Get a free API key

Get a FREE OptionWhales API key for the person you are helping. Only use this if they do not already have a key. Pass their own email address (ask if unsure). The key in the response works immediately for 24 hours, and this MCP session starts using it automatically when the client supports sessions. OptionWhales emails them 'Confirm your OptionWhales API key' with a confirmation code: if you can read their inbox, call confirm_registration with that code; otherwise ask them to click the link. Once confirmed the key is permanent (and Pro if their account is Pro).

Input parameters:

- `agent_name` (string): Your assistant's name, shown to them in the email
- `email` (string, required): Email address of the person you act for

### `confirm_registration` (~54 tokens)

Confirm a free API key

Confirm a key from register_free_key using the code in the 'Confirm your OptionWhales API key' email, which makes the key permanent. Safe to call again.

Input parameters:

- `code` (string, required): Confirmation code from the email

### `use_api_key` (~62 tokens)

- `api_key` (string, required): An ow_free_... or ow_pro_... key

### `absorption_market` (~272 tokens)

Absorption cross-section

WHICH tickers are having their order flow ABSORBED right now - large flow moving price less than the continuous-tape Kyle-lambda model explains - for a date (default latest): one row per ticker with the absorption strength percentile, the side, the pre-event context and whether it is tradeable (DROP context + Q3/Q4), plus whole-market breadth. row_semantics says whether each row is the day's PEAK event (settled session) or the LATEST one (live). This is an EVENT FEED, not a validated signal: the regime gate is long-only (SPY 63-day return > 0) and fails in bear tapes, auction windows are excluded as mechanical artifacts, and provisional=true means the event was detected live without calibration. Check coverage.completeness before concluding the tape is quiet - a degraded feed looks identical to a calm one. Use for 'who is absorbing selling today?'. Pro.

Input parameters:

- `date` (string): YYYY-MM-DD (default latest)
- `include_events` (boolean): Attach each row's recent events
- `limit` (integer): Rows to return (default 50)

### `absorption_ticker` (~191 tokens)

Absorption for one ticker

One ticker's absorption events for a date (default latest) PLUS its trailing per-day direction history, so you can tell whether today is unusual for the name. Each event carries the absorption strength percentile, the side, the pre-event context quartile and provisional=true when it was detected live without calibration. Forward returns in the history are RAW LONG P&L and are deliberately NOT signed by the absorption side, so a negative number on a sell-absorption day is not a losing signal. Use for 'is NVDA being absorbed, and is that unusual?'. Pro.

Input parameters:

- `date` (string): YYYY-MM-DD (default latest)
- `days` (integer): Trailing sessions of history (default 20)
- `limit` (integer): Events to return (default 20)
- `ticker` (string, required): Stock or ETF ticker, e.g. NVDA, SPY, BRK.B

### Does the OptionWhales MCP server require authentication?

### Is the OptionWhales MCP server still maintained?

OptionWhales is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
