Building on @alpacahq/alpaca-ts-alpha

This is a map, not the territory. It gives you the mental model, the idioms agents most often get wrong, and where to look — it deliberately omits the full API surface. Whenever you need specifics (exact method names, parameters, response fields), open the package README and grep the API reference: the README is ~2750 lines and its second half is an auto-generated, per-method reference. Do not guess method signatures from this file alone — confirm in the README or the source.

Where the source of truth lives

Paths are relative to the package root — the repo root when developing here, or node_modules/@alpacahq/alpaca-ts-alpha/ when installed (src/ ships in the published tarball).
