Kestrel API

Kestrel, in your app.

Coming once v0.1.0 is published.

Build your own trading tools on our models: signals with plain-words explanations, the news reader's view, backtests with their net return after fees and worst dip, and the Eye data feed. Pinned to the Kestrel version you choose.

Kestrel API

What you can build with

Signals and explanations

Kestrel's calls with the reasons in plain words, as REST or a stream, pinned to a version.

The news view

Mood, urgency and the safety-brake alerts, live and with history.

Backtests

Fee-real backtests with their net return after fees and their worst dip; leverage is also compared with holding.

The Eye data feed

The data behind the Kestrel Eye map, for your own views.

Paper trading and bots

Paper trading, bots and portfolio endpoints, to build an app like ours.

Live orders, later

Placing real orders with your users' own exchange keys unlocks only when live trading switches on.

Versions and pricing

Calls on older published versions count once. Calls on the newest major version can count up to one and a half times; the weight is set when it is published and shown in the docs. Patch updates never change it.

What you need

An Atheron members account, used on the developer portal. Sign in with Atheron (our OAuth API) stays free.

Opening after v0.1.0

The API waitlist

The API waitlist opens on this site soon. Until then the newsletter says when it does, and you can write to us about the API.

Start on the developer portal

Keys are made on the developer portal

The docs, keys and the free Sign in with Atheron API are already there.

API keys are made on the developer portal once you sign in with your members account. This site cannot make one.

A tool, not advice. Kestrel makes no promise of results, and paper results are not real trading.
