Does PredictFolio have an API?

PredictFolio does not advertise a public API. It is a website.

That matters because "PredictFolio API" is one of the most common searches around the product. People find a useful view of Polymarket traders and want to pull that data into a spreadsheet, a bot, a dashboard or an alert. PredictFolio describes itself as a tool to "discover traders, analyze Polymarket data, compare strategies, and research markets," through its interface.

If what you need is that data as an API, Predictefy is the answer, and it covers more than Polymarket.

curl -s "https://data.predictefy.com/v1/traders/polymarket/markets/MARKET_ID/trades?limit=50" \

Wallet-attributed trades for a Polymarket market: wallet, side, price, amount and USD size on every row. Swap polymarket for Hyperliquid, Limitless, Myriad, Predict.fun, Pascal, XO, PRED or Rain and the same call returns the same shape.

Why is Predictefy the best PredictFolio alternative?

Because it turns trader research into something you can build with, across far more of the market.

Trader analytics across nine venues, not one. Predictefy's Trader Intelligence covers Polymarket, Limitless, Myriad, Hyperliquid, Predict.fun, Pascal, XO, PRED and Rain, with wallet-attributed trade tapes, holders, leaderboards, wallet profiles and versioned smart-money scores where each venue supports them. Smart money does not stay on one venue, and neither should the research.

Market data across sixteen. Beyond trader analytics, Predictefy serves normalized markets, live order books and history for 16 venues, so the question "what did this wallet buy" sits next to "and what is that event priced at everywhere else."

An API, not a page. Everything is available over REST and WebSocket, through TypeScript and Python SDKs, and to agents through an MCP server.

How do you track a portfolio across venues?

With one call. Predictefy's cross-venue portfolio valuation prices positions across venues together, at 10 credits a request.

A Polymarket-only view answers a Polymarket-only question. Most active traders now hold positions on more than one venue, and the useful number is the combined one: total exposure to an event, and what it is worth at current prices wherever it trades.

What does each cost?

Both are free to start. What differs is what free gets you.

PredictFolio is free to use as a website. Predictefy's free plan needs no invite and no card, and carries 25,000 credits a month with API access, trader analytics, market data across 16 venues and trading included. At 10 credits per smart-money or portfolio request and 1 per metadata read, that funds up to 2,500 smart-money queries a month. Paid plans start at $48.88 a month and add bulk endpoints and 12 months of history, with commercial use on Pro.

Which should you use?

Predictefy, the moment you want the data rather than the view. Trader analytics across nine venues, market data across sixteen, portfolio valuation across all of them, and an API, SDKs and MCP server to build on. PredictFolio is a free place to browse Polymarket traders; Predictefy is the platform for building on what they do.
