Why is Predictefy the best PolyRouter alternative?
Because a production system needs a production dependency, with a price you can plan against.
Beta is a real risk for a real product. PolyRouter's documentation describes the service as in "Open Beta" and "free and open to everyone." That is generous for experimentation. It also means the terms, the limits and the price you will eventually pay are not yet published, which is difficult to put in a budget or an investor update.
Predictefy publishes all of it today. Four plans, every credit weight, every request limit, and a commercial-use entitlement from Pro upward. You can cost a workload in a spreadsheet and know it will hold.
More than twice the venues. PolyRouter covers seven platforms. Predictefy serves sixteen: Gemini, Hyperliquid, Kalshi, Limitless, Myriad, Novig, Opinion, Pascal, Polymarket, Polymarket US, Pred, Predict.fun, PredictStreet, Rain, SX Bet and XO.
How many venues does each cover?
Predictefy serves 16 venues. PolyRouter covers 7.

How far does each one scale?
| Predictefy | PolyRouter | |
|---|---|---|
| Service status | Production | Open beta |
| Highest published request limit | 3,000 per minute | 100 per minute, higher on request |
| Published pricing | Four plans, every weight | Free during beta |
| Commercial use | Included from Pro | Not published |
| Client-signed trading | Every plan | Not described |
| Arbitrage and price-gap endpoints | Priced, all 16 venues | Not described |
Predictefy's limiter runs a fixed 60-second window per API key rather than per account, so two keys on one account each carry the full allowance. Individual keys can also carry a bespoke per-second override.
What will each cost in production?
With Predictefy you can answer that today. With PolyRouter you cannot yet.
PolyRouter is free during its open beta and has not published what it will cost afterwards. Predictefy publishes every plan now, so a production budget is a lookup rather than a guess:
| Plan | Monthly | Included credits | Requests/min | API keys | WS streams |
|---|---|---|---|---|---|
| Free | $0 | 25,000 | 60 | 1 | 2 |
| Builder | $48.88 | 500,000 | 300 | 3 | 20 |
| Pro | $149 | 5,000,000 | 3,000 | 10 | 100 |
| Enterprise | From $2,500 | Custom | Custom | Custom | Custom |
Metering is weighted by what a call does: 1 credit for metadata or a price snapshot, 5 for an order book or historical query, 10 for cross-venue comparison or price-gap, 15 for an arbitrage query. The arbitrage feed and bulk endpoints come with every paid plan, and commercial use with Pro and Enterprise.
What does Predictefy add on top of market data?
The layers that turn data into a product.
Predictefy supports client-signed execution, with orders built server side, signed in your own process and relayed, so key custody never moves. It prices cross-venue arbitrage, price-gap and discrepancy qualification as endpoints. It serves wallet-level trader analytics across nine venues, cross-venue portfolio valuation, history replay, paper trading at 0 credits and an MCP server for agents.

-H "Authorization: Bearer pk_live_YOUR_KEY"Every served venue in one call, assessed at a 100-contract size against live asks, for 15 credits. Results are indicative price discrepancies to assess rather than instructions to trade.
