## FAQ

### How does the Unified Credit System work?

$1 equals 10,000 Credits (1 Credit = $0.0001). Full person profile enrichment (/v1/profile) and company firmographic enrichment (/v1/company) cost 10 Credits ($0.001 base, or $0.0004 on the Business plan). Decision-maker people search (/v1/people/search), B2B post search (/v1/posts/search), and hiring signals (/v1/jobs/search) cost 2 Credits per returned item ($0.20 / 1,000 items, with a minimum floor of 10 Credits on non-empty responses and 0 Credits when empty).

### Can I migrate from Proxycurl or Clearbit without rewriting my application?

Yes. LinkedInDataAPI supports drop-in compatibility aliases including GET /api/v2/linkedin (accepting ?url=https://www.linkedin.com/in/satyanadella) and GET /v1/company?domain=stripe.com. You can switch base URLs to https://api.linkedindataapi.com in under 5 minutes and reduce enrichment costs by up to 95%.

### Do I need to supply LinkedIn session cookies (`li_at`), residential proxies, or browser accounts?

Never. LinkedInDataAPI is a 100% no-cookie enterprise B2B intelligence gateway. We handle all upstream multi-provider routing, caching, and schema normalization so your team never risks employee account bans or proxy maintenance.

### Am I charged when a profile is not found (404), empty, or rate-limited?

Never. Only HTTP 200 responses with code === 0 and non-empty data deduct credits. Profile/company 404 Not Found responses, empty search results, invalid parameters (HTTP 400), rate-limited requests (HTTP 429), and upstream errors (HTTP 5xx) cost 0 Credits.

### Should I choose a Monthly Plan or Pay-As-You-Go (One-Time Top-Up)?

Both credit your account with the exact same bonus credit packages (Starter 250,000 Credits, Pro 1,200,000 Credits, Business 5,000,000 Credits). Pay-As-You-Go top-ups have no recurring billing and your purchased credit balance never expires. Monthly subscriptions save up to 24% more for continuous CRM and AI SDR enrichment workloads.

### What are the concurrency, pagination, and RPM rate limits?

Free Trial accounts include 2,000 Credits (200 full profile/company enrichments), 30 RPM, and the first 2 pages per search query. Paid accounts unlock deep cursor pagination and scale from 120 RPM (Starter) and 300 RPM (Pro) up to 600 RPM (Business) backed by automatic 5-provider upstream failover.

### What payment methods are accepted?

You can pay instantly by credit or debit card (Visa, Mastercard, American Express, Apple Pay, and Google Pay via Stripe with automatic official PDF invoices and corporate VAT/Tax ID support) or top up with 0%-fee cryptocurrency (USDT or USDC on Tron, BNB Smart Chain, Ethereum, Solana, Arbitrum, and Polygon, plus BTC, SOL, and BNB).

### Can I use LinkedInDataAPI inside Claude Desktop, Cursor, Clay, or AI SDR agents?

Yes. Configure our Model Context Protocol (MCP) server in Claude Desktop, Cursor, or Windsurf to give AI agents real-time person lookup, company firmographics, decision-maker search, and hiring signal tools. You can also call our REST endpoints directly from Clay, Make, n8n, or LangChain.

### What data privacy and compliance standards does LinkedInDataAPI follow?

LinkedInDataAPI exclusively indexes and structures publicly available professional profile, company firmographic, and job posting metadata. We never harvest private personal emails, residential phone numbers, or authenticated graph data, and we automatically strip any masked or sensitive PII at the gateway layer.

### Is LinkedInDataAPI affiliated with LinkedIn, Microsoft, Clearbit, or Apollo?

No. LinkedInDataAPI (linkedindataapi.com) is an independent developer infrastructure provider for publicly available B2B intelligence and is not affiliated with, endorsed by, or sponsored by LinkedIn Corporation, Microsoft Corporation, Clearbit/HubSpot, or Apollo.io.

### How much does it cost to enrich 100,000 B2B profiles or companies?

At 10 Credits per profile or 10 Credits per company ($1.00 / 1,000 base), 100,000 full enrichments cost $100 base — or just $57.50 on the Pro plan and $39.80 on the Business plan. For decision-maker search at 2 Credits per person (up to 25 people per call), 100,000 leads cost only $8.00 on the Business plan — up to 95% lower than Proxycurl, Clearbit, or People Data Labs.

### What is your refund policy?

Payments made within the last 30 days can be refunded up to the unused purchased balance on your account. Promotional signup credits have no cash value.
