Example outputs

@blitz-api get the full company profile for Stripe using their LinkedIn page, then break down their employee distribution by department
Stripe profile retrieved: 8,000+ employees, headquartered in San Francisco, operates in financial services and payments technology. Employee distribution by department: Engineering 42%, Sales 18%, Product 12%, Operations 10%, Marketing 8%, Customer Success 6%, Other 4%. Both the company profile enrichment and department breakdown each consumed 1 record credit (2 credits total). Founded 2010, publicly traded, primary domain stripe.com.
Each distinct API call (Enrich Company, Get Employee Distribution) consumes separate record credits—plan your workflow to minimize redundant lookups. The Enrich Company tool requires the exact LinkedIn company URL, which you can obtain first using Resolve Domain to LinkedIn Company if you only have a website. Department percentages are approximations based on public LinkedIn data.
Use-case deep-dives
When Blitz API beats manual LinkedIn scraping for cold outreach
A 3-person sales team building a list of 200 target contacts at Series A fintech companies can use Blitz API to turn LinkedIn company URLs into verified work emails in under an hour. The Find Work Email and Enrich Company tools consume record credits per match, so you pay only for verified hits—no wasted spend on bounced addresses. The Get API Key Details tool shows your remaining balance before you burn through a large list. This works when your ICP is narrow enough that you can hand-pick the 40-60 target companies first; if you need to score thousands of accounts by headcount growth or hiring velocity, Blitz's metered pagination gets expensive fast. For targeted outbound at seed stage, the credit model and verified-email guarantee make this the right call.
Using Blitz to monitor competitor headcount and hiring
A product team at a 12-person B2B SaaS company tracks three direct competitors by running Get Company Employee Distribution and Find Companies Hiring weekly. The employee-distribution tool shows department breakdowns (engineering vs. sales headcount ratios) and the hiring tool surfaces which roles each competitor is filling. Both consume record credits, so the team budgets 50 credits per week across all three competitors. This scenario works when you have a short watch-list and care about directional trends, not real-time alerts. If you need daily snapshots or want to track 20+ competitors, the per-call credit cost adds up and you should look at a dedicated market-intelligence platform instead. For quarterly board decks and roadmap prioritization, Blitz gives you the data without a five-figure annual contract.
When Blitz API accelerates channel-partner discovery
A two-person biz-dev team at an API-first startup uses Resolve Domain to LinkedIn Company and List Company Employees to qualify 80 potential integration partners in a week. They start with a CSV of company domains from a trade-show list, resolve each to its LinkedIn page, then pull the first page of employees filtered by 'partnerships' or 'business development' titles. The List Company Employees tool returns one metered page per call, so they get 10-25 contacts per company without paying for full employee exports. This works when you need just enough context to write a warm intro, not a complete org chart. If you're doing deep account mapping across 500+ partners, the pagination model forces too many API calls and you'll want a CRM enrichment tool with bulk-append pricing instead. For fast partner research at early stage, Blitz delivers the signal without the enterprise sales cycle.
Frequently asked
What does the Blitz API MCP do in Switchy?
It lets your AI agents enrich company profiles, find work emails, and search employees directly from LinkedIn data without leaving the chat. Agents can resolve domains to LinkedIn pages, pull org charts by department or location, and track hiring activity across companies. Every lookup that returns a match consumes record credits from your Blitz API balance.
Do I need a paid Blitz API key to connect this MCP?
Yes. You authenticate with an API key that carries your record balance and rate limits. The Get API Key Details tool shows your remaining credits and which endpoints your plan allows. Free-tier keys exist but typically have tight rate limits and small record quotas, so most teams need a paid plan for production use.
Can the Blitz API MCP send emails or update LinkedIn profiles?
No. It only reads and enriches data—company profiles, employee lists, verified work emails. It cannot post to LinkedIn, send messages, or write back to any CRM. If you need to push enriched contacts into HubSpot or Salesforce, pair this MCP with a CRM integration that has write tools.
How is this different from scraping LinkedIn myself or using the official API?
LinkedIn's official API does not expose employee lists, org charts, or personal work emails. Blitz API maintains its own enrichment database and handles the compliance and rate-limit complexity. You trade per-record cost for speed and breadth—agents get structured JSON instantly instead of parsing HTML or waiting on manual exports.
Who on my team should connect the Blitz API key?
Whoever owns your sales or recruiting data budget. Each successful lookup burns record credits, so the person who monitors usage and tops up the balance should authenticate. Once connected, any Switchy workspace member can invoke the tools, but all consumption rolls up to the single shared key.
