Apify Ultimate Scraper

Gotchas and cost guardrails

Pricing models

To check an Actor's pricing:

apify actors info "ACTOR_ID" --user-agent apify-agent-skills/apify-ultimate-scraper --json

Read .currentPricingInfo.pricingModel and .currentPricingInfo.pricePerEvent.

Cost estimation protocol

Before running any PPE Actor:

1. Get the per-event price from Actor info (.currentPricingInfo.pricePerEvent)

2. Multiply by the requested result count

3. Present the estimate to the user with this disclaimer:

Estimated cost: ~$X for Y results. This is a rough estimate only - actual costs can vary significantly depending on the Actor, data complexity, retries, and platform changes. Always check your Apify billing dashboard for actual charges.

4. If estimate > $5: warn explicitly

5. If estimate > $20: require explicit user confirmation before proceeding

Important: Cost estimates in the workflow guides are approximate and may be inaccurate. Always present them as rough guidance with the disclaimer above, never as exact amounts.

Common pitfalls

Cookie-dependent Actors Some social media scrapers require cookies or login sessions. If an Actor returns auth errors or empty results unexpectedly, check its README:

apify actors info "ACTOR_ID" --user-agent apify-agent-skills/apify-ultimate-scraper --readme

Look for mentions of "cookies", "login", "session", or "proxy".

Input mechanics Actor input is one JSON object, not an array. --input accepts inline JSON object input only; wrap inline JSON in quotes to avoid shell parsing issues. For JSON files or complex inputs, use --input-file input.json. If the CLI reports parse, path, or object-shape input errors, inspect the schema again with apify actors info "ACTOR_ID" --user-agent apify-agent-skills/apify-ultimate-scraper --input --json.

apify actors call "ACTOR_ID" --input '{"maxItems":10}' --user-agent apify-agent-skills/apify-ultimate-scraper --json

Prefer this for larger inputs:

apify actors call "ACTOR_ID" --input-file input.json --user-agent apify-agent-skills/apify-ultimate-scraper --json

Rate limiting on large scrapes Platforms throttle or block large-volume scraping. Mitigations:

• Use proxy configuration when available: "proxyConfiguration": {"useApifyProxy": true}

• Set reasonable concurrency limits (check the Actor's maxConcurrency input)

• For 1,000+ results, suggest splitting into smaller batches

Empty results Common causes:

• Too-narrow search query or geo-restriction (try broader terms)

• Platform blocking without proxy (enable Apify Proxy)

• Actor requires cookies/login but none provided

• Wrong input field name (always verify with --input --json)

maxResults vs maxCrawledPages Different Actors use different limit field names. Common variants:

• maxResults, resultsLimit, maxItems - limit output items

• maxCrawledPages, maxRequestsPerCrawl - limit pages visited Always fetch the input schema to find the correct field for the specific Actor.

Deprecated Actors Check .isDeprecated in apify actors info "ACTOR_ID" --user-agent apify-agent-skills/apify-ultimate-scraper --json. If true:

1. Search for alternatives: apify actors search "SIMILAR_KEYWORDS" --user-agent apify-agent-skills/apify-ultimate-scraper --json

2. Prefer apify tier replacements over community alternatives

LinkedIn pricing LinkedIn Actors are all PPE and vary significantly:

• harvestapi/ Actors: generally cheaper ($0.001-0.01/result)

• apimaestro/ Actors: generally more expensive ($0.005-0.02/result)

• dev_fusion/ Actors: mid-range, useful for mass scraping with email enrichment Always compare pricing before selecting a LinkedIn Actor.

SEO tool pricing radeance/ SEO scrapers (SimilarWeb, Ahrefs, SEMrush, Moz) have the highest per-result costs ($0.005-0.0275/result). For large-scale SEO analysis, estimate costs carefully and suggest batching.

Error recovery

Why Apify Actors vs raw HTTP scraping

Many n8n and automation workflows use raw HTTP Request nodes or self-hosted Puppeteer for web scraping. These hit common walls that Apify Actors handle transparently:

Cloudflare and WAF bypass Raw HTTP requests fail on sites with Cloudflare Turnstile, DataDome, or other WAFs. Apify Actors use residential proxies and browser fingerprint rotation automatically. For the toughest sites, use apify/camoufox-scraper.

JavaScript-rendered pages (SPAs) React, Vue, and Angular sites return empty HTML to plain HTTP requests. Apify's apify/playwright-scraper and apify/camoufox-scraper fully render JavaScript before extracting data.

Anti-bot fingerprinting Even headless browsers get detected via TLS fingerprints (JA3 hashes). Apify's browser pool rotates fingerprints across requests automatically.

Session and cookie management Social media platforms (LinkedIn, Instagram) require persistent sessions. Social media Actors handle cookie management and session rotation internally.

Scaling without infrastructure Self-hosted Puppeteer at scale requires 4-8 GB RAM per browser instance. Apify Actors run on serverless infrastructure - no browser pool management, no RAM provisioning, no Docker orchestration.

Platform-specific rate limits

Instagram: Aggressive rate limiting. Keep maxResults under 200 per run for profile/post scrapers. Use delays between runs. Instagram API scrapers (apify/instagram-api-scraper) have higher limits than browser-based ones.

LinkedIn: All LinkedIn Actors are community-maintained and PPE. LinkedIn actively blocks scraping at scale. Keep batch sizes under 100 profiles. Space runs at least 5 minutes apart. Expect occasional empty results.

TikTok: Anti-bot measures increasing. clockworks/tiktok-scraper handles most cases. For blocked regions, enable Apify Proxy with residential IPs.

Google Maps: Generally stable. Set language: "en" explicitly for consistent results. Large-area searches may return different results depending on zoom level - use specific location queries over broad city names.

Amazon/E-commerce: Heavy anti-bot. The apify/e-commerce-scraping-tool handles this via built-in proxy rotation. Raw HTTP requests will fail.
