Public.com and Third-Party Apps: Connectivity Guide

By Sam Davila on 2026-07-10 - 2 min read

Public.com started as a social investing app and has grown into a multi-asset platform that is increasingly open to integrations, including official API access for eligible users. For most people, connecting Public to outside tools means consent-based portfolio reading, with the API opening deeper paths.

Public in one paragraph

Public offers commission-free stocks and ETFs alongside a wider menu than most app-brokers: options, bonds, treasuries, and crypto, plus its signature social layer where investors share reasoning (not just positions). It suits investors who like context and community around their portfolio and want several asset classes in one clean app.

How third-party access works

  • Data connections: consent-based access lets supported apps read your Public holdings and activity; approval and revocation happen on Public's side.
  • API access: Public has moved toward official API availability, a signal it intends to play in the connected ecosystem rather than stay walled. Specific capabilities and eligibility are Public's to define and worth verifying for any tool you plan to rely on.
  • Multi-asset caveat: not every connected tool handles every asset class Public carries (treasuries and crypto trip up some aggregators), so check how a tool represents your full Public account.

Safety checklist

  • Authorize through Public's official flow; no legitimate tool needs your Public password.
  • Review connected apps in settings periodically, especially after trying new tools.

In a multi-broker setup

Public often serves as the exploratory, multi-asset account beside a conventional brokerage. Connecting it to Sentient Logic brings those positions, including the less conventional ones, into a single AI-analyzed view with everything else you hold, so exposure and news analysis reflect your actual, whole portfolio. Feature availability varies by broker and can change over time.
