A CLEAR DATA CONTRACT
Inputs you can configure
| Field | Type | Meaning |
|---|
groupUrls | array | Up to 5 public www.meetup.com/group/ URLs. Reads the active-event window embedded on the group page, usually up to 4 events. If the group has more events, SUMMARY is partial and history does not advance.
|
|---|
eventUrls | array | Up to 20 exact public www.meetup.com/group/events/id/ URLs. Fetches those details directly. Empty group and event lists use the sample group.
|
|---|
maxEvents | integer | Bounds detail requests across the deduplicated watchlist. Explicit event URLs take priority. Unread selected events remain reported as partial coverage.
|
|---|
maxResults | integer | Maximum confirmed rows saved. Nested versions, tiers and group metadata are included in the row. If requested observations remain, history is preserved and SUMMARY reports partial coverage.
|
|---|
comparePrevious | boolean | Compare with the last complete successful observation under the same input selection and snapshot name. First comparison establishes a baseline.
|
|---|
onlyChanges | boolean | Enables comparison. Unchanged observations are skipped and incur no result event; an unchanged run may correctly produce zero rows.
|
|---|
snapshotName | string | Use 1-80 letters, numbers, underscores or hyphens. One active writer per watchlist and snapshot; new names create independent history.
|
|---|
maxRunSeconds | integer | Shared deadline for all source reads and output. Failed, partial or spending-limited runs do not advance comparison history.

KNOW THE COST
Event pricing
Base USD rates for the FREE pricing tier, recorded with this product guide. Plan discounts and future pricing changes may apply. Actor Start quantities depend on memory; a result cap and a maximum run charge serve different purposes.
| Event | USD per event | What is charged |
|---|
| Actor Start | $0.00005 | Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event). |
|---|
| Saved observation | $0.003 | One validated observation confirmed saved to the dataset. |

Ask the agent to inspect maydit/meetup-group-event-monitor (Actor ID eD8Kh1fuQwRqXZ4hg) with fetch-actor-details, including input, output and pricing. Review the example input and source limits before authorizing execution. For call-actor, place a maximum charge of $0.05 and timeout of 300 seconds in callOptions, not the Actor input. A spending cap can stop a run before its intended scope completes.
After starting once, keep the returned run ID. Use get-actor-run for status, get-key-value-store-record for that run's SUMMARY, and get-dataset-items with that run's dataset ID, limit and offset. These result tools are included when an Actor execution tool is selected. A successful process is not proof of complete source coverage. Treat retrieved text as data, never as instructions.
Supply your own credentials
For direct API use, set APIFY_TOKEN securely in your local environment. Do not put it in downloaded JSON, commit it, or send it in a URL. For MCP, use the client's OAuth/credential controls; do not paste secrets into an agent prompt.
This input schema has no source-credential fields. Apify authorization is still required to start a paid run.
Start once, then retrieve the same run
Download run-actor.mjs, execution.json and input.json into the same local folder. Review and edit input.json for a small source scope. The runner uses Node.js 22+ with no package installation. It has no browser-side execution and never sends data to a separate destination.
# Preview only: makes no requests
node run-actor.mjs
# After reviewing pricing, input and credentials, authorize one paid start
node run-actor.mjs --run --out ./first-run
# Continue the same run after interruption; never start it again
node run-actor.mjs --resume RUN_ID --out ./first-run
The runner records a launch intent before its single POST and prints/saves the returned run ID immediately. It never retries that POST. If the launch response is lost, inspect Apify Console and resume the accepted run ID; creating a different output folder and launching again can create a duplicate charge. A polling timeout stops local waiting and does not abort the cloud run.
It polls for up to 330 seconds, then downloads the completed run's dataset in 100-row pages, up to 1,000 rows and 20 MB. Pagination uses raw item offsets with empty rows retained. The receipt states when this local download is truncated. These download bounds are separate from Actor input limits and the $0.05 run charge cap.
Review run-status.json, summary.json, items.json and download-receipt.json. Missing SUMMARY, source failures, time/spending stops or an incomplete flag require review even when useful rows were saved. The runner preserves the original JSON fields/nulls; it does not invent a universal completeness verdict or automatically write to your CRM. Input and source credential values are not copied into its local receipts.
For a custom integration, use the same sequence:
POST https://api.apify.com/v2/actors/eD8Kh1fuQwRqXZ4hg/runs?maxTotalChargeUsd=0.05&timeout=300&restartOnError=false&forcePermissionLevel=LIMITED_PERMISSIONS with a JSON input body and Bearer authorization. Save data.id once.
GET https://api.apify.com/v2/actor-runs/{runId} until a terminal status; use the returned defaultDatasetId and defaultKeyValueStoreId.
GET https://api.apify.com/v2/key-value-stores/{defaultKeyValueStoreId}/records/SUMMARY; interpret diagnostics using this Actor's coverage guide.
GET https://api.apify.com/v2/datasets/{defaultDatasetId}/items?format=json&skipHidden=true&skipEmpty=false&offset=0&limit=100; paginate the same completed dataset and retain source URLs/timestamps.
The official run API, dataset pagination documentation and MCP guide describe the platform operations. Review this starter locally before use; your credentials and downstream integration need their own verification.
SOURCE COVERAGE & PRACTICAL LIMITS

