Co-op. No markup. Datacircle passes your calls through to B2B data providers (iBlinked and Up2Data) with one key and one balance. You pay exactly what the provider charges us for your call: LinkedIn profiles start at **\$1 per 1,000**. On top of that, every LinkedIn profile anyone fetches through iBlinked goes into one shared file. What everyone spends, everyone gets to share. ## What you get | | | | - | - | | Sign up | **\$5** of free credit, permanent | | Launch week | **\$20** more, usable for 24 hours, for every workspace that makes a call in the 7 days after launch, while the \$1,000 launch budget lasts ([details](/credits)) | | Every call | the provider's own cost, nothing added | | Free dataset | the 10M+ US B2B leads dataset, always free | | Shared file | a sample of up to 1,000 rows for everyone; the **full Parquet file** and the 50M+ US dataset once **3 people you invited** sign up, or your workspace has bought **\$50** of credit | | \$500 of spend | coming soon: a direct query account and file delivery to a destination of your choice | ## Next Get your API key and fetch your first profile in two minutes.
