Three tiers, no surprises.
The free tier is genuinely free forever — no signup, no email, no card. It covers 20 exchanges, ~6,800 perpetual symbols, the divergence scanner, the autonomous signals feed, the daily research blog, and 10 trader calculators. The paid tiers add historical data, higher rate limits, and Telegram alerts. Pricing is intentionally below the dominant alternative because we don't have an enterprise sales team to feed.

FAQ
Why is this so cheap compared to Coinglass / CoinAPI?
Because we don't have an enterprise sales team, a marketing budget, or a fundraising round to feed. The product is built and operated by one person on a $5/month VPS. Our break-even on the Trader tier is around 30 paying users.
Can I cancel anytime?
Yes. No annual lock-in. Cancel from your account dashboard, no questions asked.
Is my historical data backfilled or only forward-collected?
Forward-collected from the launch date. The 30-day history on Trader will be fully available 30 days after you sign up if you sign up today; for the full 30 days from day one, the rolling collection has been live since 2026-04-07.
Do I need exchange API keys?
No. We pull from public exchange endpoints only. Funding Finder never has access to your funds, your positions, or anything in your exchange accounts. It's a pure data service.
What if a free user makes more requests than the rate limit?
You get a 429 with a clear error message. No silent throttling, no surprise bill, no account ban. Wait a minute and try again, or upgrade.
Is there an open source version?
Yes. The collector + SQLite schema is MIT-licensed and downloadable directly from this server: pip install http://178.104.60.252:8083/downloads/funding-collector-0.4.3.tar.gz. 20 fetchers, 14 unit tests, no auth, no telemetry. You can self-host the data layer for free if you prefer that to a hosted service. The web dashboard, API, alerts, history endpoints, and the autonomous signals/research/tools layers stay as a hosted product.
Where do I sign up while the paid tiers are not yet billed?
Drop your email on the /now page. When the paid tier launches, the people on the waitlist get a one-time email and a free upgrade. No spam, no follow-up sequence — single email.
What if I just want to read?
That's the free tier. Use /now as a daily glance, /signals as a feed reader subscription, /research for the daily analysis, /heatmap when you want the full picture, and the /tools calculators when you need a number. None of it requires an account.
