Use the exact Tool orderbooks-blockrun with the user’s existing Toolmu connection; if needed, follow https://toolmu.com/SKILL.md. The user may provide a public Opinion market link or the full question on the market page. First use the Opinion markets Tool named opinion-markets-blockrun to find a unique match and confirm the returned market title. Use the matching market internally; never ask the user to search for a number or code on the market page. If multiple markets match, show their full questions and ask the user to choose. If none match, request a public market link or complete question.

Ask for any missing start date, end date, time, or time zone. Keep the exact range the user requested, convert it to the time format required by the history Tool, and do not guess a time zone or change dates. Before using a Tool, confirm that it is available and that its cost fits the user’s approved balance and budget.

Explain only the records actually returned. They are historical buying and selling prices for the “Yes” choice, not live prices or completed trades. No records means none were returned for the chosen market and dates; it does not establish what is happening in the market now. This Tool provides only the “Yes” choice; do not invent “No” data.

Task:
Show “Yes” price history for [Opinion market link or question] over [start and end dates, times, and time zone].

Opinion Orderbook History and Past Prices | BlockRun

Check Opinion orderbook history using a public market page link or its full question and a time range. Your Agent can look up the market and explain available past “Yes” prices in plain language.

You receive

Get a page of historical YES-side orderbook observations for the Opinion market and interval you provide, with paging information. When records are available, their times, price levels, best bid and ask, and reported depth let your Agent present or compare the returned observations.

Start with your task

Show “Yes” price history for [Opinion market link or question] over [start and end dates, times, and time zone].

What to know

This is historical YES-side data, not live order placement or a continuous feed. Availability varies by market and interval; an empty page does not prove that the current orderbook is empty.

Inputs & outputs

Inspect the current inputs, availability, and maximum charge before starting.

Input schema

Input schema
Field / Path	Type	Requirement	Meaning
Market and time range`queryParams`	`object`	Optional	Place integer market_id, start_time and end_time directly in this object. Both times are Unix milliseconds. Optional limit accepts an integer from 1 to 200, defaulting to 100; pagination_key carries a returned continuation cursor.
Nested query object`queryParams.query`	`object`	Optional	An optional nested object in the input contract. For this endpoint, put the supported query controls directly in queryParams rather than inside this nested object.

Result schema

No fixed output contract is available. Field types reflect saved result evidence; individual responses can differ.

Result schema
Field / Path	Type	Meaning
Orderbook snapshots`result.snapshots`	`array`	Historical YES-side orderbook observations in this response. An empty array means this request returned no snapshots; it does not establish that the current orderbook is empty or that the market has no history.
Page information`result.pagination`	`object`	Paging context for this response: its count, limit, continuation flag and cursor. It does not establish a total across every page.
Snapshots in this page`result.pagination.count`	`number`	The number of snapshots in the current response, rather than the number of orders, trades or snapshots in the entire market history.
Page limit`result.pagination.limit`	`number`	The page limit reported by the source. It is a maximum for the page, not a promise that this many snapshots were returned.
More records available`result.pagination.has_more`	`boolean`	Whether the source reports more records beyond this page. This flag is separate from whether the request succeeded.
Continuation cursor`result.pagination.pagination_key`	`null`	An opaque key for a next page when supplied. Preserve the original string; null means no usable key was supplied.

Additional notes

Check Opinion orderbook history

Share [the public Opinion market page link] or [the full question on the market page], then provide [a start date, time, and time zone] and [an end date, time, and time zone]. Your Agent can look up the matching market; if it is unclear, it will ask you to choose. Available history begins on March 10, 2026, but not every market or time range is guaranteed to have records.

What the price history shows

Available records show past buying and selling prices for the “Yes” choice at the listed times. These are historical prices, not live prices or completed trades. If no records are returned, none were found for the market and time you chose; that does not say what is happening in the market now.

See the Opinion orderbook reference for the official source. To connect your Agent, follow the Toolmu connection guide.
