One active key per account. It spends your credits like the app does, so keep it out of client-side code and public repos.

Send your key as a bearer token on every request. Keys start with <code>sk_live_</code>.

All paths are relative to <code>{baseUrl}</code>. Each account can start 6 analyses a minute and 60 an hour, and read a session 30 times a minute. Symbol lists allow 10 requests every 5 minutes from one IP address.

The body failed validation or doesn’t fit the mode, e.g. an unknown symbol or a monthly interval.

The session is still answering a previous message. Try again when it finishes.

The account is no longer on a paid plan (<code>SUBSCRIPTION_REQUIRED</code>).

The <code>strategyId</code> or <code>sessionId</code> isn’t one of yours.

The balance can’t cover the analysis. The message says how many credits it needs.

Something failed on our side. A failed analysis isn’t charged, and the body includes <code>sessionId</code> when one was saved.

More than 6 analyses a minute or 60 an hour on one account. Wait and retry.

The key is missing, malformed, expired or revoked.

Errors return a JSON body with an <code>error</code> message.

Use these IDs in <code>selectedIndicators</code>, up to 3 per request.

Send <code>sessionId</code> and <code>message</code> to continue a session, whether it started here or in the app. The symbol, chart and drawings come from the session.

The default. You choose the setup — <code>interval</code> or <code>timeframes</code>, indicators, a saved strategy and notes — and the agent analyses exactly that, as the Lite form in the app does.

Send a <code>message</code> as you would in the chat, and the agent chooses the timeframes and indicators itself. A conversational message costs 1 credit and returns no price levels.

Every analysis runs the same agent as the app and is saved as a session you can reopen there. <code>mode</code> chooses how it starts.

The three analyse endpoints take the same JSON body; which fields apply depends on the mode. <code>expertMode</code> and <code>analyzeRelatedNews</code> are still accepted and have no effect.

A successful analysis returns 200 with these fields. The price fields are <code>null</code> when the reply records no analysis, such as a conversational Pro message. Reading a session returns the same fields plus <code>status</code>.
