Return an alpha's expression, settings, in-sample stats and submission checks.

Search the user's alphas. Use next_offset to page; BRAIN stops at offset 10,000.

Summarize an alpha's PnL by year, with optional recent daily cumulative values.

List the recordset names available for an alpha, for use with get_alpha_recordset.

Return one recordset as named rows. Prefer get_alpha_pnl for PnL.

Change an alpha's name, description, tags, color, category, favorite or hidden flag.

Run BRAIN's pre-submission checks. verdict is PASS, WARNING, FAIL or PENDING.

Return the alpha's highest correlation with the user's submitted alphas (limit 0.7).

Return the alpha's correlation with the production pool. Some account tiers get a 403.

Log in with the configured credentials, reusing a saved session when it is still valid.

Tools log in on their own, so this is only needed to start or restart a biometric check. When
state is biometric_required, have the user open biometric_url, then call
complete_authentication.

Finish a login after the user completed the biometric check at biometric_url.

Report whether a BRAIN session is active and when it expires. Never sends the password.

List datasets available for a market. Cached for a day.

Return one dataset with its full description, for example dataset_id 'pv1'.

Find the data fields usable in expressions.

BRAIN stops paging at 10,000 rows, so when truncated_by_api is true narrow with dataset_id or
search.

Return one data field with its full description, for example field_id 'close'.

Return the data category tree. Cached for a day.

List the FASTEXPR operators this account can use. Cached for a week.

Backtest one FASTEXPR expression and return its alpha with stats and checks.

A simulation usually takes 1 to 10 minutes. If it outlasts the timeout the result has status
PENDING and a simulation_id: call get_simulation_status to resume, never simulate again.
Identical expression and settings return the earlier result (from_ledger) without spending
quota. ERROR or FAIL results carry BRAIN's message, usually a syntax or field problem.

Backtest up to 30 expressions, sent to BRAIN in groups of at most 10.

All expressions must share one delay; different regions are sent as separate groups.
Multi-simulation needs a Consultant account. Expressions already in the ledger are returned
without spending quota. not_started lists anything that could not be sent; resubmit those later.

Check or resume a simulation. A finished one includes its alpha; a batch lists children.

List the regions, universes, delays and neutralizations this account may simulate.

by_context maps parent settings such as 'EQUITY:USA' to the values valid for them. Cached for
a week.

Return the user's BRAIN profile. Personal fields are withheld by default.

Return simulation or submission counts: yesterday, month to date, year to date, total.

Return platform messages, newest first, as plain text capped at 2,000 characters each.
