Ethereum Multi-Address Watch

Keyless multi-address watch on Ethereum (public Blockscout v2 instance, no API key): per-address ETH balance, 24h tx in/out + volume, token-transfer volume, contract/verified flags. Watchlist input. Stateful KVS deltas; alerts on large inflow/outflow.

What you get

Every run writes a dataset with one row per record:

Field	Type	Description
addresses	string	Addresses: the addresses parameter. Default: "0xd8dA6BF26964aF9D7eEd990f4655f6938399064d,0x7a250d5630F4cC7b4001d934bEa738EFDdA0eADc,0xC02aa33bfa2a5fc72e86d6b1f7bdde419b6e2afc,0x6B175474E89094C44Da98b954E9AC8fc578a2E6C".
limit	integer	Limit: the limit parameter. Default: 50.

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.
