Frequently asked questions

Yes — the desktop app costs nothing on any platform. Data plans (including a Free tier) power what you build; CVForge AI runs on prepaid credits. You can build with your own Claude Code/Codex subscription and the Free data tier without paying cvforge anything.

No. You describe what you want in plain English and the agent writes the app. That said, everything is inspectable — each app is one readable HTML file — so developers can go as deep as they like.

CVForge AI is built in and needs no setup. Claude Code and Codex run embedded with first-class support (auto-detection, scaffolding, MCP wiring, sessions), and OpenCode is supported too. Anything else that runs in a terminal works in the Shell workspace, and anything that speaks MCP can connect with a personal API key.

No. The data is served by ConvexValue’s backend — options snapshots from Massive and 157 Financial Modeling Prep endpoints — with no vendor accounts or keys of your own.

The options snapshot updates continuously and the serving database refreshes about once a minute — built for analytics and monitoring, not trade-by-trade tick analysis. Open interest updates daily after the close (as the exchanges publish it). Massive fair market value is an estimate, not an executable option quote. FMP stock/index quotes and prices are a separate dataset and are delayed; fundamentals update as companies file.

No. cvforge does not provide option bids, asks, quote sizes, midpoint, NBBO, or last trades. The current option snapshot provides Massive’s proprietary fair market value estimate as its only per-contract valuation field. FMV is not an executable quote and should not be used as one.

All listed U.S. equity and ETF options, plus index options (SPX, VIX, NDX, RUT, XSP) — with equities, ETF, and index fundamentals, filings, estimates, and macro data available through the FMP endpoints. Options coverage is U.S. only today.

On your machine, as ordinary files in a folder, with git history. They’re yours: share the HTML file, publish to the gallery, or remix a downloaded app. Nothing you build is locked in cvforge.

The preview sandbox blocks all network access except the local data proxy (plus chart/font CDNs) and disables WebRTC, so a downloaded app can display your data but has nowhere to send it — and it never sees your API key. Still, download from people you trust, and read the HTML if in doubt.

Requests return 429 and the app shows a limit notice. The window resets on the hour. If it happens a lot, the next tier up raises the limit 50x (Free→Go) or 50,000/hour (Research).

Yes — that’s the point of the personal API key (Go and Research): call the REST API from Python, a notebook, a spreadsheet, cron jobs, or point any MCP-capable agent at the MCP server. See the developer API docs.

Your prompts go to whichever agent you chose (your own Claude/OpenAI account for CLI agents, or the AI gateway for CVForge AI). Apps are stored locally and only uploaded if you publish them. Usage telemetry is a toggle in Settings.

They are separate products with different data stacks. The Terminal is a finished professional product for high-fidelity live options analytics. cvforge is a blank canvas plus an agent for research tools built on options snapshots, history, financials, and economics.
