Getting started
Build
Seven things people build on the table, each in a handful of calls. Every step is a real request with its captured response.
| Build | What it is |
|---|---|
| Screener | One SQL WHERE clause screens every ticker server-side. |
| Backtester | As-of scans give point-in-time candidate sets with no look-ahead or survivorship bias. |
| Alert bot | Write the condition in SQL, get a push when it fires. |
| Trading algorithm | Define the entry and exit condition in one SQL q, backtest it as of any past moment, run it live as a webhook. |
| AI trading agent | The market as native MCP tool calls: raw and precomputed in one answer, so the model spends context on decisions. |
| Fintech app | One row per ticker with every signal, aligned series for the widgets, websocket push for freshness. |
| Custom signal | Define an indicator once as a SQL predicate and it works everywhere a built-in does. |
Before you build
Every guide assumes a key (Authentication, free, no card) and the one idea under all of them: every ticker is a row, every signal is a column, and a build is a WHERE clause on it, read live, as of any past moment, or as a webhook subscription. The Quickstart is the first call.
