Get the public trade feed of a prediction-market contract by its ticker

How to use it

Get the public tape of executed trades for a single prediction-market contract by its ticker. Returns each trade with its id, the number of contracts traded, the Yes and No execution prices, the taker side and outcome, a block-trade flag, and the trade timestamp. Optionally bound the feed to a time window with min_ts and max_ts (Unix seconds).

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• ticker string required — Market ticker of the tradeable Yes/No contract (examples: "KXBTCD-26JUN1604-T74799.99", "KXCS2MAP-26JUN161000TDKHOTU-2-TDK"; minLength: 1)
• count integer required — Max result count (examples: 20; min: 1)
• min_ts integer nullable — Earliest trade time as a Unix timestamp in seconds
• max_ts integer nullable — Latest trade time as a Unix timestamp in seconds

Response

• @type string (default: "KalshiTrade")
• trade_id string required
• ticker string nullable
• count number nullable
• yes_price number nullable
• no_price number nullable
• taker_side string nullable
• taker_book_side string nullable
• taker_outcome_side string nullable
• is_block_trade boolean nullable
• created_at string nullable

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — Market not found Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
