Coresignal Bundle

Firmographic and workforce intelligence—not a phone book. Coresignal skills connect Claude to company, employee, and jobs APIs (Elasticsearch-style search, headcount history, talent flow, market monitoring) so you build maps, narratives, and ranked targets from live business data. When you need who works where, how teams changed, and which markets are heating up, this is the bundle.

Why this bundle exists

Recruiting and strategy teams already buy Coresignal for signals competitors cannot copy from a simple contact DB. The gap is turning those queries into repeatable briefs: NL → DSL → Excel → Claude analysis. These skills close that loop and make exports land in formats BD and TA can share.

How you benefit

• Search without becoming a search engineer — Natural language becomes Elasticsearch-style queries with validation and structured outputs.
• Talent maps that win exec buy-in — map-company-talent and track-talent-flow combine API facts with Claude narratives for sourcing and competitive strategy.
• Market monitoring — monitor-job-market and search-jobs track segments over time instead of one-off screenshots.
• Honest scope — This bundle does not fabricate corporate emails or direct phones; pair with ContactOut, Apollo, or Hunter for contact completion after you have chosen targets.

Example prompts

When Claude has access to Coresignal through this bundle’s API integration (with your keys and project configured), you can ask in plain language—for example:

• Turn this NL question into an employee search for ‘ML engineer’ in fintech scale-ups and export profiles to Excel.
• Map headcount trends for these ten competitors over the last four quarters and summarise what it means for sourcing.
• Search job postings for ‘platform engineer’ in the UK and give me a market read in a second tab.
• Score this exported spreadsheet of companies against our expansion brief—no extra API calls, Claude only.

Full power (easy to miss)

• score-candidates is Claude-only: score any spreadsheet export repeatedly while you tune rubrics—no extra Coresignal API spend.
• export-intelligence includes ATS-style templates and slide-ready summaries so intelligence escapes the data team’s laptop.
• Coresignal is enterprise-priced; treat keys like production secrets and use skills’ patterns to avoid accidental wide queries.

What you get

Digital download: a ZIP you unzip into your project.

Coresignal API access is enterprise-priced and requires a commercial agreement. Obtain API keys from the Coresignal dashboard or your account manager. There is no meaningful free tier for production API use.

API notes

Public documentation specifies header apikey with your API key (not Bearer JWT). Default client uses https://api.coresignal.com/cdapi as in official examples; override with CORESIGNAL_API_BASE if needed. Optional CORESIGNAL_USE_BEARER=1 uses Bearer authentication instead.

Credit multipliers follow published rules: multi-source company and employee successful search/collect requests typically cost 2 credits; clean/base and jobs tiers typically cost 1 credit per successful request (confirm against your contract).
