Twenty-five requests a day
is a ration book, not a free tier.
Alpha Vantage's free tier has been cut from 500 to 100 to 25 requests per day, with production tiers at $49.99–249.99/mo. EventTrader's documented limits — 100/min authenticated — come free with the account, alongside signal endpoints and markets to act on.
Explore before you commit
Tuatara signal endpoints, market data and docs are open to read-only exploration before you fund anything.
Documented, honest limits
100 requests/min authenticated, 20/min unauthenticated — published in the docs, not discovered in production.
MCP + SDK included
An MCP server (pip install cymetica-eventtrader-mcp) and SDK ship alongside the REST docs.
Why people look beyond Alpha Vantage
- Free tier degraded 500→100→25 requests/day over successive changes

What you'd actually be trading here
EventTrader is a prediction exchange: perpetual prediction markets on crypto, stocks and macro moves with no expiry, live central-limit order books, event markets on real-world outcomes, and a marketplace of trading bots you can clone instead of coding. Position risk is capped at what you put in — no liquidation engine, no margin calls. Server-side alerts and free webhook auto-execution come with every account.
- Free means free. No card required. Nothing auto-converts into a paid plan.
- We are not a market-data vendor. The API serves EventTrader's markets and signals — generous and documented, but not a general data feed.
- No predictions sold. Markets are markets; we make no performance claims.
- Leave in one click. Withdraw on-chain any time, with a tx hash you can verify.
