Question 1

Can I upgrade from Dev to Pro?

Accepted Answer

Yes. You can upgrade from any plan at any time and your new limits take effect immediately. If you downgrade, you keep your current tier's features until your billing period ends.

Question 2

Do you offer a free trial for Pro?

Accepted Answer

You can start with the Free tier to explore the API — no credit card required. If you're considering a deeper integration and want to evaluate which plan is right for you, or have custom needs, schedule a call with us and we'll help you find the right fit.

Question 3

What payment methods do you accept?

Accepted Answer

All major credit cards through Stripe. All payments are secure and encrypted.

Question 4

What does Enterprise priority routing include?

Accepted Answer

Enterprise customers get dedicated node infrastructure with priority routing. This means lower WebSocket latency through direct node access — the fastest data feeds available.

Question 5

What happens if I exceed my rate or quota limits?

Accepted Answer

API requests beyond your rate limit will receive a 429 response. On the Free plan, hitting your 1,000 monthly quota is a hard stop. On Dev, the first 1M requests are included, then $5 per 100K after. On Pro, the 5M monthly limit is a soft quota with $2.50 per 100K requests beyond it. Note: historical data endpoints (trades, orderbooks, wallet-level market activity) are unlimited on all plans and do not count toward your monthly quota. Upgrade to a higher tier for increased limits.

Question 6

Is historical data really free on all plans?

Accepted Answer

Yes. All historical data endpoints — including trades, orderbooks, and wallet-level market activity — are completely free and unlimited on every plan, including Free. No usage caps, no overage charges. We believe prediction market history should be accessible to everyone building in the space.

Question 7

How is orderbook tick history priced?

Accepted Answer

Tick-level orderbook history is billed separately via prepaid data credits, not your monthly plan. You get $50 in free credits when you add a payment method, and every download can be quoted for free before you're charged — pricing is per GiB of compressed Parquet ($40 for Polymarket, $80 for Kalshi and Opinion, $5 minimum), with a 10% bonus on top-ups over $500. Identical re-downloads within 24 hours are free. See docs.predexon.com/data-signals/ticks/data-credits for details.

Question 8
