API Reference

The OutPulse REST API lets you verify emails, find contacts, manage leads and sequences, and check deliverability from your own applications. All endpoints return JSON.

Authentication

Authenticate by passing your API key in the Authorization header. Generate keys in Settings → API Access.

curl -X POST https://outpulse.io/api/verify/single \
  -H "Authorization: Bearer op_your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{"email":"john@acme.com"}'

Errors

Errors return a JSON body with an error string. Standard HTTP status codes are used.

Rate Limits

API calls are metered against your plan's credit balance. Each single verification or finder lookup costs 1 credit. Bulk jobs cost 1 credit per email processed. Hitting your credit limit returns 402. Rate-limited requests (too many per minute) return 429.

Email Verification

Verify individual email addresses or submit bulk jobs.

{"email":"john@acme.com"}

{"emails":["a@acme.com","b@acme.com"]}

Email Finder

Find email addresses by name + domain or by company domain.

{"firstName":"John","lastName":"Doe","domain":"acme.com"}

Leads

Create, list, and manage leads.

{"email":"jane@acme.com","firstName":"Jane","lastName":"Doe"}

Deliverability

Check SPF, DKIM, and DMARC configuration for a sender domain.
