Dataset Cardinality & Anomaly Profiler

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

Dataset Drift Monitor

checksmithcats/dataset-drift-monitor

Scheduled scraper ran successfully, but did the output quietly change? Compare the current dataset shape with the latest baseline for count, field, missing-rate, and type-distribution drift.

CSV Join Quality Checker

junipr/csv-join-quality-checker

Check whether two CSV files are safe to join by analyzing key coverage, null keys, duplicates, type mismatches, whitespace/case drift, cardinality, unmatched rows, and likely row multiplication.

Watch public JSON GET endpoints for response-shape drift without an OpenAPI spec. The Actor learns the shape from the response, compares it against a stored baseline, and reports each field-level change with a breaking flag.

Compare 2-10 Apify datasets to detect changes, new/removed records, and duplicates. Features field-level diffs, smart merging, schema validation, data cleaning, and anomaly detection. Perfect for price monitoring, lead deduplication, and data quality tracking.

Job Posting Age Anomaly Detector

trovevault/job-posting-age-anomaly-detector

Find job postings that have stayed open unusually long in a city and function area. Returns posting age, anomaly flag, hard-to-fill signal, salary when available, and job URL.

Data Validator & Profiler — CSV JSON XML schema inference

perryay/data-validator-profiler

Validate and profile CSV, JSON, and XML datasets. Auto-detects schema (column types, null ratios, uniqueness), flags anomalies (mixed types, high nulls), and produces a detailed profile report. Supports batch mode for multiple datasets.

Profile any company website from its public surface: technology signals, emails, feeds, sitemap, security.txt, OpenGraph metadata and a structured completeness score. Built for lead qualification, research and agent workflows.

AI Search Visibility Monitor | Share of Voice | Anomaly Alerts

broomwagon/ai-search-visibility-monitor

Track your brand's share of voice across AI answer engines — ChatGPT, Perplexity, Gemini, Google AI Overviews. Deterministic deltas and statistical anomaly alerts against your rolling baseline, on a schedule. Stateless: you hold the memory, we store nothing.

Profile missing fields, nulls, empty strings, JSON types, distinct counts, and duplicate keys in an Apify dataset.
