What you get

Every run writes a dataset with one row per record:

{
  "chain": "polkadot",
  "blockHash": "0x729a28f74826e19cb5f2c84b2eef4ad2c1cbc088c4f2cda926686d7b9eb32aa3",
  "blockNumber": 33162170,
  "specVersion": 2005000,
  "runtimeName": "polkadot",
  "timestamp": "2026-09-26T01:12:46Z",
  "cadenceSec": null,
  "parentHash": "0x34b7d8d405e5916a3867e06584f47a8d59b5c14c2cd8820ad6e2159e9b333f4b",
  "alerts": [],
  "previousState": null,
  "hostUsed": "https://rpc.polkadot.io",
  "fallbackUsed": false,
  "note": "baseline (stateless CLI run) \u2014 stateful alerts require KVS history; timestamp is observation time (public Polkadot gateways do not serve the on-chain timestamp)",
  "fetchedAt": "2026-09-26T01:12:46Z"
}

Input

{
  "host": "primary",
  "cadenceWindowBlocks": 10
}

Field	Type	Description
`host`	string	Host: the host parameter. Default: "primary".
`cadenceWindowBlocks`	integer	CadenceWindowBlocks: the cadencewindowblocks parameter. Default: 10.

Use cases

Monitor on a schedule — run this Actor on a timer and get a fresh, normalized snapshot every time; diff the datasets to see what changed.
Feed a dashboard or model — clean, one-JSON-item-per-record output is ready to pipe into a spreadsheet, database, or LLM prompt without any post-processing.
Research & due diligence — pull a structured set of records for a topic, name, or window without scraping the public source by hand.

Limits & notes

No API key, no login: it only reads public endpoints/feeds. If the upstream source is degraded, the run still succeeds and returns an honest status item instead of failing.
Results reflect what the public source returned at run time (top-N windows, newest-first where applicable).
Pay-per-event via synthetic events: each default-dataset item is billed through apify-default-dataset-item ($0.001 per item), plus apify-actor-start.
Free to try on the free plan; PPE pricing applies to paid-plan users.
