How to get an API key

UpLead uses API key. The steps below follow UpLead's own docs.

Create a UpLead account. API access starts on the Professional plan.
API key in UpLead account settings; docs and /data-api/ also link a 'Get a Free API key' Google form (forms.gle/cMKiUHAUsiAnf1Gb8)
Send it with every request: header Authorization: <api_key> (no Bearer prefix).
Make a first call: Paginated saved lists. Keep the key in an environment variable, never in the command.
```
curl -X GET "https://api.uplead.com/v2/lists" \
  -H "Authorization: $UPLEAD_API_KEY"
```

Strengths and limits

Where it fits

Cheap, simple per-record enrichment by domain, email, or name+domain
Prospecting contacts at a known domain by function, sub-function, management level, title and location
Company name to domain resolution
Free company logos by domain (logo.uplead.com, attribution required)
Not paying for bad emails: credits only deducted when email_status is Valid or Accept All

Where it falls short

API on self-serve plans: pricing page lists Enrichment API, Prospector Pro API and Full API Access only on Professional (annual, sales-led)
Intent, signals, job-change tracking or webhooks via API
EU-heavy outreach where phone verification depth and DNC handling matter
AI-agent/MCP workflows (no MCP server)
Bulk async jobs (no bulk endpoint; max 100 per page)

Worth knowing

Plan gating conflict: pricing page shows Enrichment API, Prospector Pro API and Full API Access only on Professional (annual, custom quote); docs gate Prospector Pro, Quick Search, Industries and Lists to 'Professional, Elite, and Enterprise' (Elite/Enterprise no longer on the pricing page). Docs also offer a 'free API key' Google form.
Auth header is the raw key: 'Authorization: <key>', no 'Bearer'.
Credits are only charged on contacts whose email_status is Valid or Accept All; Accept All (catch-all) still costs a credit.
Company name to domain matches exact name and returns the most-trafficked company; generic names can resolve to the wrong site.
Logo API is free only with a visible link back to uplead.com.

Before you build

Four things to settle first, each read off UpLead's own pages.

Confirm the API is on your planAPI access starts on the Professional plan. Free tier: Free Trial: $0 for 7 days, 5 credits, 1 user (no API listed).
Keep the key out of your codeAPI key. It is sent as: header Authorization: <api_key> (no Bearer prefix).
Design around the rate limit500 requests per minute.
Know the catch before you scalePlan gating conflict: pricing page shows Enrichment API, Prospector Pro API and Full API Access only on Professional (annual, custom quote); docs gate Prospector Pro, Quick Search, Industries and Lists to 'Professional, Elite, and Enterprise' (Elite/Enterprise no longer on the pricing page).