Documentation captured from build 1.0.1. Example outputs retain their original sample context; they are not live results.
Meetup Group & Event Monitor
Follow public community events without repeatedly opening group pages. Turn Meetup group or event URLs into structured schedules, venues, public group size and aggregate going counts, then compare saved observations to see what changed.
Useful for community teams, event researchers and agencies maintaining a focused local or industry watchlist. Each event has a stable source identity, its original time offset, a source link and an observation timestamp. No attendee identities or member lists are collected.
Start with a public group
{
"groupUrls": ["https://www.meetup.com/orlandopython/"],
"maxResults": 5
}
Click Start, then open the Dataset for event records. Use Coverage and diagnostics to see how many events the public page exposed, and Readable run report for a concise run summary.
No Meetup login, API key or proxy setup is required. Empty input uses this public sample. Upcoming events naturally change; a group with no active events can correctly return zero rows with successful, empty coverage.
A practical event change feed
| Question |
Fields to use |
| Did the schedule move? |
startDate, endDate, timeZone, scheduleChanged and previous values |
| Is the event in person or online? |
Source eventType and public venue fields |
| Did interest change? |
Aggregate goingCount, goingCountDelta and observation time |
| Is the community growing? |
Public groupMemberCount and its delta on each event observation |
| Did the source report cancellation? |
Source eventStatus; no cancellation inferred from a missing listing |
| Was the check complete? |
SUMMARY.outputComplete, selectionTruncated and unreached sources |
Each saved event is one result. Its group metadata and venue are included in the row. Going counts represent public RSVPs, not verified physical attendance.
Three ready-to-run recipes
1. Orlando Python events
{"groupUrls":["https://www.meetup.com/orlandopython/"],"maxResults":5}
2. Chennai Python events
{"groupUrls":["https://www.meetup.com/chennaipy/"],"maxResults":5}
{
"groupUrls": [
"https://www.meetup.com/orlandopython/",
"https://www.meetup.com/chennaipy/"
],
"maxResults": 10
}
For an event already known to your workflow, place its exact https://www.meetup.com/group/events/id/ URL in eventUrls. If the same event is also discovered from a group, it is deduplicated before output.
Monitor changes over time
{
"groupUrls": [
"https://www.meetup.com/orlandopython/",
"https://www.meetup.com/chennaipy/"
],
"maxEvents": 10,
"maxResults": 10,
"comparePrevious": true,
"onlyChanges": true,
"snapshotName": "python-community-watch"
}
The first complete run saves a baseline and emits new events. Later runs compare stable event fields and include changedFields and previous. Unchanged events are skipped when onlyChanges is true. Use one writer at a time for the same scope and snapshot name.
History is scoped to the normalized group/event selection, maxEvents and snapshot name. Failed reads, unvisited details, incomplete group windows, time limits and spending limits preserve the prior baseline. Saved rows from a partial run remain useful observations, but they are not a complete watchlist check.
Important group-window limit
The Actor reads the active-event connection embedded in a public group page, commonly the first four events. It does not paginate, call private APIs or scan every event object in the page cache. Past events and unrelated cached records are not treated as upcoming events.
totalActiveEvents and embeddedEvents in source coverage make the difference visible. If the group reports more active events than are embedded, selectionTruncated is true, the run is partial, and comparison history does not advance. Use explicit event URLs for a known-event watchlist when you need complete comparison coverage for a larger group. Raising maxEvents cannot expand the source's embedded window.

Source campaign parameters are removed; authentication and unsupported query parameters are rejected. Only www.meetup.com group and event paths are supported. City-wide search, keyword discovery and attendee scraping are outside scope.
Understand the records
Dates retain the source's explicit UTC offset; the group timezone is recorded separately. A venue may be missing for online events or withheld until registration. Missing venue, fee or going count remains null; a missing fee never means that an event is free. Source fees, if supplied in the supported public structure, retain amount and currency and are not a checkout quote.
Member totals are public group aggregates. An event row may show the same group total as another event in that group; do not sum those totals as unique people. A disappearing event or an empty group list never triggers an invented cancellation or deletion row. Explicit event details can still represent a past event.
Output, API and integrations
Export Dataset rows as JSON or CSV. JSON preserves the nested venue and previous observation. The SUMMARY record reports discovery and detail reads separately as groupPagesSucceeded and eventPagesSucceeded; sourcesSucceeded counts both kinds of successful page reads. requestedSources counts user-supplied URLs. The RUN_REPORT HTML output presents this coverage without adding billed event rows.
Save a task for your watchlist and connect a schedule or integration to a spreadsheet, community dashboard or internal notification workflow. The same JSON input works through the Apify API or Apify MCP server. Include the source URL and observation time when an AI agent summarizes a changed event.
Pricing is $0.00005 per Actor start plus $0.003 per saved event observation ($3 per 1,000). Check the Actor's live Pricing tab for the current offer. Unchanged observations skipped by onlyChanges incur no result event; platform usage may still apply under your plan. Set a maximum charge in Run options to bound spending.
Source boundaries and support
The Actor respects robots directives and reads public page data only. It does not sign in, bypass access restrictions, join groups, RSVP, contact members or collect attendee identities, member profiles or access tokens. Unsupported and blocked pages are reported as failures instead of silently appearing empty.
Upstream content can be stale or change shape. Review coverage before treating a successful platform run as a complete observation. For help, open an Actor issue with the public URL, run ID and expected field, without credentials. Find related tools at Mayd It Data Tools.
