Predictefy vs PMXT: The Best PMXT Alternative (2026)
The Short Answer
Predictefy is the best PMXT alternative for anyone building a product, and the deciding line is in PMXT's own pricing page: "All plans are for personal use only." Commercial use of PMXT's hosted API requires a separate sales conversation. Predictefy includes commercial use from its $149 Pro plan upward, serves 16 venues against the 10 PMXT lists, and publishes plans that scale to 3,000 requests a minute and 5 million credits, against PMXT's top published tier of 1,000 requests a minute and 1 million credits. Both start with a free plan of 25,000 credits a month.

Why is Predictefy the best PMXT alternative?
Because PMXT's paid plans are licensed for personal use, and Predictefy's are licensed for the thing you are actually building.
PMXT's pricing page is direct about it: "All plans are for personal use only. Need enterprise access?" followed by a contact link. That applies to its $29.99 Starter plan and its $99.99 Pro plan alike. A startup, a fund, a trading desk or an app with paying users cannot run on those plans without first negotiating separate terms.
Predictefy includes commercial use on Pro and Enterprise, from $149 a month, with no negotiation. The plan you sign up for is the plan you can ship on. For a team building a product, that single difference usually settles the decision before coverage or throughput come into it.
How many venues does each cover?
Predictefy serves 16 venues. PMXT lists 10.
Predictefy's 16 are Gemini, Hyperliquid, Kalshi, Limitless, Myriad, Novig, Opinion, Pascal, Polymarket, Polymarket US, Pred, Predict.fun, PredictStreet, Rain, SX Bet and XO, all on one normalized schema and all reachable at once through a single router path.

-H "Authorization: Bearer pk_live_YOUR_KEY"One call reads every served venue and returns one response shape. Replace router with a single venue id and nothing else changes, so widening or narrowing coverage is a path segment rather than a code change.
How far does each one scale?
Predictefy publishes plans three times higher on request rate and five times higher on credits than PMXT's top published tier.
| Predictefy | PMXT | |
|---|---|---|
| Highest published request limit | 3,000 per minute | 1,000 per minute |
| Highest published monthly credits | 5,000,000 | 1,000,000 |
| Highest published API keys | 10 | Not published |
| Commercial use on published plans | Pro and above | Personal use only |
Predictefy's limiter also runs a fixed 60-second window per API key rather than per account. Two keys on one account each carry the full allowance, so a data scanner and an order path can hold separate budgets. Individual keys can carry a bespoke per-second override when a workload needs it.
What does each cost?
| Predictefy 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 |
Commercial use is included on Pro and Enterprise. PMXT publishes Free at $0 with 25,000 credits, Starter at $29.99 with 250,000 credits and 300 requests a minute, and Pro at $99.99 with 1,000,000 credits and 1,000 requests a minute, all under its personal-use terms.
Predictefy's metering is weighted by what a call does, and every weight is published: 1 credit for metadata, search or a price snapshot, 5 for an order book snapshot or historical query, 10 for cross-venue comparison, price-gap or smart-money analytics, and 15 for an arbitrage query. You pay for the work a call performs, and you can cost a workload before writing it.
What does Predictefy offer that PMXT does not publish?
Cross-venue work as a finished product rather than a set of parts.
PMXT's site describes cross-venue search, matching and smart order routing. Predictefy serves those categories and prices the layer above them as endpoints: price-gap queries at 10 credits, discrepancy qualification at 7, and arbitrage queries at 15, across all 16 venues. It also offers history replay from Builder, unlimited history from Pro, paper trading at 0 credits, conditional orders from Pro, cross-venue portfolio valuation, and an MCP server for agents.
PMXT's open-source SDK can connect to venues directly from your own machine. PMXT's own FAQ notes that "the hosted API requires an API key for cross-venue features like matching and routing," so the cross-venue capability, which is the reason to use an aggregator at all, sits behind the hosted, personal-use plans either way.
Which should you build on?
Predictefy, for any team building something it intends to ship. Commercial use from $149 without a negotiation, 16 venues against 10, published plans reaching three times the request rate and five times the credits, and arbitrage, price-gap and history replay available as priced endpoints. Both offer the same 25,000-credit free plan to start, so the evaluation costs nothing either way.

-H "Authorization: Bearer pk_live_YOUR_KEY"One call, all 16 venues, 15 credits. Results are indicative price discrepancies to assess rather than instructions to trade, and fees, depth and settlement rules still decide which of them survive contact with an order.
