jpmarketdata--paypay-flea-price-checkerThis tool calls the Actor "jpmarketdata/paypay-flea-price-checker" and retrieves its output results. Use this tool instead of the "call-actor" if user requests this specific Actor. Actor description: Get instant price statistics (median, average, range) plus like-count demand signals from PayPay Flea Market, Japan's #2 flea market app. One call answers: what is this item going for?
get-actor-runGet detailed information about a specific Actor run. Returns run result: status, storages (datasets/keyValueStores alias map), stats, summary, nextStep. - summary describes the past (e.g. "SUCCEEDED in 22s. 47 items; 3 fields available."). - nextStep prescribes one primary follow-up action with identifiers interpolated (e.g. "Use get-dataset-items with datasetId=..."). - waitSecs (0–45, default 30) waits up to that many seconds for terminal status before returning. USAGE: - Use to check the status of a run started with call-actor. - Pass waitSecs > 0 to block until terminal (or until the cap elapses). - If `call-actor-widget` or `get-actor-run-widget` rendered a widget for this run, do NOT poll here — the widget self-polls. USAGE EXAMPLES: - user_input: Show details of run y2h7sK3Wc - user_input: Wait for run y2h7sK3Wc to finish
get-dataset-itemsGet items (rows) from a dataset — the output/results produced by an Actor run. Not metadata or schema — use get-dataset for counts and the field list, get-dataset-schema for a JSON schema from a sample. When the user provides a datasetId and asks to retrieve results, output, data, or rows, call this tool directly — do not call get-dataset first. Default limit is 20. Use clean=true to skip empty items and hidden fields. USAGE: - Use when you need to read data from a dataset (all items or only selected fields). USAGE EXAMPLES: - user_input: Retrieve results from dataset abc123 - user_input: Get only metadata.url and title from dataset username~my-dataset
get-key-value-store-recordGet the value stored under a specific key in a key-value store — a single record, not a listing of all keys. Use get-key-value-store-keys first if you don't know the key name. The response preserves the original Content-Encoding; most clients handle decompression automatically. USAGE: - Use when you need to retrieve a specific record (JSON, text, or binary) from a store. USAGE EXAMPLES: - user_input: Get record INPUT from store abc123 - user_input: Get record data.json from store username~my-store
abort-actor-runAbort an Actor run that is currently starting or running. For runs with status FINISHED, FAILED, ABORTING, or TIMED-OUT, this call has no effect. The results will include the updated run details after the abort request. USAGE: - Use when you need to stop a run that is taking too long or misconfigured. USAGE EXAMPLES: - user_input: Abort run y2h7sK3Wc - user_input: Gracefully abort run y2h7sK3Wc
