_poll: created_from against created_at, newest-first

      undeclared_note: >-
        Documented at https://app.fundz.net/knowledge/api-references/authentication but not
        declared in the specification.

      mcp_note: No FundzWatch MCP tool binds to this operation — see mcp/fundz-tool-crosswalk.yml.
