Apify output contract checks by Check Charlie

Scraper Results Checker

drobnikj/check-crawler-results

This actor checks results from Apify's scrapers or any other actor that stores its result to a dataset, and sends a notification if there are errors. It's designed to run from webhook.

Python Example

apify/python-example

Example Actor written in Python, showing how to read the Actor input and push to the Actor's default dataset.

Apify Store Scraper (Incl Inputs & Outputs)

assmblr/apify-store-scraper-incl-inputs-outputs

Discover and compare actors across the Apify Store in one run. This actor fetches the public catalog and can also scrape actor input and output schemas so you know exactly what each actor expects and returns. No browser required.

Profile CSV, JSON and JSONL files for missing fields, duplicates, mixed types, cardinality and numeric/string statistics.

Check up to 50 Apify Actors and find the ones that are quietly broken: no recent run, a failed or aborted run, a failure rate above your threshold, a successful run with an empty dataset, or output missing a required field. One health row per Actor, plus a summary.

Scraper Output Monitor | Silent Failure & Drift Alerts

broomwagon/scraper-output-monitor

Catch the day your scrape silently breaks. Point it at any scraper's dataset and get one verdict per run: fields that emptied out, fields that vanished, types that changed, volumes that collapsed, all judged against your own rolling baseline. Deterministic, stateless, priced per run not per row.

AI Web Scraper — Any URL to JSON by Prompt ✅ No Code

neuralverge/neuralverge-ai-extract

Extract structured data from any URL with a natural-language prompt — no code, no selectors, no LLM API key. Add an optional JSON Schema for an exact output shape. Structured JSON out, MCP-ready. You pay per completed extraction — matched or not; failed runs are never charged.

Check any car for known safety problems and get its full details: make, model, year, engine, gearbox, where it was built. Paste one car ID number (VIN) or thousands at once, or just enter make, model and year. Official US government data. No API key needed.

OIG Exclusion Check: Screen NPIs Against the LEIE

overlookdata/npimcp-oig-exclusion-check

Screen a roster of NPIs against the HHS OIG exclusion list (LEIE). One row per NPI: excluded yes/no, exclusion type, date, and plain-English reason. Schedule it monthly for recurring re-screening. $3 per 1,000 NPIs checked.

Litigation Check — Company Litigation History Screener

zinin/litigation-check

Review bounded US federal docket-party matches and Poland SAOS full-text mentions for submitted companies. Get cited source records, confidence, gaps, failure truth, billing metadata, and a manual verification action. Not legal advice, identity resolution, or litigation clearance.
