What you get

Every run writes a dataset with one row per record:

{
  "chain": "stellar-xlm",
  "tipLedger": 64636846,
  "ledgerHash": "87bdb927893cdb84\u2026",
  "closeIntervalSec": 5.0,
  "medianCloseSec": 5.0,
  "baseFeeLumens": 1e-05,
  "baseFeeStroops": 100,
  "txCount": 412,
  "opCount": 836,
  "successTxs": 355,
  "failedTxs": 57,
  "alerts": [],
  "previousState": null,
  "hostUsed": "https://horizon.stellar.org",
  "note": "first run: baseline snapshot \u2014 idle-gap/fee-spike/tx-spike alerts need KVS history",
  "fetchedAt": "2026-09-27T00:46:56Z"
}

Input

{
  "host": "https://horizon.stellar.org",
  "maxAlerts": 3,
  "runIntervalMs": 100000
}

Field	Type	Description
`host`	string	Host: the host parameter. Default: "https://horizon.stellar.org".
`maxAlerts`	integer	MaxAlerts: the maxalerts parameter. Default: 3.
`runIntervalMs`	integer	RunIntervalMs: the runintervalms parameter. Default: 100000.

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.
