print(profile["full_name"], "->", profile["headline"])

Key Engineering Takeaways (TL;DR)

✓B2BProfile API exposes `/api/v2/linkedin` as a native alias for `/v1/profile` so existing `?url=https://www.linkedin.com/in/...` requests work immediately.
✓Both `x-api-key: b2b_live_...` and `Authorization: Bearer b2b_live_...` headers are accepted out of the box.
✓Every profile response includes chronological `experiences`, `educations`, `skills`, `languages`, and current employer fields.

1. Endpoint & Parameter Mapping Table

You can either use our canonical /v1/* routes or keep your existing Proxycurl path strings during migration.

Proxycurl to B2BProfile API Route & Cost Mapping
Use Case	Legacy Proxycurl Route	B2BProfile API Canonical / Alias	B2BProfile API Cost
Person Profile Lookup	GET / proxycurl/api/v2/linkedin?url=...	GET /v1/profile or GET /api/v2/linkedin	10 Credits ($0.0004–$0.001)
Company Lookup	GET / proxycurl/api/linkedin/company?url=...	GET /v1/company or GET /api/linkedin/company	10 Credits ($0.0004–$0.001)
Employee Listing	GET / proxycurl/api/linkedin/company/employees	GET /v1/people/search or GET /v1/company/employees	2 Credits / person returned
Job Search	GET / proxycurl/api/v2/linkedin/company/job	GET /v1/jobs/search or GET /v1/company/jobs	2 Credits / job returned

2. Side-by-Side Code Migration

Swap the base URL and API key environment variable—your Bearer token header continues to work unchanged.

Drop-In `/api/v2/linkedin` Compatibility Call

Call `/api/v2/linkedin` or `/v1/profile` with a full profile URL or username:

curl "https://api.b2bprofileapi.com/api/v2/linkedin?url=https://www.linkedin.com/in/satyanadella" \
  -H "Authorization: Bearer b2b_live_your_api_key"
