Trading just changed forever.. @claudeai is connected directly to a live brokerage through @public API. Research, analysis, and execution now lives inside one conversation. Equities, options, crypto, bonds. Short demo/setup ~10min. Docs link in comments 🦾

Market opens red. Options flow disagrees on 2 names. $AAPL -0.4% → P/C vol 0.13. Pure call buying $GOOGL -1.6% → Heavy calls into a put wall. Clear divergence $SPY put/call OI: 4.65. The hedges are real Built a real-time options sentiment scanner on @Public's API. Every data point - quotes, chains, prev close is live

@skishore1676 @public Good question -historical OHLCV bar data is comparable quality

@BuildwithPublic @public This sounds great, is there parity between polygon and public.com data?

Big update today for @public API: Historical bars and live quotes are now live across the Python SDK, CLI, MCP server, and agent skills. What that means: - Your Python algo gets 5 years of 1-min bars in one call -Your Claude agent sees live quotes before it constructs an order -Your CLI can pull real-time data without touching the app -Your OpenClaw or Perplexity skill is now market-aware The full data + execution stack just got a lot more complete. public.com/api/docs

@TheBottlenecks @joinautopilot @public Means a lot -thank you! The team works hard to earn that and it's great to hear

@joinautopilot @public Been using @public for years. They have a phenomenal team of folks who really go above and beyond. Love it.

Excited to share we’ve partnered with @public to bring Autopilot’s strategies to all Public investors. Anyone with a Public account can now invest in any Autopilot strategy in just a few clicks To celebrate, go open a Public account and get 3 months of Autopilot Premium on us

@RedShouldHawk @public Only equities right now, working on options

@BuildwithPublic @public super cool man. Are you giving us historical intraday options chain pricing for 5 years, did you say in a prior post? Or maybe its only daily ohlc. And this is for equities + indices? Unreal if so!

Volatility breakout strangle this morning on Agents in my @public account Bollinger Band squeeze on $SPY/ $QQQ 5m bars. Volume confirmation. ATM 0DTE strangle on entry. Cut the decaying leg when a candle closes outside the band. Let the winner run. The agent came back and told me exactly what it could and couldn't do - rolling band width calculation, raw volume data, per-leg exit monitoring. Honest and specific, no guessing here. For strategies with stateful intra-session logic, the answer is the API + MCP. Agents handles the simple stuff deterministically. The API handles the complex stuff programmatically. Same account and execution layer- traders now have options that can fit their workflows. That's the stack 🦾

@SandySwings Coming in the near future!

@BuildwithPublic Hi, When can we expect public for International markets please ?

Our builders and traders are RUNNING now🦾

@skishore1676 @public Let’s work on this would be great to have deeper context- will dm you

@BuildwithPublic @public

@252clubb @public We want YOU to take over 🫡

did @public decided to take OVER 2026?

@kovatech_ @public We haven't put too much though into this as API endpoints, but for Agents there is fuctionality that exists now for this case

@BuildwithPublic @public Any plans on adding financials/fundamentals for stocks? I’d be willing to pay extra for that to have all my market data from one source 🙏🏼

@TradeWithSonic @public Right now Public is open to US residents only-are most of these traders located outside the US?

@BuildwithPublic @public Very much interested.. I run a community to traders in SIngapore. who trade QQQ/NQ together. I will start to looking into it from End of May. where do I start?

Built a real-time options flow scanner entirely on the @public API No third-party data vendors.

This is the kind of validation that matters most - a real trader, real tests, real paid data source as the benchmark. Data quality is the foundation everything else is built on. Bad OHLC corrupts your backtest, your signals, and your entries before you ever place a trade. @public is now the data and execution layer

@public Practical use case: your Python strategy pulls historical bars to backtest, switches to live quotes at market open, and routes orders -all through one API key. Or if you're running MCP with Claude, the agent now sees live prices before constructing an order.

@Emmonspired blue sky country feels so good

$ES_F reaching

I'm seeing this more and more every day. Serious traders are done paying for API access when the better platform is free to use and allows them to easily operate with freedom of ideas-> execution with speed Stocks, options(Index+equity), crypto, bonds The migration is happening🦾

@252clubb Smart move. Contract rebate on options, full API access, agents, MCP, CLI - keep the $99/month in your pocket. DM me when you're ready to build your first strategy 🦾

@BuildwithPublic this is actually cool. ill cancel my 99$ alpaca and try public.

Nobody is shipping faster on the trading API front right now. Here's everything we have dropped in the last few months here at @public 👇

The scanner detects institutional positioning in real time. Volume/OI ratio, notional size, OTM conviction, ask-side pressure. When it fires, I can execute directly from the same terminal. One click- no context switching or separate trading platform. That's the structural difference that our API offers builders and traders. We built this so they have the same data infrastructure that institutions take for granted -without the six-figure data subscriptions.

Here's what it takes on @public: -Real-time quotes → Public API -Options chain with greeks → Public API -Order execution → Public API -Historical OHLCV bars up to 5 years → Public API Total cost: $0 in data subscriptions. Rebates on every options contract- zero fee drag
