Blockscout Contract Watch

Keyless EVM contract & protocol watch via public Blockscout (no API key): per-address new transactions, transfers, and gas spent since the last run (stateful KVS diff). Monitor any list of contract addresses on public Blockscout chains. One compact pulse item per run.

What you get

Every run writes a dataset with one row per record:

Input

{
  "addresses": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48,0x7a250d5630B4cF539739dF2C56aCcb5c3dCc99F6",

Field	Type	Description
addresses	string	Addresses: the addresses parameter. Default: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48,0x7a250d5630B4cF539739dF2C56aCcb5c3dCc99F6".
limit	integer	Limit: the limit parameter. Default: 20.

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.
